[0047] Detailed description

[0048] The following is a more detailed description of various concepts and embodiments related to methods and apparatus for providing an aftertreatment component cartridge for an aftertreatment system. The various concepts introduced above and discussed in greater detail below can be implemented in any of a variety of ways, as the concepts described are not limited to any particular embodiment. Examples of specific embodiments and applications are provided primarily for illustrative purposes.

[0049] I. Overview

[0050] In order to reduce emissions, it may be desirable to use an aftertreatment system component to treat the exhaust. After the aftertreatment system component has treated a certain amount of exhaust, the aftertreatment system component may need to be repaired or replaced. In addition, it may sometimes be necessary to remove the aftertreatment component cartridge and replace it with a different aftertreatment system component, thereby reusing the aftertreatment system from one application to another. In many aftertreatment systems, removing, repairing, and replacing aftertreatment system components may be difficult or impossible because the aftertreatment system components are non-removable and / or not easily accessible to the user. One way to repair and replace aftertreatment system components is to secure the aftertreatment system components to the aftertreatment system with multiple clamps. However, the use of multiple clamps increases the overall cost and space of the aftertreatment system, limiting the space available for other systems. The use of multiple clamps also reduces the area available for insulation on the outside of the aftertreatment system. In addition, the use of multiple clamps increases the number of connections and openings through which exhaust gas can escape, which may increase the temperature of the outside of the aftertreatment system and surrounding components.

[0051] Aftertreatment systems are subject to space requirements, which are the amount of physical space consumed by the aftertreatment system when installed (e.g., on a vehicle, etc.) and the location of the physical space consumed by the aftertreatment system when installed (e.g., coordinates relative to the vehicle's coordinate system, etc.). In some applications, the physical space available for the aftertreatment system is limited due to the location of surrounding components, wiring or piping requirements, or other similar constraints. Consequently, it is often difficult to modify the aftertreatment system because such modifications typically increase the space requirements of the aftertreatment system. Such modifications may be required to utilize various components in the aftertreatment system, such as different types of filters or catalysts.

[0052] Embodiments described herein relate to an aftertreatment system comprising an inlet duct assembly, an outlet duct assembly, and at least one aftertreatment component cartridge containing aftertreatment system components. The inlet duct assembly includes an inlet coupling flange portion, and the outlet duct assembly includes an outlet coupling flange portion. The aftertreatment component cartridge includes an adapter that cooperates with the inlet and outlet coupling flanges and facilitates suspension of the aftertreatment system components within a housing by securing the aftertreatment component cartridge to the inlet and outlet bodies using fasteners (e.g., clamps, bolted connections, V-belt body connections, etc.). As such, internal combustion engines utilizing the aftertreatment system described herein are more desirable than other aftertreatment systems that require multiple clamps and cannot be quickly installed, repaired, replaced, and reused (e.g., by changing the type of one or more aftertreatment components). Furthermore, by configuring the inlet and outlet coupling flanges and the adapter in this arrangement to be retained by fasteners, the space requirements of the aftertreatment system described herein can be significantly less than those of other systems that do not utilize such an arrangement. Furthermore, by using fasteners in such an arrangement, the area on the exterior of the aftertreatment system for insulation is increased, and the number of connections and openings through which exhaust gas may escape is reduced.

[0053] II. Overview of Example Post-Processing Systems

[0054] Figures 1 to 14 An aftertreatment system 100 (e.g., a treatment system, etc.) is depicted for treating exhaust gas generated by an internal combustion engine (e.g., a diesel internal combustion engine, a gasoline internal combustion engine, a hybrid internal combustion engine, a propane internal combustion engine, a dual-fuel internal combustion engine, etc.) As explained in greater detail herein, the aftertreatment system 100 facilitates simpler and faster servicing (e.g., by changing the type of one or more aftertreatment components, etc.) than other systems, thereby making the aftertreatment system 100 more desirable than other systems.

[0055] Aftertreatment system 100 includes an inlet duct assembly 102 (e.g., a piping system, a ducting system, etc.). Inlet duct assembly 102 includes an inlet exhaust conduit 104 (e.g., a ducting system, etc.), which receives exhaust gas from an upstream component (e.g., a header on an internal combustion engine, an exhaust manifold on an internal combustion engine, an internal combustion engine, etc.). In some embodiments, inlet exhaust conduit 104 is coupled (e.g., attached, fixed, welded, fastened, riveted, adhesively attached, bonded, pinned, etc.) to the upstream component. In other embodiments, inlet exhaust conduit 104 is integrally formed with the upstream component.

[0056] The inlet duct assembly 102 also includes an inlet body 106 (e.g., a body, a panel, etc.). The inlet duct assembly 102 also includes an inlet housing 108 (e.g., a housing, a body, etc.). The inlet housing 108 surrounds the inlet body 106 to contain the inlet body 106. The inlet housing 108 includes a first inlet housing flange 110 (e.g., an annular protrusion, a circular ridge, an annular rib, etc.) to couple the inlet housing 108 to the inlet body 106. The inlet housing 108 also includes a second inlet housing flange 112 (e.g., an annular protrusion, a circular ridge, an annular rib, etc.) to couple the inlet housing 108 to the inlet body 106. The inlet body 106 includes an inlet body wall portion 114 (e.g., a body, a panel, etc.). The inlet body wall portion 114 receives the exhaust flow from the inlet exhaust duct 104.

[0057] In some embodiments, the inlet exhaust duct 104 includes an inlet exhaust duct flange 116 (e.g., an annular protrusion, a circular ridge, an annular rib, etc.) disposed between and coupled to the inlet body wall portion 114 and the first inlet housing flange 110. The inlet exhaust duct flange 116 may facilitate coupling of the inlet exhaust duct 104 to the inlet duct assembly 102.

[0058] In some embodiments, the inlet duct assembly 102 further includes an inlet insulator 118 (e.g., insulation, mat, etc.). The inlet insulator 118 is disposed between the inlet body wall portion 114 and the inlet housing 108. When the exhaust gas enters the inlet duct assembly 102, the inlet insulator 118 is used to reduce the increase in the temperature of the inlet housing 108. The inlet insulator 118 can be, for example, an insulation mat, a ceramic fiber mat, or other similar components.

[0059] The inlet body 106 also includes an inlet coupling flange portion 120 (e.g., an annular protrusion, a circular ridge, an annular rib, etc.). The inlet coupling flange portion 120 is downstream of the inlet body wall portion 114 and flares outward (e.g., radially outward and axially outward, etc.) from the inlet body wall portion 114. More specifically, the inlet coupling flange portion 120 extends from the inlet body wall portion 114 along an inclined surface. The inclined surface is angled relative to a reference plane that bisects the inlet body 106.

[0060] In some embodiments, the inlet body 106 further includes an inlet curved portion 122, such as Figure 3-Figure 5As shown. The inlet bend portion 122 is adjacent to the inlet body wall portion 114 and the inlet coupling flange portion 120. Similar to the inlet coupling flange portion 120, the inlet bend portion 122 is flared outward. More specifically, the inlet bend portion 122 extends from the inlet body wall portion 114 along an inclined surface, and the inlet coupling flange portion 120 extends from the inlet bend portion 122 along an inclined surface. Thus, the inlet bend portion 122 creates a gap inside the aftertreatment system 100 to accommodate additional components, as described in more detail herein. The inclined surface is angled with respect to a reference plane that bisects the inlet body 106. The angle of the inclined surface of the inlet coupling flange portion 120 is greater than the angle of the inclined surface of the inlet bend portion 122 (for example, where Figure 4 ( , the angles are measured counterclockwise, etc.). For example, the angular difference may be between approximately 10 and 30 degrees. This angular difference provides the inlet body 106 with a shape that facilitates coupling to other components of the aftertreatment system 100, as described in greater detail herein.

[0061] Return Reference Figures 1 to 14 As explained in more detail below, the aftertreatment system 100 also includes an outlet conduit assembly 124 (e.g., a piping system, a ducting system, etc.). As explained in more detail herein, the outlet conduit assembly 124 is configured to provide exhaust gas from the aftertreatment system 100 (e.g., to downstream components, to the atmosphere, etc.).

[0062] The outlet duct assembly 124 includes an outlet exhaust conduit 126 (e.g., a piping system, a ducting system, etc.). The outlet exhaust conduit 126 provides exhaust gas from the aftertreatment system 100. The outlet duct assembly 124 also includes an outlet body 128 (e.g., a body, a panel, etc.). The outlet duct assembly 124 also includes an outlet housing 130 (e.g., a housing, a body, etc.). The outlet housing 130 surrounds the outlet body 128 to contain the outlet body 128. The outlet body 128 includes an outlet body wall portion 132 (e.g., a body, a panel, etc.).

[0063] In some embodiments, the outlet duct assembly 124 further includes an outlet insulator 134 (e.g., insulation, mat, etc.). The outlet insulator 134 is disposed between the outlet body wall portion 132 and the outlet housing 130. The outlet insulator 134 is used to mitigate the increase in temperature of the outlet housing 130. The inlet insulator 118 may be, for example, an insulation mat, a ceramic fiber mat, or other similar component.

[0064] The outlet body 128 also includes an outlet coupling flange portion 136 (e.g., an annular protrusion, a circular ridge, an annular rib, etc.). The outlet coupling flange portion 136 is located upstream of the outlet body wall portion 132 and flares outward from the outlet body wall portion 132. More specifically, the outlet coupling flange portion 136 extends from the outlet body wall portion 132 along an inclined surface. The outlet coupling flange portion 136 extends from the outlet body wall portion 132 along the inclined surface in a first direction, and the inlet coupling flange portion 120 extends from the inlet body wall portion 114 along the inclined surface in a second direction opposite to the first direction. The outlet coupling flange portion 136 extends from the outlet body wall portion 132 along the inclined surface in the first direction, and the inlet coupling flange portion 120 extends from the inlet body wall portion 114 along the inclined surface in the first direction.

[0065] In some embodiments, the outlet body 128 further includes an outlet bend 138, such as Figures 3 to 5 As shown. The outlet bend 138 abuts the outlet body wall portion 132 and the outlet coupling flange portion 136. Similar to the outlet coupling flange portion 136, the outlet bend 138 flares outward. More specifically, the outlet bend 138 extends from the outlet body wall portion 132 along an inclined surface, and the outlet coupling flange portion 136 extends from the outlet bend 138 along an inclined surface. The outlet bend 138 extends from the outlet body wall portion 132 along the inclined surface in a first direction, and the inlet coupling flange portion 120 extends from the inlet body wall portion 114 along the inclined surface in a second direction opposite the first direction. The outlet bend 138 extends from the outlet body wall portion 132 along the inclined surface in the first direction, and the inlet coupling flange portion 120 extends from the inlet body wall portion 114 along the inclined surface in the first direction. Thus, the outlet bend 138 creates a gap within the interior of the aftertreatment system 100 that can accommodate additional components, as described in more detail herein. The inclined surface is angled relative to a reference plane that bisects the outlet body 128. The angle of the inclined surface of the outlet curved portion 138 is greater than the angle of the inclined surface of the outlet coupling flange portion 136 (for example, Figure 4 , the angles are measured counterclockwise, etc.). For example, the angular difference may be between approximately 10 and 30 degrees. This angular difference provides the outlet body 128 with a shape that facilitates coupling with other components of the aftertreatment system 100, as described in greater detail herein.

[0066] exist Figures 2 to 4 , aftertreatment system 100 includes an aftertreatment component cartridge 140 (e.g., cartridge, insert, etc.). As explained in greater detail herein, inlet coupling flange portion 120 and outlet coupling flange portion 136 cooperate to facilitate suspension of aftertreatment component cartridge 140 within inlet body 106 and outlet body 128.

[0067] like Figure 4 As shown, aftertreatment component cartridge 140 includes an aftertreatment component housing 142 (eg, a filter housing, etc.) Aftertreatment component housing 142 facilitates the flow of exhaust gas from inlet duct assembly 102 into aftertreatment component cartridge 140 .

[0068] Aftertreatment component housing 142 includes an inlet portion 144. Inlet portion 144 is inserted into inlet duct assembly 102. Inlet portion 144 receives exhaust gas from inlet duct assembly 102 and provides the exhaust gas to aftertreatment component canister 140. Aftertreatment component housing 142 also includes an outlet portion 146. Outlet portion 146 is inserted into outlet duct assembly 124. Outlet portion 146 receives exhaust gas from aftertreatment component canister 140 and provides the exhaust gas from aftertreatment component canister 140.

[0069] like Figures 2 to 4 As shown, the aftertreatment component cartridge 140 includes an aftertreatment system component 148. The aftertreatment system component 148 is positioned within the aftertreatment component housing 142. The aftertreatment system component 148 treats exhaust gas generated by the internal combustion engine. In some embodiments, the aftertreatment system component 148 reduces unwanted components (e.g., nitrogen oxides (NO x ) etc. In some embodiments, aftertreatment system component 148 facilitates the removal of particulates (e.g., soot, particulate matter, etc.) from the exhaust gas via a filtering member (e.g., a diesel particulate filter (DPF) etc.). In other embodiments, aftertreatment system component 148 is a conversion catalyst member (e.g., a selective catalytic reduction (SCR) conversion catalyst member, a catalyst metal, etc.) that facilitates the conversion of various oxidized components of the exhaust gas (e.g., carbon monoxide (CO), hydrocarbons, etc.) into other components (e.g., carbon dioxide (CO2), water vapor, etc.).

[0070] like Figure 5 、 Figure 7 、 Figure 10 and Figure 13 As shown, the aftertreatment component cartridge 140 is not limited to housing a single aftertreatment system component 148. Rather, the aftertreatment component cartridge 140 may include more than one aftertreatment system component 148, each of which may be any embodiment described herein. In some embodiments, the two aftertreatment system components 148 are identical. For example, both aftertreatment system components 148 may be conversion catalyst components. In another example, both aftertreatment system components 148 may be filter components. In other embodiments, the aftertreatment system components 148 are different from one another. For example, the upstream aftertreatment system component 148 may be a filter component, while the downstream aftertreatment system component 148 may be a conversion catalyst component.

[0071] In some embodiments, aftertreatment component cartridge 140 further includes a mounting pad 150 (e.g., a compressible pad, etc.) disposed between aftertreatment system component 148 and aftertreatment component housing 142. Mounting pad 150 may facilitate coupling of aftertreatment system component 148 to aftertreatment component housing 142.

[0072] Return Reference Figure 4 , the after-treatment component cartridge 140 includes an adapter 152 (e.g., a protrusion, a ridge, a rib, etc.). The adapter 152 is coupled to the after-treatment component housing 142. The adapter 152 cooperates with the after-treatment component housing 142, the inlet coupling flange portion 120, and the outlet coupling flange portion 136 to facilitate suspension of the after-treatment component cartridge 140 within the inlet body 106 and the outlet body 128 when a compressive force is applied to the adapter 152. Different embodiments of the adapter 152 can use different fasteners (e.g., clamps, compression connections, V-belt body connections, etc.) to compress the adapter 152 and suspend the after-treatment component cartridge 140 within the inlet body 106 and the outlet body 128, as described in more detail herein.

[0073] In some embodiments, adapter 152 includes a first flange portion 154 (e.g., a ring, etc.) coupled to inlet portion 144 and a second flange portion 156 (e.g., a ring, etc.) coupled to outlet portion 146. By coupling first flange portion 154 to inlet portion 144 and second flange portion 156 to outlet portion 146, first flange portion 154 and second flange portion 156 facilitate suspension of aftertreatment component cartridge 140 within inlet body 106 and outlet body 128 when a compressive force is applied to adapter 152. When first flange portion 154 is coupled to inlet portion 144, first flange portion 154 is disposed between inlet body wall portion 114 and inlet portion 144. Similarly, when second flange portion 156 is coupled to outlet portion 146, second flange portion 156 is disposed between outlet body wall portion 132 and outlet portion 146. In some embodiments, a user may receive aftertreatment component cartridge 140 with first flange portion 154 already coupled to inlet portion 144 and second flange portion 156 already coupled to outlet portion 146 .

[0074] In other embodiments, the first flange portion 154 and the second flange portion 156 are initially separate from the inlet portion 144 and the outlet portion 146, respectively. In these embodiments, a user can couple the first flange portion 154 to the inlet portion 144 and the second flange portion 156 to the outlet portion 146 during an installation process (e.g., method, etc.) to install the aftertreatment component cartridge 140 of the aftertreatment system 100. Figure 15 Various examples of such installation procedures are described.

[0075] In some embodiments, the adapter 152 includes a first connecting wall portion 157. The first connecting wall portion 157 is adjacent to the first flange portion 154. A portion of the first connecting wall portion 157 extends from the first flange portion 154 along the inclined surface. Figure 3 As shown, the first connecting wall portion 157 includes a first flat portion 158. The first flat portion 158 is adjacent to the first connecting wall portion 157. The first flat portion 158 is parallel to the central axis λ.

[0076] Similarly, in some embodiments, the adapter 152 includes a second connecting wall portion 159. The second connecting wall portion 159 is adjacent to the second flange portion 156. A portion of the second connecting wall portion 159 extends from the second flange portion 156 along the inclined surface. Figure 3 As shown, the second connecting wall portion 159 includes a second flat portion 160. The second flat portion 160 is adjacent to the second connecting wall portion 159. The second flat portion 160 is parallel to the central axis λ.

[0077] Additionally, the adapter 152 includes a coupler portion 161 (eg, an annular protrusion, a circular ridge, an annular rib, etc.), such as Figure 4 As shown, coupling portion 161 is disposed between and connects first flange portion 154 and second flange portion 156. Thus, when a compressive force is applied to adapter 152, coupling portion 161 enables first flange portion 154 to suspend inlet portion 144 while also enabling second flange portion 156 to suspend outlet portion 146. Furthermore, coupling portion 161 extends between inlet coupling flange portion 120 of inlet body 106 and outlet coupling flange portion 136 of outlet body 128.

[0078] In some embodiments, coupling portion 161 includes a first coupling wall portion 162 (e.g., a plate, a body, etc.). First coupling wall portion 162 cooperates with inlet coupling flange portion 120 to suspend after-treatment component cartridge 140. Similarly, coupling portion 161 includes a second coupling wall portion 163 (e.g., a plate, a body, etc.). Second coupling wall portion 163 cooperates with outlet coupling flange portion 136 to suspend after-treatment component cartridge 140.

[0079] The first coupling wall portion 162 is located downstream of the first flange portion 154 and is adjacent to the first flange portion 154. The first coupling wall portion 162 extends from the first flange portion 154 along an inclined surface such that the first coupling wall portion 162 is parallel to the inlet coupling flange portion 120, resulting in the inlet coupling flange portion 120 and the first coupling wall portion 162 being in a facing relationship. The inclined surface is angled with respect to a reference plane that bisects the adapter 152. The angle of the inclined surface of the first coupling wall portion 162 is greater than the angle of the inclined surface of the first connecting wall portion 157 (e.g., wherein Figure 4 ( , angles are measured counterclockwise, etc.). For example, the angular difference can be between approximately 20 and 80 degrees. This angular difference allows adapter 152 to have a shape that facilitates coupling to other components of aftertreatment system 100, as described in greater detail herein. In some embodiments, first coupling wall portion 162 abuts first connecting wall portion 157, and a portion of first coupling wall portion 162 extends from first connecting wall portion 157 along an inclined surface.

[0080] The second coupling wall portion 163 is located upstream of the second flange portion 156 and is adjacent to the second flange portion 156. The second coupling wall portion 163 extends from the second flange portion 156 along an inclined surface so that the second coupling wall portion 163 is parallel to the outlet coupling flange portion 136, resulting in the outlet coupling flange portion 136 and the second coupling wall portion 163 being in a facing relationship. The inclined surface is angled with respect to the reference plane that bisects the adapter 152. The angle of the inclined surface of the second connecting wall portion 159 is greater than the angle of the inclined surface of the second coupling wall portion 163 (for example, where Figure 4 ( , angles are measured counterclockwise, etc.). For example, the angular difference can be between approximately 20 and 80 degrees. This angular difference allows adapter 152 to have a shape that facilitates coupling to other components of aftertreatment system 100, as described in greater detail herein. In some embodiments, second coupling wall portion 163 abuts second connecting wall portion 159, and a portion of second coupling wall portion 163 extends from second connecting wall portion 159 along an inclined surface.

[0081] Thus, when compressive forces are applied to inlet coupling flange portion 120 and outlet coupling flange portion 136 , compressive forces are also applied to first coupling wall portion 162 and second coupling wall portion 163 , enabling adapter 152 to suspend aftertreatment system component 148 within inlet body 106 and outlet body 128 .

[0082] The adapter 152 also includes a radial wall portion 164 (e.g., a plate, a body, etc.) that extends between the first coupling wall portion 162 and the second coupling wall portion 163. The radial wall portion 164 is adjacent to the first coupling wall portion 162 and the second coupling wall portion 163 and is radially spaced apart from the aftertreatment component housing 142.

[0083] refer to Figures 2 to 4 In some embodiments, the aftertreatment system 100 includes a first gasket 166 (e.g., a gasket, seal, plug, etc.). The first gasket 166 can be made of a compressible material (e.g., rubber, elastomer, etc.). The first gasket 166 is disposed between the inlet coupling flange portion 120 and the first coupling wall portion 162 such that the first gasket 166 is spaced apart from the aftertreatment component housing 142 via the adapter 152. The first gasket 166 establishes a seal between the inlet coupling flange portion 120 and the first coupling wall portion 162. Thus, when a compressive force is applied to the inlet coupling flange portion 120, the first gasket 166 is compressed between the inlet coupling flange portion 120 and the first coupling wall portion 162.

[0084] Similarly, aftertreatment system 100 can include a second gasket 168 (e.g., a gasket, seal, plug, etc.). Second gasket 168 can be made of a compressible material (e.g., rubber, elastomer, etc.). Second gasket 168 is disposed between outlet coupling flange portion 136 and second coupling wall portion 163 such that second gasket 168 is spaced apart from aftertreatment component housing 142 via adapter 152. Second gasket 168 establishes a seal between outlet coupling flange portion 136 and second coupling wall portion 163. Thus, when a compressive force is applied to outlet coupling flange portion 136, second gasket 168 is compressed between outlet coupling flange portion 136 and second coupling wall portion 163. Both first gasket 166 and second gasket 168 are creep-resistant, such that the connection preload is not significantly reduced during prolonged compression of inlet coupling flange portion 120 and outlet coupling flange portion 136 with first coupling wall portion 162 and second coupling wall portion 163.

[0085] In another embodiment, only the first gasket 166 is used. When only the first gasket 166 is used, the first gasket 166 is disposed between the first coupling wall portion 162, the inlet coupling flange portion 120, the second coupling wall portion 163, and the outlet coupling flange portion 136, such that the first gasket 166 is spaced apart from the aftertreatment component housing 142 via the adapter 152. The first gasket 166 establishes a seal between the first coupling wall portion 162, the inlet coupling flange portion 120, the second coupling wall portion 163, and the outlet coupling flange portion 136. Thus, when a compressive force is applied to the inlet coupling flange portion 120, the first gasket 166 is compressed between the inlet coupling flange portion 120 and the first coupling wall portion 162. When a compressive force is applied to the outlet coupling flange portion 136, the first gasket 166 is compressed between the outlet coupling flange portion 136 and the second coupling wall portion 163. The first gasket 166 may be creep resistant such that the connection preload is not significantly reduced during prolonged compression of the inlet and outlet coupling flange portions 120 and 136 with the first and second coupling wall portions 162 and 163 .

[0086] Return Reference Figure 3 In some embodiments, the aftertreatment system 100 is centered about a central axis λ. The aftertreatment component barrel 140 is bisected by a radial plane BB that intersects and is orthogonal to the central axis λ. Furthermore, at least a portion of the inlet coupling flange portion 120 is disposed along an inlet coupling flange plane CC. The angle between the inlet coupling flange plane CC and the radial plane BB is approximately between 10 and 30 degrees (e.g., 5, 10, 15, 25, 30, 35, etc.). Similarly, at least a portion of the first coupling wall portion 162 is disposed along a first coupling wall plane DD. The first coupling wall plane DD is spaced from the radial plane BB by an angle approximately between 10 and 30 degrees (e.g., 5, 10, 15, 25, 30, 35, etc.).

[0087] In some of these embodiments, the angles between the inlet coupling flange plane CC and the first coupling wall plane DD and the radial plane BB are equal. Therefore, the first coupling wall portion 162 is parallel to the inlet coupling flange portion 120 .

[0088] In some embodiments, at least a portion of the outlet coupling flange portion 136 is disposed along an outlet coupling flange plane EE. The angle between the outlet coupling flange plane EE and the radial plane BB is approximately between 280 and 300 degrees (e.g., 275, 280, 285, 295, 300, 305, etc.). Similarly, at least a portion of the second coupling wall portion 163 is disposed along a second coupling wall plane FF. The angle between the second coupling wall plane FF and the radial plane BB is approximately between 280 and 300 degrees (e.g., 275, 280, 285, 295, 300, etc.).

[0089] In some of these embodiments, the outlet coupling flange plane EE and the second coupling wall plane FF have equal angles with the radial plane BB.

[0090] As previously described, different embodiments of the adapter 152 can utilize different fasteners to compress the adapter 152 and facilitate suspension of the aftertreatment component cartridge 140 within the inlet body 106 and the outlet body 128 . Figures 6 to 11 is a cross-sectional view of the aftertreatment system 100, depicting embodiments with different adapters 152. For example, in Figures 6 to 8 In the embodiment of the present invention, a coupling portion 161 of the adapter 152 is coupled to the first flange portion 154 and the second flange portion 156. The coupling portion 161 is positioned radially outward from the aftertreatment component housing 142 such that the coupling portion 161 is orthogonal to the aftertreatment component housing 142. When a compressive force is applied to the inlet coupling flange portion 120 and the outlet coupling flange portion 136, the coupling portion 161 is compressed between the inlet coupling flange portion 120 and the outlet coupling flange portion 136. By compressing the coupling portion 161, the adapter 152 is able to suspend the aftertreatment system component 148 within the aftertreatment system 100 by securing the aftertreatment component cartridge 140 to the inlet body 106 and the outlet body 128.

[0091] For example, Figure 8 and Figure 11 As shown, in some embodiments, aftertreatment system 100 includes a first gasket 166. First gasket 166 is disposed between inlet coupling flange portion 120 and coupler portion 161 such that first gasket 166 is spaced apart from aftertreatment component housing 142 via adapter 152. First gasket 166 establishes a seal between inlet coupling flange portion 120 and coupler portion 161. Thus, when a compressive force is applied to inlet coupling flange portion 120, first gasket 166 is compressed between inlet coupling flange portion 120 and coupler portion 161.

[0092] A second gasket 168 is disposed between the outlet coupling flange portion 136 and the coupler portion 161 such that the second gasket 168 is spaced apart from the aftertreatment component housing 142 via the adapter 152. The second gasket 168 establishes a seal between the outlet coupling flange portion 136 and the coupler portion 161. Thus, when a compressive force is applied to the outlet coupling flange portion 136, the second gasket 168 is compressed between the outlet coupling flange portion 136 and the coupler portion 161. Both the first gasket 166 and the second gasket 168 can be creep-resistant such that the connection preload is not significantly reduced during prolonged compression of the inlet coupling flange portion 120 and the outlet coupling flange portion 136 with the coupler portion 161.

[0093] refer to Figure 11 Aftertreatment component barrel 140 is bisected by radial plane BB, which intersects and is orthogonal to central axis λ. Furthermore, at least a portion of inlet coupling flange portion 120 is disposed along inlet coupling flange plane CC, and at least a portion of outlet coupling flange portion 136 is disposed along outlet coupling flange plane EE. Inlet coupling flange plane CC and outlet coupling flange plane EE are orthogonal to central axis λ. Therefore, inlet coupling flange portion 120 and outlet coupling flange portion 136 are parallel.

[0094] refer to Figures 12 to 14 In other embodiments, the adapter 152 includes a first coupling wall portion 162 coupled to the inlet portion 144 of the after-treatment component housing 142 and disposed between the inlet coupling flange portion 120 and the after-treatment component housing 142. The adapter 152 also includes a second coupling wall portion 163 coupled to the outlet portion 146 of the after-treatment component housing 142 and disposed between the outlet coupling flange portion 136 and the after-treatment component housing 142. The coupling portion 161 is adjacent to the first coupling wall portion 162 and the second coupling wall portion 163 and extends between the inlet coupling flange portion 120 and the outlet coupling flange portion 136. The coupling portion 161 includes a radial wall portion 164 adjacent to the first coupling wall portion 162 and the second coupling wall portion 163 and spaced apart from the after-treatment component housing 142.

[0095] refer to Figure 14In some embodiments, at least a portion of the inlet coupling flange portion 120 is disposed along an inlet coupling flange plane CC, with the angle between the inlet coupling flange plane CC and the radial plane BB being approximately between 30 and 60 degrees (e.g., 25, 30, 40, 50, 60, 35, etc.). Similarly, at least a portion of the first coupling wall portion 162 is disposed along a first coupling wall plane DD, with the angle between the first coupling wall plane DD and the radial plane BB being approximately between 30 and 60 degrees (e.g., 25, 30, 40, 50, 60, 35, etc.). In some of these embodiments, the angles between the inlet coupling flange plane CC and the first coupling wall plane DD and the radial plane BB are equal. Thus, the first coupling wall portion 162 is parallel to the inlet coupling flange portion 120.

[0096] refer to Figure 14 In some embodiments, at least a portion of the outlet coupling flange portion 136 is disposed along an outlet coupling flange plane EE, which is positioned at an angle between approximately 300 degrees and 330 degrees (e.g., 295 degrees, 300 degrees, 315 degrees, 325 degrees, 330 degrees, 335 degrees, etc.) to the radial plane BB. Similarly, at least a portion of the second coupling wall portion 163 is disposed along a second coupling wall plane FF, which is positioned at an angle between approximately 300 degrees and 330 degrees (e.g., 295 degrees, 300 degrees, 315 degrees, 325 degrees, 330 degrees, 335 degrees, etc.) to the radial plane BB. In these embodiments, the angles between the outlet coupling flange plane EE and the second coupling wall plane FF and the radial plane BB are equal. Thus, the second coupling wall portion 163 is parallel to the outlet coupling flange portion 136.

[0097] The adapter 152 is configured to couple to the aftertreatment component housing 142 at various locations. For example, in some embodiments, the aftertreatment component cartridge 140 is centered about the central axis λ, as shown in FIG. Figure 3As shown, adapter 152 is centered on radial plane BB, which is orthogonal to central axis λ, intersects central axis λ, and bisects aftertreatment component cartridge 140. Furthermore, aftertreatment component cartridge 140 includes an inlet plane GG parallel to radial plane BB. Similarly, aftertreatment component cartridge 140 includes an outlet plane HH parallel to radial plane BB. Both inlet plane GG and outlet plane HH extend along a portion of aftertreatment component cartridge 140, such that aftertreatment component cartridge 140 is disposed between inlet plane GG and outlet plane HH. Inlet plane GG and outlet plane HH are separated by a first distance L1 along central axis λ. Radial plane BB is separated from inlet plane GG by a second distance L2 along central axis λ. In various embodiments, second distance L2 is approximately between 40% and 60% of first distance L1 (e.g., 35%, 40%, 45%, 55%, 60%, 65%, etc.). In other embodiments, the second distance L2 may be approximately between 60% and 80% of the first distance L1 (eg, 55%, 60%, 65%, 75%, 80%, 85%, etc.).

[0098] In various embodiments, the adapter 152 can be configured in other ways than described above. For example, the adapter 152 can be coupled to the aftertreatment component housing 142 at the center of mass of the aftertreatment component cartridge 140. In another example having more than one aftertreatment system component 148, the adapter 152 can be coupled to the aftertreatment component housing 142 at a midpoint between the outlet of one aftertreatment system component 148 and the inlet of another aftertreatment system component 148.

[0099] In some embodiments, the fastener is a clamp 170 (e.g., a hoop, a band clamp, etc.) that applies a compressive force to secure the aftertreatment component cartridge 140 to the inlet body 106 and the outlet body 128 and suspend the aftertreatment component cartridge 140 in the aftertreatment system 100, as shown. Figure 3 、 Figure 8 and Figure 14 As shown, the clamp 170 includes a first clamp flange portion 172. The first clamp flange portion 172 compresses the inlet coupling flange portion 120 toward the first coupling wall portion 162. In this manner, the clamp 170 couples the aftertreatment component cartridge 140 to the inlet body 106. The clamp 170 may include a bolt and a nut that cooperate to tighten and loosen the clamp 170.

[0100] The clamp 170 also includes a second clamp flange portion 174. The second clamp flange portion 174 compresses the outlet coupling flange portion 136 toward the second coupling wall portion 163. In this manner, the clamp 170 also couples the aftertreatment component cartridge 140 to the outlet body 128.

[0101] In some embodiments, the clamp 170 includes a strap 176 (e.g., a ring, a strap, etc.). Figure 3 As shown, a strap 176 is disposed on an outer surface of the clamp 170. The clamp 170 also includes a winch 178 (e.g., an adjuster, etc.). The winch 178 is used to couple the strap 176 to the clamp 170. Thus, the clamp 170 facilitates the suspension of the aftertreatment component cartridge 140 within the inlet body 106 and the outlet body 128. By suspending the aftertreatment component cartridge 140 within the inlet body 106 and the outlet body 128 using the clamp 170, the aftertreatment system components 148 are more easily installed and removed (e.g., for replacement, maintenance, etc.), compared to aftertreatment systems that utilize multiple clamps, each of which must be removed to access the aftertreatment components. Unlike aftertreatment systems that utilize multiple clamps to suspend aftertreatment components, the use of the clamp 170 also provides additional mounting space on the exterior of the aftertreatment system 100, which provides greater overall insulation length and reduces the number of connections and openings through which exhaust gas may escape.

[0102] In other embodiments, the fastener is a compression connection 180 (e.g., a bolt connection, etc.). Figure 11 As shown, compression connection 180 applies a compressive force to secure aftertreatment component cartridge 140 to inlet body 106 and outlet body 128 and suspend aftertreatment component cartridge 140 within inlet body 106 and outlet body 128. Compression connection 180 also includes connection fasteners 182 (e.g., bolts, screws, threaded fasteners, etc.). Connection fasteners 182 facilitate attachment of compression connection 180 and compression of coupler portion 161 between inlet coupling flange portion 120 and outlet coupling flange portion 136. In some embodiments, inlet coupling flange portion 120, coupler portion 161, and outlet coupling flange portion 136 are threaded and threadedly engaged with compression connection 180.

[0103] III. Example Method of Installing an Aftertreatment Component Cartridge

[0104] Figure 15 An installation process 1500 (e.g., method, etc.) is shown for installing the aftertreatment component cartridge 140 of the aftertreatment system 100. The installation process 1500 may be performed by, including but not limited to, an original equipment manufacturer (i.e., when assembling the aftertreatment system 100, etc.) or a service technician (e.g., a mechanic, a production line worker, a robot, an automated machine, etc.).

[0105] In various embodiments, installation process 1500 begins at block 1502 with a service technician inserting first gasket 166 between first coupling wall portion 162 and inlet coupling flange portion 120. In various embodiments, installation process 1500 continues at block 1504 with a service technician inserting second gasket 168 between second coupling wall portion 163 and outlet coupling flange portion 136. In other embodiments, first gasket 166 and / or second gasket 168 are not included.

[0106] Installation process 1500 continues at block 1506 with a service technician inserting inlet portion 144 of aftertreatment component housing 142 into inlet body 106. Thus, first flange portion 154 is disposed between aftertreatment component housing 142 and inlet body wall portion 114.

[0107] Installation process 1500 continues at block 1508 with a service technician inserting outlet portion 146 of aftertreatment component housing 142 into outlet body 128. As a result, second flange portion 156 is disposed between aftertreatment component housing 142 and outlet body wall portion 132.

[0108] The installation process 1500 continues at block 1510 with a service technician placing the first coupling wall portion 162 in a facing relationship with the inlet coupling flange portion 120. The installation process 1500 continues at block 1512 with a service technician placing the second coupling wall portion 163 in a facing relationship with the outlet coupling flange portion 136.

[0109] The installation process 1500 continues at block 1514 with a service technician placing a clamp 170 (e.g., a hoop, a band clamp, etc.) over the inlet coupling flange portion 120 and the outlet coupling flange portion 136. As a result, the inlet coupling flange portion 120 and the first gasket 166 are disposed between the first clamp flange portion 172 and the first coupling wall portion 162. Additionally, the outlet coupling flange portion 136 and the second gasket 168 are disposed between the second clamp flange portion 174 and the second coupling wall portion 163.

[0110] The installation process 1500 continues at block 1516 with the service technician tightening the clamp 170 (e.g., by tightening a nut of the clamp 170, by tightening a bolt of the clamp 170, etc.). As a result, the first clamp flange portion 172 compresses the inlet coupling flange portion 120, such that the first gasket 166 is compressed between the first coupling wall portion 162 and the inlet coupling flange portion 120. Additionally, the second clamp flange portion 174 compresses the outlet coupling flange portion 136, such that the second gasket 168 is compressed between the second coupling wall portion 163 and the outlet coupling flange portion 136.

[0111] In some embodiments, the installation process 1500 can be performed without inserting the first gasket 166 and / or the second gasket 168 as described in blocks 1502 and 1504. In these embodiments, the installation process 1500 begins at block 1506 (e.g., skipping blocks 1502 and 1504).

[0112] IV. Example Method of Replacing an Aftertreatment Component Cartridge

[0113] Figure 16 A replacement process 1600 (eg, method, etc.) is shown for replacing an aftertreatment component cartridge 140 of an aftertreatment system 100 that has already been installed (eg, via installation process 1500, etc.). Replacement process 1600 may be performed by a service technician.

[0114] The replacement process 1600 begins at block 1602 with a service technician separating the clamp 170 from the inlet coupling flange portion 120 and the outlet coupling flange portion 136. Specifically, the first clamp flange portion 172 is separated from the inlet coupling flange portion 120, and the second clamp flange portion 174 is separated from the outlet coupling flange portion 136.

[0115] The replacement process 1600 continues at block 1604 with the service technician removing the inlet portion 144 from the inlet body 106. The replacement process 1600 continues at block 1606 with the service technician removing the outlet portion 146 from the outlet body 128.

[0116] In some embodiments, replacement process 1600 continues at block 1608 with a service technician separating first gasket 166 from first coupling wall portion 162. In such embodiments, first gasket 166 can be reused with a replacement post-treatment component cartridge 140. Similarly, in some embodiments, replacement process 1600 continues at block 1610 with a service technician separating second gasket 168 from second coupling wall portion 163. In such embodiments, second gasket 168 can be reused with a replacement post-treatment component cartridge 140.

[0117] The replacement process 1600 continues at block 1612 with the removal of the used aftertreatment component cartridge 140 by the service technician. The replacement process 1600 may be completed at block 1614 with the installation of a new aftertreatment component cartridge 140 by the service technician. The installation may be performed as described below. Figure 15 The installation process 1500 shown in FIG is completed.

[0118] In some embodiments, the replacement process 1600 may be performed without performing blocks 1608 and / or 1610 (e.g., when the aftertreatment component cartridge 140 is installed without the first gasket 166 and / or the second gasket 168). In such an application, after the inlet portion 144 is removed from the inlet body 106 at block 1604 and the outlet portion 146 is removed from the outlet body 128 at block 1606, the replacement process 1600 continues at block 1612 with the removal of the used aftertreatment component cartridge 140 by a service technician.

[0119] V. Overview of Additional Exemplary Aftertreatment Systems

[0120] Figures 17 to 34 An aftertreatment system 200 (e.g., a treatment system, etc.) is depicted for treating exhaust gas generated by an internal combustion engine (e.g., a diesel internal combustion engine, a gasoline internal combustion engine, a hybrid internal combustion engine, a propane internal combustion engine, a dual-fuel internal combustion engine, etc.) As explained in greater detail herein, aftertreatment system 200 facilitates simpler and faster assembly and / or repair (e.g., by changing the type of one or more aftertreatment components, etc.) than other systems, thereby making aftertreatment system 200 more desirable than other systems.

[0121] The aftertreatment system 200 is substantially similar to Figures 1-14 Aftertreatment system 100 is shown. For example, aftertreatment system 200 includes an inlet duct assembly 202 (e.g., a piping system, a ducting system, etc.) that is substantially similar to inlet duct assembly 102. Inlet duct assembly 202 includes an inlet exhaust duct 204 (e.g., a ducting system, etc.) that is substantially similar to inlet exhaust duct 104. For example, inlet exhaust duct 204 receives exhaust gas from an upstream component (e.g., a header on an internal combustion engine, an exhaust manifold on an internal combustion engine, an internal combustion engine, etc.). In some embodiments, inlet exhaust duct 204 is coupled (e.g., attached, fixed, welded, fastened, riveted, adhesively attached, bonded, pinned, etc.) to the upstream component. In other embodiments, inlet exhaust duct 204 is integrally formed with the upstream component.

[0122] The inlet duct assembly 202 also includes an inlet body 206 (e.g., a body, a panel, etc.). In some embodiments, the inlet duct assembly 202 also includes an inlet housing (not shown) that is substantially similar to the housing 108. The inlet body 206 includes an inlet body wall portion 214 (e.g., a body, a panel, etc.), also referred to herein as the "inlet body wall." The inlet body wall portion 214 receives the exhaust gas flow from the inlet exhaust duct 204.

[0123] In some embodiments, the inlet exhaust duct 204 includes an inlet exhaust duct flange (not shown) that is substantially similar to the inlet exhaust duct flange (116). For example, the inlet exhaust duct flange of the inlet exhaust duct 204 can be disposed between and coupled to the inlet body wall portions 214. The inlet exhaust duct flange can facilitate coupling of the inlet exhaust duct 204 to the inlet duct assembly 202.

[0124] In some embodiments, the inlet duct assembly 102 also includes an inlet insulator (not shown) that is substantially similar to the inlet insulator 118 .

[0125] The inlet body 206 also includes an inlet engagement member 220 (e.g., an annular protrusion, a circular ridge, an annular rib, etc.). The inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (e.g., radially outward and axially outward, etc.) from the inlet body wall portion 214. More specifically, the inlet engagement member 220 includes an inlet engagement member wall 222. At least a portion of the inlet engagement member 220 extends outward from the inlet body wall 214 and extends from the inlet body wall 214 along an inclined surface. The inclined surface is angled relative to the direction of extension of the inlet body 206. In some embodiments, the inclined surface is between 15° and 90° relative to the direction of extension of the inlet body 206.

[0126] The inlet coupling member 220 also includes an inlet coupling flange 223. In some embodiments, the inlet coupling flange 223 abuts the inlet coupling member wall 222 and extends outward (e.g., radially outward and axially outward, etc.) from the inlet coupling member wall 222 along an inclined surface and in a downstream direction. In other embodiments, a portion (e.g., a distal portion, a radially outward portion, etc.) of the inlet coupling member wall 222 defines the inlet coupling flange 223, such that the inlet coupling flange 223 is part of the inlet coupling member wall 222.

[0127] In some embodiments, the inlet engagement member 220 further includes an inlet curved portion 224, such as Figure 17-18 As shown, the inlet curved portion 224 is adjacent to the inlet body wall portion 214 and the inlet engaging member wall 222. The inlet curved portion 224 extends outward (e.g., radially outward and axially outward, etc.) from the inlet body wall portion 214. More specifically, the inlet curved portion 224 extends along a curved path between the inlet body wall 214 and the inlet engaging member wall 222.

[0128] In some embodiments, the inlet body 206 is configured to at least partially house a first catalyst assembly 226 (e.g., at least partially contain the first catalyst assembly 226 within the inlet body wall 214). The first catalyst assembly 226 includes a first catalyst housing 228 and a first catalyst member 230. The first catalyst housing 228 is coupled (e.g., fixed) to the inlet body wall 214. The first catalyst housing 228 is configured to house the first catalyst member 230. The first catalyst member 230 is a conversion catalyst member (e.g., a diesel oxidation catalyst (DOC) conversion catalyst member, a catalyst metal, etc.) that helps convert various components in the exhaust gas (e.g., carbon monoxide (CO), hydrocarbons, etc.) into other components (e.g., carbon dioxide (CO2), water vapor, etc.).

[0129] Aftertreatment system 200 also includes an outlet body 232 (eg, a system of lines, a system of ducts, etc.). Outlet body 232 is configured to provide exhaust gas from aftertreatment system 100 (eg, to downstream components, to the atmosphere, etc.).

[0130] The outlet body 232 includes an outlet exhaust conduit 234 (e.g., a piping system, a ducting system, etc.). The outlet exhaust conduit 234 provides exhaust gas from the aftertreatment system 200. The outlet body 232 also includes an outlet body wall portion 236 (e.g., a body, a panel, etc.), also referred to herein as the outlet body wall 236. In some embodiments, the outlet body 232 also includes an outlet housing substantially similar to the outlet housing 130. The outlet housing 130 surrounds the outlet body 128 to contain the outlet body 128. In some embodiments, the outlet body 232 also includes an outlet insulator (e.g., an insulator, a mat, etc.) substantially similar to the outlet insulator 134.

[0131] The outlet body 128 also includes an outlet engaging member 240 (e.g., an annular protrusion, a circular ridge, an annular rib, etc.). The outlet engaging member 240 is upstream of the outlet body wall portion 236 and flares or extends outward from the outlet body wall portion 236. More specifically, the outlet engaging member 240 includes an outlet engaging member wall 242. At least a portion of the outlet engaging member wall 242 extends outward from the outlet body wall 236 and extends from the outlet body wall 236 along an inclined surface. The inclined surface is angled relative to the direction of extension of the outlet body 232. The inclined surface is angled relative to the direction of extension of the outlet body 232. In some embodiments, the inclined surface is between 15° and 90° relative to the direction of extension of the outlet body 232.

[0132] Outlet coupling member 240 also includes an outlet coupling flange 243. In some embodiments, outlet coupling flange 243 abuts outlet coupling member wall 242 and extends outward (e.g., radially outward and axially outward, etc.) and in an upstream direction from outlet coupling member wall 242 along an inclined surface. In other embodiments, a portion (e.g., a distal portion, a radially outward portion, etc.) of outlet coupling member wall 242 defines outlet coupling flange 243, such that outlet coupling flange 243 is part of outlet coupling member wall 242.

[0133] In some embodiments, the outlet engagement member 240 further includes an outlet bend 244, such as Figure 17-18 As shown, the outlet curved portion 244 is adjacent to the outlet body wall portion 236 and the outlet engaging member wall 242. The outlet curved portion 244 extends outward (e.g., radially outward and axially outward, etc.) from the outlet body wall portion 236. More specifically, the outlet curved portion 244 extends along a curved path between the outlet body wall 236 and the outlet engaging member wall 242.

[0134] Aftertreatment system 100 includes an aftertreatment component cartridge 250 (e.g., cartridge, insert, etc.), also referred to herein as cartridge 250. As explained in more detail herein, inlet engagement member 220 and outlet engagement member 240 cooperate to facilitate suspension of cartridge 250 such that cartridge 250 is at least partially within inlet body 206 and / or outlet body 232. Cartridge 250 is positioned between inlet body 206 and outlet body 232. More specifically, cartridge 250 is positioned such that at least a portion of cartridge 250 is downstream of inlet body 206 and at least a portion of outlet body 232 is downstream of cartridge 250.

[0135] The after-treatment component cartridge 250 includes an after-treatment component assembly 252. The after-treatment component assembly 252 includes a housing 253 (e.g., a filter housing, etc.). The housing 253 includes a housing wall 254 (also referred to herein as a "cartridge wall") configured to house after-treatment system components. The housing 253 can be configured as a second catalyst housing 253. The housing 253 is configured to house after-treatment components therein. For example and as Figure 17 As shown, when the housing 253 is configured as a second catalyst housing 253, the second catalyst housing 253 houses a second catalyst member 256. The second catalyst member 256 is a conversion catalyst member (e.g., a selective catalytic reduction (SCR) conversion catalyst member, a catalyst metal, etc.) that helps to convert various components of the exhaust gas (e.g., nitrogen oxides (NO x ), sulfur oxides (SO x ) etc.) into other components (eg, nitrogen (N 2 ), water vapor, etc.) The housing 253 facilitates the flow of exhaust gas from the inlet body 206 into the second catalyst member 256 .

[0136] Aftertreatment component housing 253 includes an inlet portion 258 (e.g., an upstream portion). Inlet portion 258 is at least partially inserted into inlet body 106. Inlet portion 258 receives exhaust gas from inlet body 106 and provides the exhaust gas to canister 250. Aftertreatment component housing 253 also includes an outlet portion 259. Outlet portion 259 is inserted into outlet body 232. Outlet portion 259 receives exhaust gas from canister 250 and provides the exhaust gas from canister 250.

[0137] In other embodiments, component cartridge 250 includes various aftertreatment system components. The aftertreatment system components are positioned within aftertreatment component housing 253. The aftertreatment system components can treat exhaust gas generated by an internal combustion engine. In some embodiments, the aftertreatment system components reduce unwanted components (e.g., nitrogen oxides (NOx)) in the exhaust gas. x In some embodiments, aftertreatment system components facilitate the removal of particles (eg, soot, particulate matter, etc.) from the exhaust gas via a filtering member (eg, a diesel particulate filter (DPF), etc.).

[0138] In some embodiments, component cartridge 250 is not limited to housing a single aftertreatment system component. For example, component cartridge 250 may contain more than one aftertreatment system component, each of aftertreatment system components 148 being any of the embodiments described herein. In some embodiments, component cartridge 250 may contain two or more identical aftertreatment system components.

[0139] In some embodiments, after-treatment component cartridge 250 also includes a mounting pad that is substantially similar to the mounting pad.

[0140] The cartridge 250 includes an adapter 260 (e.g., a protrusion, ridge, rib, etc.). The adapter 260 is coupled to the cartridge wall 254. The adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260. Different embodiments of the adapter 260 can use different fasteners (e.g., clamps, compression connections, V-band body connections, etc.) to compress the adapter 260 and suspend the cartridge 250 within the inlet body 206 and the outlet body 232, as described in more detail herein.

[0141] In some embodiments, the adapter 260 includes an adapter wall 262 (e.g., a ring, etc.). The adapter wall 262 includes a first adapter wall portion 264 coupled to the cartridge wall 254. The first adapter wall portion 264 follows a curved path such that the first adapter wall portion 264 extends outward (e.g., radially outward) from the adapter wall 262. More specifically, an upstream portion of the first adapter wall portion 264 is substantially parallel to the direction of extension of the cartridge 250, and a downstream side of the first adapter wall portion 264 is substantially parallel to the inlet coupling flange 223.

[0142] The adapter wall 262 also includes a second adapter wall portion 265 that extends outward (e.g., radially outward) and in a downstream direction from the first adapter wall portion 264. The second adapter wall portion 265 extends along a curved path such that an upstream portion of the second adapter wall portion 265 is substantially parallel to the inlet coupling flange 223, and a downstream side of the second adapter wall portion 265 is substantially parallel to the outlet coupling flange 243. The second adapter wall portion 265 defines a first adapter engagement portion 268 (e.g., an upstream adapter engagement portion) and a second adapter engagement portion 269 (e.g., a downstream adapter engagement portion). The first adapter engagement portion 268 is configured to engage (e.g., directly through contact, or indirectly via an intermediate component, such as a sealing member, gasket, or O-ring) the inlet coupling flange 223. The second adapter engagement portion 269 is configured to engage (e.g., directly through contact, or indirectly via an intermediate component, such as a sealing member, gasket, or O-ring) the outlet coupling flange 243. By engaging the inlet coupling flange 223 and the outlet coupling flange 243 by the first adapter engaging portion 268 and the second adapter engaging portion 269, the adapter 260, the inlet engaging member 220 and the outlet engaging member 240 facilitate suspension of the cartridge 250 within the inlet body 206 and the outlet body 232 when a compressive force is applied to the adapter 260.

[0143] The adapter wall 262 also includes a third adapter wall portion 266 that extends inward (e.g., radially inward) and in a downstream direction from the second adapter wall portion 265. The third adapter wall portion 266 extends along a curved path such that an upstream portion of the third adapter wall portion 266 is substantially parallel to the outlet coupling flange 243, and a downstream side of the third adapter wall portion 266 is substantially parallel to the direction in which the cartridge 250 extends.

[0144] Thus, when compressive forces are applied to inlet and outlet engagement members 220 and 240 , compressive forces are also applied to adapter 260 , or more specifically, second adapter wall portion 265 , enabling adapter 260 to suspend cartridge 250 within inlet and outlet bodies 206 and 232 .

[0145] In some embodiments, aftertreatment system 200 includes a first gasket 246 (e.g., a gasket, seal, plug, sealing member, etc.), also referred to herein as a first sealing member. First gasket 246 can be made of a compressible material (e.g., rubber, elastomer, etc.). First gasket 246 is disposed between inlet coupling flange 223 and second adapter wall portion 265 such that first gasket 246 is separated from cartridge wall 254 by adapter 260. First gasket 246 establishes a seal between inlet coupling flange 223 and second adapter wall portion 265 (or more specifically, first adapter engagement portion 268). For example, first gasket 246 engages inlet coupling flange 223 and first adapter engagement portion 268 to form a first seal therebetween. Thus, when a compressive force is applied to inlet coupling flange 223, first gasket 246 is compressed between inlet coupling flange 223 and second adapter wall portion 265.

[0146] Similarly, aftertreatment system 200 can include a second gasket 248 (e.g., a gasket, seal, plug, sealing member, etc.), also referred to herein as a second sealing member. Second gasket 248 can be made of a compressible material (e.g., rubber, elastomer, etc.). Second gasket 248 is disposed between outlet coupling flange 243 and second adapter wall portion 265 such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a seal between outlet coupling flange 243 and second adapter wall portion 265 (or more specifically, second adapter engagement portion 269). Second gasket 248 engages outlet coupling flange 243 and second adapter wall portion 265 to form a second seal therebetween. Thus, when a compressive force is applied to outlet coupling flange 243, second gasket 248 is compressed between outlet coupling flange 243 and second adapter wall portion 265. The first and second washers 246 and 248 may be substantially similar to the first and second washers 166 and 168 , respectively.

[0147] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 18240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet coupling member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet coupling member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 223 engaging the second adapter wall portion 265. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 243 engaging the second adapter wall portion 265. The metal-to-metal seal advantageously achieves better tolerance and durability than current designs. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet coupling member 220, the outlet coupling member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0148] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 further enables the gasket compression to be controlled by the fit between the metal components and the gaskets (e.g., the first gasket 246 and / or the second gasket 248). For example, the cross-sectional space created by the fit between the metal components (e.g., the inlet engaging member 220, the outlet engaging member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gaskets (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0149] Now refer to Figures 19-34 , illustrating various embodiments of an aftertreatment system 200. In particular, the embodiments described herein relate to variations of an inlet engagement member 220, an outlet engagement member 240, and an adapter 260.

[0171] In some embodiments, when compressive force is applied to the inlet and outlet engagement members 220 and 240 , compressive force is also applied to the adapter 260 , enabling the adapter 260 to suspend the cartridge 250 within the inlet and outlet bodies 206 and 232 .

[0172] In some embodiments, when a compressive force is applied to the inlet engaging member 220 and the outlet engaging member 240, the first engaging surface 279, or more specifically, engages the adapter wall third portion 293 (or more specifically, the upstream adapter engaging surface 294a) to form a first seal therebetween, and the outlet engaging member wall third portion 286 (or more specifically, the second engaging surface 289) engages the adapter wall seventh portion 297 (or more specifically, the downstream adapter engaging surface 298a) to form a second seal between the outlet engaging member wall third portion 286 and the adapter wall seventh portion 297.

[0173] In some embodiments, Figure 19The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. First gasket 246 is disposed between inlet coupling member wall 270 (or, more specifically, inlet coupling member wall third portion 276) and adapter wall third portion 293, such that first gasket 246 is separated from cartridge wall 254 by adapter 260. First gasket 246 establishes a first seal between inlet coupling member wall 270 (or, more specifically, first engaging surface 279) and adapter wall third portion 293 (or, more specifically, upstream adapter engaging surface 294a). For example, first gasket 246 engages first engaging surface 279 and upstream adapter engaging surface 294a to form a first seal therebetween. In this manner, when a compressive force is applied to inlet coupling flange 278, first gasket 246 is compressed between inlet coupling member wall third portion 276 and adapter wall third portion 293.

[0174] Similarly, aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet coupling member wall 280 (or more specifically, outlet coupling member wall third portion 286) and adapter wall seventh portion 297, such that third gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet coupling member wall third portion 286 (or more specifically, second engaging surface 289) and adapter wall seventh portion 297 (or more specifically, downstream adapter engaging surface 298a). For example, second gasket 248 engages second engaging surface 289 and downstream adapter engaging surface 298a to form a second seal therebetween. Thus, when a compressive force is applied to outlet coupling flange 288, second gasket 248 is compressed between outlet coupling flange 288 and adapter wall eighth portion 298.

[0175] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 192 and 3. The aftertreatment system 200 may be positioned in different positions as shown. In these embodiments, the first gasket 246 may be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 may be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) may be formed by the inlet coupling flange 278 engaging the fourth adapter wall portion 294. A second seal (e.g., a metal-to-metal seal) may be formed by the outlet coupling flange 288 engaging the eighth adapter wall portion 298. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0176] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0177] Now refer to Figure 20 , shows a cross-sectional view of an aftertreatment system 200 according to another example embodiment. Figure 20In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) from the inlet body wall portion 214 .

In some embodiments, the inlet joint member wall third portion 306 is curved, such that the inlet joint member wall third portion 306 defines a curved wall portion between the inlet joint member wall second portion 304 and a downstream portion of the inlet joint member wall third portion 306, wherein the downstream portion of the inlet joint member wall third portion 306 extends along the inclined surface. The inlet joint member wall third portion 306 is adjacent to the inlet joint member wall second portion 304. In some embodiments, the inlet engagement member wall third portion 306 defines an inlet coupling flange such that the inlet coupling flange extends outwardly from the inlet body wall 214 in a downstream direction.

[0184] Outlet engaging member wall 310 includes an outlet engaging member wall third portion 316 that extends outward (e.g., axially outward) from outlet engaging member wall second portion 314 in an upstream direction. More specifically, at least a portion of outlet engaging member wall third portion 316 extends outward from outlet engaging member wall second portion 314 at a third angle relative to the direction of extension of outlet body wall 236. The third angle is defined between the direction of extension of outlet body wall 236 (e.g., dashed line 330) and an inclined plane (as indicated by dotted line 334).

[0186] The outlet engaging member wall 310 includes an outlet engaging member wall first portion 312 that extends outward (e.g., radially outward) from the outlet body wall 236 in an upstream direction. More specifically, at least a portion of the outlet engaging member wall first portion 312 extends outward from the outlet body wall 236 at a first angle relative to the direction in which the outlet body wall 236 extends. The first angle is defined between the direction in which the outlet body wall 236 extends (as indicated by dashed line 330) and an inclined plane (as indicated by dotted line 332). The outlet engaging member wall first portion 312 is continuous with the outlet body wall 236. More specifically, the downstream side of the outlet engaging member wall first portion 312 abuts the upstream side of the outlet body wall 236.

[0187] The outlet engaging member wall 310 includes an outlet engaging member wall second portion 314 that extends outward (e.g., axially outward) from the outlet engaging member wall first portion 312 in an upstream direction. More specifically, at least a portion of the outlet engaging member wall second portion 314 extends outward from the outlet engaging member wall first portion 312 at a second angle relative to the direction of extension of the outlet body wall 236.

The outlet engaging member wall third portion 316 is continuous with the outlet engaging member wall second portion 314.

[0189] The adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260. The adapter 260 includes an adapter wall 320.

[0190] The adapter wall 320 includes a first adapter wall portion 322 that extends outward (e.g., radially outward) from the cartridge wall 254 in an upstream direction. More specifically, at least a portion of the first adapter wall portion 322 extends outward from the cartridge wall 254 at a first angle relative to the direction of extension of the cartridge 250.

The first adapter wall portion 322 abuts the cartridge wall 254. More specifically, the downstream side of the first adapter wall portion 322 abuts the upstream side of the cartridge wall 254.

More specifically, at least a portion of adapter wall third portion 326 extends outward from adapter wall second portion 324 at a third angle relative to the direction of extension of barrel wall 254. As described above, the third angle is defined between the direction of extension of outlet barrel wall 254 (e.g., dashed line 330) and an inclined plane (as indicated by dotted line 334). Adapter wall third portion 326 is continuous with adapter wall second portion 324. In some embodiments, adapter wall third portion 326 defines an adapter coupling flange.

[0193] like Figure 20 As shown, the shape of outlet coupling member 240 conforms to the shape of adapter 260, such that the adapter coupling flange is disposed between inlet coupling member wall third portion 306 (e.g., the inlet coupling flange) and the outlet coupling flange. As used herein, "conform," or more specifically, "conforming shapes," refers to the arrangement of two or more components having similar shapes. For example, two shapes that conform to one another can be congruent, such that the two shapes are substantially similar in shape and size, such that corresponding surfaces of the shapes are parallel, coaxial, or otherwise similar. In other arrangements, the congruent shapes can be mirror images of one another.

[0194] In some embodiments, the upstream side of the adapter wall third portion 326 (e.g., the adapter coupling flange) defines a first adapter engagement surface 328. In some embodiments, the downstream side of the adapter wall first portion 322, the downstream side of the adapter wall second portion 324, and the downstream side of the adapter wall third portion 326 (e.g., the adapter coupling flange) cooperate to define a second adapter engagement surface 329.

[0195] In some embodiments, the upstream side of outlet engaging member wall first portion 312 , the upstream side of outlet engaging member wall second portion 314 , and the upstream side of outlet engaging member wall third portion 316 (eg, outlet coupling flange) cooperate to define an outlet engaging surface 318 .

[0196] In some embodiments, the downstream side of the inlet engaging member wall third portion 306 (eg, the inlet coupling flange) defines an inlet engaging surface 308 .

[0197] In some embodiments, when compressive force is applied to the inlet and outlet engagement members 220 and 240 , compressive force is also applied to the adapter 260 , enabling the adapter 260 to suspend the cartridge 250 within the inlet and outlet bodies 206 and 232 .

[0198] In some embodiments, the inlet engagement surface engages the first adapter engagement surface to form a first seal therebetween. In some embodiments, the outlet engagement surface engages the second adapter engagement surface to form a second seal therebetween.

[0199] In some embodiments, Figure 20 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet coupling member wall third portion 306 (e.g., the inlet coupling flange, the inlet coupling surface 308) and the upstream side (or, more specifically, the first adapter coupling surface) of the adapter wall third portion 326 (e.g., the adapter coupling flange), such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling member wall third portion 306 (e.g., the inlet coupling flange, the inlet coupling surface 308) and the upstream side (or, more specifically, the inlet coupling surface 308) of the adapter wall third portion 326 (e.g., the adapter coupling flange, the outlet coupling surface 318). For example, the first gasket 246 engages the inlet coupling flange and the first adapter coupling surface 328 to form a first seal therebetween. In this manner, when a compressive force is applied to the inlet engaging member wall third portion 306 , the first gasket 246 is compressed between the inlet engaging member wall third portion 306 and the adapter wall third portion 326 .

[0200] Similarly, aftertreatment system 200 can include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between the upstream side of outlet-joining member wall third portion 316 (e.g., outlet coupling flange, outlet joining surface 318) and the downstream side of adapter wall third portion 326 (e.g., adapter coupling flange), such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet-joining member wall third portion 316 (e.g., outlet coupling flange) and the downstream side of adapter wall third portion 326 (e.g., adapter coupling flange). For example, second gasket 248 engages outlet-joining member wall third portion 316 and adapter coupling flange to form a second seal therebetween. In this manner, when a compressive force is applied to outlet-joining member wall third portion 316, second gasket 248 is compressed between outlet-joining member wall third portion 316 and second adapter wall third portion 326.

[0201] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 202. In different positions as shown. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet joint member wall third portion 306 engaging the adapter wall third portion 326. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet joint member wall third portion 316 engaging the second adapter wall third portion 326. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0202] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0203] Figure 21 is a cross-sectional view of an aftertreatment system 200 according to another example embodiment. Figure 21 In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) and in a downstream direction from the inlet body wall portion 214 . The inlet engagement member 220 includes an inlet engagement member wall 340 .

The inlet engaging member wall 340 is adjacent to the inlet body wall 214.

[0205] The inlet engaging member wall 340 includes an inlet engaging member wall first surface 342 (e.g., an outer surface, an inlet engaging member wall outer surface) extending along an inclined surface. The inlet engaging member wall 340 also includes an inlet engaging member wall second surface 344 (e.g., an inner surface, an inlet engaging member wall inner surface) extending substantially parallel to the direction in which the inlet body 206 extends. The inlet engaging member wall 340 also includes an inlet engaging member wall third surface 346 (e.g., a radial surface, an inlet engaging member wall radial surface) extending in a radial direction substantially perpendicular to the direction in which the inlet body 206 and / or the inlet engaging member wall second surface 344 extend.

[0206] The inlet coupling member 220 also includes an inlet coupling flange 348 that extends outward (e.g., axially outward) in a downstream direction from the inlet coupling member wall 340.

The inlet coupling flange 348 abuts the inlet coupling member wall 340.

[0207] The outlet body 232 includes an outlet engaging member 240 positioned upstream of the outlet body wall 236 and flaring or extending outward (eg, radially outward, axially outward, etc.) and in an upstream direction from the outlet body wall 236 .

[0208] The outlet engaging member wall 350 extends outward from the outlet body wall 236. At least a portion of the outlet engaging member wall 350 extends along an inclined surface from the outlet body wall 236. The inclined surface is angled relative to the direction in which the outlet body 232 extends. The angle is between 15° and 90° relative to the direction in which the outlet body 232 extends. The outlet engaging member wall 350 abuts the outlet body wall 236.

[0209] The outlet engaging member wall 350 includes an outlet engaging member wall first surface 352 (e.g., an outer surface, outlet engaging member wall outer surface) extending along an inclined surface. The outlet engaging member wall 350 also includes an outlet engaging member wall second surface 354 (e.g., an inner surface, outlet engaging member wall inner surface) extending substantially parallel to the direction in which the outlet body 232 extends. The outlet engaging member wall 350 also includes an outlet engaging member wall third surface 356 (e.g., a radial surface, outlet engaging member wall radial surface) extending in a radial direction substantially perpendicular to the direction in which the outlet body 232 and / or the outlet engaging member wall second surface 354 extend.

[0210] The outlet coupling member wall 350 further includes an outlet coupling flange 358 extending outwardly (e.g., axially outwardly) in an upstream direction from the outlet coupling member wall 350. More specifically, the outlet coupling flange 358 extends in an upstream direction away from the outlet coupling member wall third surface 356. The outlet coupling flange 358 abuts the outlet coupling member wall 350.

[0211] like Figure 21 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0212] Adapter 260 includes a base 360 ​​that extends outward from barrel wall 254 such that at least a portion of base 360 ​​extends upstream of barrel wall 254. In some embodiments, base 360 ​​is attached to an outer surface of barrel wall 254. In some embodiments, base 360 ​​is integrally formed with barrel wall 254. In some embodiments, base 360 ​​is substantially parallel to barrel wall 254 or coaxial with barrel wall 254.

[0213] Adapter 260 also includes a protrusion 362 extending radially outward from base 360. In some embodiments, protrusion 362 is substantially perpendicular to base 360. In some embodiments, protrusion 362 is disposed between inlet coupling flange 348 and outlet coupling flange 358. Protrusion 362 includes a first engagement side 364 (e.g., an upstream side). Protrusion 362 also includes a second engagement side 366 (e.g., a downstream side).

[0214] In some embodiments, first engagement side 364 of protrusion 362 engages inlet coupling flange 348. In some embodiments, the engagement of first engagement side 364 of protrusion 362 with inlet coupling flange 348 forms a first seal between first engagement side 364 of protrusion 362 and inlet coupling flange 348. In some embodiments, second engagement side 366 of protrusion 362 engages outlet coupling flange 358. In some embodiments, the engagement of second engagement side 366 of protrusion 362 with outlet coupling flange 358 forms a second seal between second engagement side 366 of protrusion 362 and outlet coupling flange 358.

[0215] In some embodiments, Figure 21 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet member wall 340 (or more specifically, the inlet member wall third surface 346) and a first engaging side 364 of a protrusion 362, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet member wall third surface 346 and the first engaging side 364 of the protrusion 362. For example, the first gasket 246 engages the inlet member wall third surface 346 and the first engaging side 364 of the protrusion 362 to form a first seal therebetween. In this manner, when a compressive force is applied to the inlet member wall 340, the first gasket 246 is compressed between the inlet member wall third surface 346 and the first engaging side 364 of the protrusion 362.

[0216] Similarly, aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet engaging member wall 350 (or more specifically, outlet engaging member wall third surface 356) and second engaging side 366 of protrusion 362, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet engaging member wall third surface 356 and second engaging side 366 of protrusion 362. For example, second gasket 248 engages outlet engaging member wall third surface 356 and second engaging side 366 of protrusion 362 to form a second seal therebetween. In this manner, when a compressive force is applied to outlet engaging member wall 350, second gasket 248 is compressed between outlet engaging member wall third surface 356 and second engaging side 366 of protrusion 362.

[0217] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 21240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 348 engaging the first engaging side 364 of the protrusion 362. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 358 engaging the second engaging side 366 of the protrusion 362. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0218] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0219] Figure 22 is a cross-sectional view of an aftertreatment system 200 according to another example embodiment. Figure 22In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) and in a downstream direction from the inlet body wall portion 214 . The inlet engagement member 220 includes an inlet engagement member wall 400 .

[0220] The inlet engaging member wall 400 extends outward from the inlet body wall 214.

The inlet engaging member wall 400 also includes an inlet engaging member wall second surface 404 (e.g., an inner surface, an inlet engaging member wall inner surface) that extends substantially parallel to the direction of extension of the inlet body 206. In some embodiments, the inlet engaging member wall second surface 404 is spaced radially outward from the inlet body wall 214. The inlet engaging member wall 400 also includes an inlet engaging member wall third surface 406 (e.g., a radial surface, an inlet engaging member wall radial surface) that extends in a radial direction substantially perpendicular to the direction of extension of the inlet body 206 and / or the inlet engaging member wall second surface 404.

[0222] The inlet coupling member 220 further includes an inlet coupling flange 408 that extends outward (e.g., axially outward) in a downstream direction from the inlet coupling member wall 400. More specifically, the inlet coupling flange 408 extends in a downstream direction away from the inlet coupling member wall third surface 406. The inlet coupling flange 408 abuts the inlet coupling member wall 400.

[0223] The outlet body 232 includes an outlet engaging member 240 positioned upstream of the outlet body wall 236 and flaring or extending outward (eg, radially outward, axially outward, etc.) and in an upstream direction from the outlet body wall 236 . The outlet engaging member 240 includes an outlet engaging member wall 410 .

[0224] The outlet engaging member wall 410 extends outward from the outlet body wall 236.

The inclined surface is angled relative to the direction in which the outlet body 232 extends. The angle is between 15° and 90° relative to the direction in which the outlet body 232 extends. In other embodiments, at least a portion of the outlet engaging member wall 410 extends from the outlet body wall 236 along a curved path. The outlet engaging member wall 410 abuts the outlet body wall 236.

[0225] The outlet engaging member wall 410 includes an outlet engaging member wall first surface 412 (e.g., an outer surface) that extends along an inclined and / or curved path. The outlet engaging member wall 410 also includes an outlet engaging member wall second surface 414 (e.g., an inner surface) that extends substantially parallel to the direction in which the outlet body 232 extends. In some embodiments, the outlet engaging member wall second surface 414 is spaced radially outward from the outlet body wall 236. The outlet engaging member wall 410 also includes an outlet engaging member wall third surface 416 (e.g., a radial surface) that extends in a radial direction that is substantially perpendicular to the direction in which the outlet body 232 and / or the outlet engaging member wall second surface 414 extend.

[0226] The outlet coupling member wall 350 further includes an outlet coupling flange 418 extending outwardly (e.g., axially outwardly) in an upstream direction from the outlet coupling member wall 410. More specifically, the outlet coupling flange 418 extends in an upstream direction away from the outlet coupling member wall third surface 416. The outlet coupling flange 418 abuts the outlet coupling member wall 410.

[0227] like Figure 22 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0228] Adapter 260 includes a base 420 that is substantially parallel to and / or coaxial with barrel wall 254. In some embodiments, base 420 is coupled to barrel wall 254. In other embodiments, base 420 is integrally formed with barrel wall 254. In some embodiments, at least a portion of base 420 is disposed outward (e.g., radially outward) from barrel wall 254. In some embodiments, base 360 ​​is attached to an outer surface (e.g., a radially outer surface) of barrel wall 254.

[0229] Adapter 260 also includes a coupling portion 422 extending radially outward from base 420. In some embodiments, coupling portion 422 is substantially perpendicular to base 420. In some embodiments, coupling portion 422 is disposed between inlet coupling flange 408 and outlet coupling flange 418. Coupling portion 422 includes a first engagement side 424 (e.g., an upstream side). Coupling portion 422 also includes a second engagement side 426 (e.g., a downstream side). In some embodiments, coupling portion 422 extends outward from the center (e.g., the axial center) of base 420.

[0230] In some embodiments, first engagement side 424 of coupling portion 422 engages inlet coupling flange 408. In some embodiments, the engagement of first engagement side 424 of coupling portion 422 with inlet coupling flange 408 forms a first seal between first engagement side 424 of coupling portion 422 and inlet coupling flange 408. In some embodiments, second engagement side 426 of coupling portion 422 engages outlet coupling flange 418. In some embodiments, the engagement of second engagement side 426 of coupling portion 422 with outlet coupling flange 418 forms a second seal between second engagement side 426 of coupling portion 422 and outlet coupling flange 418.

[0231] In some embodiments, Figure 22 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet member wall 400 (or more specifically, the inlet member wall third surface 406) and the first engaging side 424 of the coupling portion 422, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet member wall third surface 406 and the first engaging side 424 of the coupling portion 422. For example, the first gasket 246 engages the inlet member wall third surface 406 and the first engaging side 424 of the coupling portion 422 to form a first seal therebetween. In this manner, when a compressive force is applied to the inlet member wall 400, the first gasket 246 is compressed between the inlet member wall third surface 406 and the first engaging side 424 of the coupling portion 422.

[0232] Similarly, aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet engaging member wall 410 (or more specifically, outlet engaging member wall third surface 416) and second engaging side 426 of coupling portion 422, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet engaging member wall third surface 416 and second engaging side 426 of coupling portion 422. For example, second gasket 248 engages outlet engaging member wall third surface 416 and second engaging side 426 of coupling portion 422 to form a second seal therebetween. In this manner, when a compressive force is applied to outlet engaging member wall 410, second gasket 248 is compressed between outlet engaging member wall third surface 416 and second engaging side 426 of coupling portion 422.

[0233] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 22 240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 408 engaging the first joint side 424 of the coupling portion 422. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 418 engaging the second joint side 426 of the coupling portion 422. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0234] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0235] Now refer to Figure 23 and Figure 24 , shows a cross-sectional view of an aftertreatment system 200 according to various example embodiments. Figure 23 and Figure 24 In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) from the inlet body wall portion 214 . The inlet engagement member 220 includes an inlet engagement member wall 450 .

[0236] The inlet engaging member wall 450 includes an inlet engaging member wall first portion 452 that extends outwardly from and substantially parallel to the inlet body wall 214.

More specifically, the inlet engaging member wall second curved portion 455 extends along a curved path between the inlet engaging member wall first portion 452 and the inlet coupling flange 454.

[0238] The outlet engaging member 240 is upstream of the outlet body wall portion 236 and flares or extends outwardly (eg, radially outwardly, axially outwardly, etc.) from the outlet body wall portion 236 . The outlet engaging member 240 includes an outlet engaging member wall 460 .

[0239] The outlet engaging member wall 460 includes an outlet engaging member wall first portion 462 that extends outwardly from and substantially parallel to the outlet body wall 236.

The outlet engaging member wall first curved portion 463 is adjacent to the outlet body wall 236 and adjacent to the outlet engaging member wall first portion 462. The outlet engaging member wall first curved portion 463 extends outward (e.g., radially outward and axially outward, etc.) from the outlet body wall 236. More specifically, the outlet engaging member wall first curved portion 463 extends along a curved path between the outlet body wall 236 and the outlet engaging member wall first portion 462.

[0240] The outlet joint member wall 460 includes an outlet joint member wall second portion, referred to herein as an outlet coupling flange 464. The outlet coupling flange 464 extends outwardly (e.g., radially outwardly) from the outlet joint member wall first portion 462.

The inclined surface is angled relative to the direction in which the outlet joint member wall first portion 462 and / or the outlet body wall 236 extend. In some embodiments, the inclined surface is between 15° and 90° relative to the direction in which the outlet joint member wall first portion 462 and / or the outlet body wall 236 extend. In some embodiments, the outlet coupling flange 464 is adjacent to the outlet joint member wall first portion 462. In other embodiments, and as Figure 23 and Figure 24 As shown, the outlet coupling flange 464 includes an outlet coupling member wall second curved portion 465. The outlet coupling member wall second curved portion 465 is adjacent to the outlet coupling member wall first portion 462 and adjacent to the outlet coupling flange 464. The outlet coupling member wall second curved portion 465 extends outward (e.g., radially outward and axially outward, etc.) from the outlet coupling member wall first portion 462. More specifically, the outlet coupling member wall second curved portion 465 extends along a curved path between the outlet coupling member wall first portion 462 and the outlet coupling flange 464.

[0241] like Figure 23 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0242] The adapter 260 includes an adapter wall 470 (e.g., a ring, etc.). The adapter wall 470 includes an adapter wall first portion 472. In some embodiments, the adapter wall first portion 472 is coupled to the barrel wall 254. In other embodiments, the adapter wall first portion 472 is integrally formed with the barrel wall 254. The adapter wall first portion 472 extends outward (e.g., radially outward) from the barrel wall 254.

[0243] Adapter wall 470 also includes an adapter wall second portion 474 that extends outward (e.g., radially outward, axially outward) and in a downstream direction from adapter wall first portion 472. Adapter wall second portion 474 is adjacent to adapter wall first portion 472. A flat portion of adapter wall second portion 474 extends along an inclined surface that is angled relative to adapter wall first portion 472. The angle of the inclined surface relative to the direction in which adapter wall first portion 472 extends is between 15° and 90°. In some embodiments, adapter wall second portion 474 is substantially parallel to inlet coupling flange 454.

[0244] The adapter wall 470 includes an adapter wall third portion 476. In some embodiments, the adapter wall third portion 476 is coupled to the barrel wall 254. In other embodiments, the adapter wall third portion 476 is integrally formed with the barrel wall 254.

The adapter wall third portion 476 is positioned downstream of the adapter wall first portion 472.

[0245] Adapter wall 470 also includes an adapter wall fourth portion 478 that extends outward (e.g., radially outward, axially outward) from adapter wall fourth portion 478 and in an upstream direction. Adapter wall fourth portion 478 abuts adapter wall third portion 476. A flat portion of adapter wall fourth portion 478 extends along an inclined surface that is angled relative to adapter wall third portion 476. The angle of the inclined surface relative to the direction in which adapter wall third portion 476 extends is between 90° and 180°.

[0246] Adapter wall 470 also includes an adapter wall fifth portion 479 extending between adapter wall second portion 474 and adapter wall fourth portion 478. More specifically, adapter wall fifth portion 479 extends outward (e.g., radially outward, axially outward) and in a downstream direction from adapter wall second portion 474 toward the apex, and extends inward (e.g., radially inward) in a downstream direction from the apex toward adapter wall fourth portion 478. Adapter wall fifth portion 479 is contiguous with adapter wall second portion 474 and adapter wall fourth portion 478.

[0247] In some embodiments, when compressive force is applied to the inlet and outlet engagement members 220 and 240 , compressive force is also applied to the adapter 260 , enabling the adapter 260 to suspend the cartridge 250 within the inlet and outlet bodies 206 and 232 .

[0248] In some embodiments, when a compressive force is applied to the inlet coupling member 220 and the outlet coupling member 240, the inlet coupling flange 454 engages the adapter wall second portion 474 to form a first seal between the inlet coupling flange 454 and the adapter wall second portion 474. The outlet coupling flange 464 engages the adapter wall fourth portion 478 to form a second seal between the outlet coupling flange 464 and the adapter wall fourth portion 478.

[0249] In some embodiments, Figure 23 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet coupling flange 454 and the adapter wall second portion 474, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling flange 454 and the adapter wall second portion 474. For example, the first gasket 246 engages the inlet coupling flange 454 and the adapter wall second portion 474 to form a first seal therebetween. Thus, when a compressive force is applied to the inlet coupling flange 454, the first gasket 246 is compressed between the inlet coupling flange 454 and the adapter wall second portion 474.

[0250] Similarly, aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet coupling flange 464 and fourth adapter wall portion 478, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet coupling flange 464 and fourth adapter wall portion 478. For example, second gasket 248 engages outlet coupling flange 464 and fourth adapter wall portion 478 to form a second seal therebetween. Thus, when a compressive force is applied to outlet coupling flange 464, second gasket 248 is compressed between outlet coupling flange 464 and fourth adapter wall portion 478.

[0251] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 23 240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet engaging member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet engaging member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 454 engaging the adapter wall second portion 474. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 464 engaging the adapter wall fourth portion 478. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0252] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0253] like Figure 24 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0254] The adapter 260 includes a base 490 that extends outwardly from the barrel wall 254. In some embodiments, the base 490 is attached to the outer surface of the barrel wall 254. In some embodiments, the base 490 is integrally formed with the barrel wall 254. In some embodiments, the base 490 is substantially parallel to the barrel wall 254 or coaxial with the barrel wall 254.

[0255] Adapter 260 also includes a protrusion 492 extending radially outward from base 490. In some embodiments, protrusion 492 is substantially perpendicular to base 490. In some embodiments, protrusion 492 is disposed between inlet coupling flange 454 and outlet coupling flange 464. Protrusion 492 includes a first engagement side (e.g., upstream side) 494. Protrusion 492 also includes a second engagement side (e.g., downstream side) 496.

[0256] In some embodiments, first engagement side 494 engages inlet coupling flange 454. In some embodiments, the engagement of first engagement side 494 with inlet coupling flange 454 forms a first seal between first engagement side 494 and inlet coupling flange 454. In some embodiments, second engagement side 496 engages outlet coupling flange 464. In some embodiments, the engagement of second engagement side 496 with outlet coupling flange 464 forms a second seal between second engagement side 496 and outlet coupling flange 464.

[0257] In some embodiments, Figure 24 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet coupling flange 454 and the first engaging side 494, such that the first gasket 246 is separated from the barrel wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling flange 454 and the first engaging side 494. For example, the first gasket 246 engages the inlet coupling flange 454 and the first engaging side 494 to form a first seal therebetween. Thus, when a compressive force is applied to the inlet coupling flange 454, the first gasket 246 is compressed between the inlet coupling flange 454 and the first engaging side 494.

[0258] Similarly, aftertreatment system 200 can include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet coupling flange 464 and second engaging side 496, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet coupling flange 464 and second engaging side 496. For example, second gasket 248 engages outlet coupling flange 464 and second engaging side 496 to form a second seal therebetween. Thus, when a compressive force is applied to outlet coupling flange 464, second gasket 248 is compressed between outlet coupling flange 464 and second engaging side 496.

[0259] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 24240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 454 engaging the first joint side 494. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 464 and the second joint side 496. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0260] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

The inlet coupling flange 504 extends along an inclined surface that is angled relative to the inlet joint member wall first portion 502. The inclined surface is angled relative to the direction in which the inlet joint member wall first portion 502 and / or the inlet body wall 214 extend. In some embodiments, the inclined surface is between 15° and 90° relative to the direction in which the inlet joint member wall first portion 502 and / or the inlet body wall 214 extend.

More specifically, the outlet engaging member wall first curved portion 513 extends along a curved path between the outlet body wall 236 and the outlet engaging member wall first portion 512.

[0267] The outlet joint member wall 510 includes an outlet joint member wall second portion, referred to herein as an outlet coupling flange 514. The outlet coupling flange 514 extends outwardly (e.g., radially outwardly) from the outlet joint member wall first portion 512. The outlet coupling flange 514 extends along an inclined surface that is angled relative to the outlet joint member wall first portion 512. The inclined surface is angled relative to the direction in which the outlet joint member wall first portion 512 and / or the outlet body wall 236 extend. In some embodiments, the inclined surface is between 15° and 90° relative to the direction in which the outlet joint member wall first portion 512 and / or the outlet body wall 236 extend. Figure 25 As shown, the outlet coupling flange 514 is substantially perpendicular to the outlet engaging member wall first portion 512 (eg, the angle of the bevel is 90°).

[0269] like Figure 25 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0270] The adapter 260 includes a base 520 that extends outward from the barrel wall 254. In some embodiments, the base 520 is attached to the outer surface of the barrel wall 254.

[0272] exist Figure 25 In the illustrated embodiment, the aftertreatment system 200 includes an engagement member 530 . The engagement member 530 includes an engagement member body 532 .

[0273] The engaging member body 532 defines a first recess 534 that is configured to receive the inlet coupling flange 504. In some embodiments, when the first recess 534 receives the inlet coupling flange 504, the inlet coupling flange 504 engages the engaging member body 532 at the first recess 534 to form a first seal between the first recess 534 and the inlet coupling flange 504.

[0274] The engaging member body 532 defines a second recess 536 configured to receive the protrusion 522. In some embodiments, when the second recess 536 receives the protrusion 522, the protrusion 522 engages the engaging member body 532 at the second recess 536 to form a first seal therebetween.

[0276] In some embodiments, Figure 25 The aftertreatment system 200 shown includes a first gasket 246 and / or a second gasket 248, also referred to herein as a first sealing member and a second sealing member, respectively. The first gasket 246 and / or the second gasket 248 are disposed between the joint member body 532 and the base 520 such that the first gasket 246 and / or the second gasket 248 are separated from the barrel wall 254 by the base 520. The first gasket 246 and / or the second gasket 248 establish a first seal and / or a second seal, respectively, between the joint member body 532 and the base 520. For example, the first gasket 246 and / or the second gasket 248 engage the joint member body 532 and the base 520 to form a first seal and / or a second seal between the joint member body 532 and the base 520. In this manner, when a compressive force is applied to the joint member 530, the first gasket and / or the second gasket 248 are compressed between the joint member body 532 and the base 520.

[0277] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 25530 . In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248 . In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the protrusion 522 engaging the joint member body 532 at the second recess 536 . A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 514 engaging the joint member body 532 at the third recess 538 . Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248 , the number of components in the connection created by the inlet joint member 220 , the outlet joint member 240 , and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet joint member 220 and the joint member 530 , the metal-to-metal contact between the outlet joint member 240 and the joint member 530 , and / or the metal-to-metal contact between the adapter 260 and the joint member 530 also reduces gasket creep.

[0278] In some embodiments, the metal-to-metal contact between the inlet joint member 220 and the joint member 530, the metal-to-metal contact between the outlet joint member 240 and the joint member 530, and / or the metal-to-metal contact between the adapter 260 and the joint member 530 does not form a seal therebetween. In some embodiments, the metal-to-metal contact between the inlet joint member 220 and the joint member 530, the metal-to-metal contact between the outlet joint member 240 and the joint member 530, and / or the metal-to-metal contact between the adapter 260 and the joint member 530 provides an alternative path for external forces to pass through the connection created by the inlet joint member 220, the outlet joint member 240, the adapter 260, and the joint member 530. Advantageously, the metal-to-metal contact between the inlet joint member 220 and the joint member 530, the metal-to-metal contact between the outlet joint member 240 and the joint member 530, and / or the metal-to-metal contact between the adapter 260 and the joint member 530 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet joint member 220 and the joint member 530, the metal-to-metal contact between the outlet joint member 240 and the joint member 530, and / or the metal-to-metal contact between the adapter 260 and the joint member 530 can also control the gasket compression by the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet joint member 220, the outlet joint member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0290] The adapter 260 includes a base 560 that extends outward from the barrel wall 254. In some embodiments, the base 560 is attached to the outer surface of the barrel wall 254. In some embodiments, the base 560 is integrally formed with the barrel wall 254. In some embodiments, the base 560 is substantially parallel to the barrel wall 254 or coaxial with the barrel wall 254.

[0291] Adapter 260 also includes a protrusion 562 extending radially outward from base 560. In some embodiments, protrusion 562 is substantially perpendicular to base 560. In some embodiments, protrusion 562 is disposed between inlet coupling flange 548 and outlet coupling flange 558. Protrusion 562 defines a first recess 564 (e.g., an upstream recess). Protrusion 562 also includes a second recess 566 (e.g., a downstream recess).

[0292] In some embodiments, the shape of the inlet engaging member wall 540 conforms to the shape of the upstream side of the protrusion 562. More specifically, the first recess 564 is sized to receive at least a portion of the inlet engaging member wall 540 such that the portion of the inlet engaging member wall 540 engages the protrusion 562 at the first recess 564. In some embodiments, the engagement of the portion of the inlet engaging member wall 540 with the protrusion 562 at the first recess 564 forms a first seal between the portion of the inlet engaging member wall 540 and the protrusion 562.

[0293] In some embodiments, the inlet coupling flange 548 engages at least a portion of the upstream side of the protrusion 562 and forms a seal between the inlet coupling flange 548 and the upstream side of the protrusion 562. In other embodiments, Figure 26 and Figure 27 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. Figure 26As shown, the first gasket 246 is disposed between the inlet coupling flange 548 and the upstream side of the protrusion 562, such that the first gasket 246 is separated from the barrel wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling flange 548 and the upstream side of the protrusion 562. For example, the first gasket 246 engages the inlet coupling flange 548 and the upstream side of the protrusion 562 to form a first seal between the inlet coupling flange 548 and the upstream side of the protrusion 562. Thus, when a compressive force is applied to the inlet coupling flange 548, the first gasket 246 is compressed between the inlet coupling flange 548 and the upstream side of the protrusion 562. In other embodiments and as shown in FIG. Figure 27 As shown, the first gasket 246 is disposed between the inlet engaging member wall 540 and the upstream side of the protrusion 562, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet engaging member wall 540 and the upstream side of the protrusion 562. For example, the first gasket 246 engages the inlet engaging member wall 540 and the upstream side of the protrusion 562 to form a first seal between the inlet engaging member wall 540 and the upstream side of the protrusion 562. In this manner, when a compressive force is applied to the inlet engaging member wall 540, the first gasket 246 is compressed between the inlet engaging member wall 540 and the upstream side of the protrusion 562.

[0294] In some embodiments, the shape of the outlet engaging member wall 550 conforms to the shape of the downstream side of the protrusion 562. More specifically, the second recess 566 is sized to receive at least a portion of the outlet engaging member wall 550 such that the portion of the outlet engaging member wall 550 engages the protrusion 562 at the second recess 566. In some embodiments, the engagement of the portion of the outlet engaging member wall 550 with the protrusion 562 at the second recess 566 forms a second seal between the portion of the outlet engaging member wall 550 and the protrusion 562.

[0295] In some embodiments, the outlet coupling flange 558 engages at least a portion of the downstream side of the protrusion 562 and forms a seal between the outlet coupling flange 558 and the downstream side of the protrusion 562. In other embodiments, the aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. In some embodiments and as Figure 26As shown, the second gasket 248 is disposed between the outlet coupling flange 558 and the downstream side of the protrusion 562, such that the second gasket 248 is separated from the barrel wall 254 by the adapter 260. The second gasket 248 establishes a second seal between the outlet coupling flange 558 and the downstream side of the protrusion 562. For example, the second gasket 248 engages the outlet coupling flange 558 and the downstream side of the protrusion 562 to form a second seal between the outlet coupling flange 558 and the downstream side of the protrusion 562. Thus, when a compressive force is applied to the outlet coupling flange 558, the second gasket 248 is compressed between the outlet coupling flange 558 and the downstream side of the protrusion 562. In other embodiments and as shown, Figure 27 As shown, the second gasket 248 is disposed between the outlet engaging member wall 550 and the downstream side of the protrusion 562, such that the second gasket 248 is separated from the cartridge wall 254 by the adapter 260. The second gasket 248 establishes a second seal between the outlet engaging member wall 550 and the downstream side of the protrusion 562. For example, the second gasket 248 engages the outlet engaging member wall 550 and the downstream side of the protrusion 562 to form a second seal between the outlet engaging member wall 550 and the downstream side of the protrusion 562. In this manner, when a compressive force is applied to the outlet engaging member wall 550, the second gasket 248 is compressed between the outlet engaging member wall 550 and the upstream side of the protrusion 562.

[0296] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 26 and Figure 27 56. In various embodiments, the aftertreatment system 200 may include the first gasket 246 and / or the second gasket 248 ... second gasket 248 and / or the second gasket 2 In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0297] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0298] Now refer to Figure 28 and Figure 29 , shows a cross-sectional view of an aftertreatment system 200 according to various example embodiments. Figure 28 and Figure 29 In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) from the inlet body wall portion 214 .

[0307] The outlet coupling flange 616 extends along an angled surface relative to the outlet engaging member wall second portion 614. The angle of the angled surface relative to the direction of extension of the outlet engaging member wall second portion 614 is between 15° and 90°. The outlet coupling flange 616 defines a second engaging surface, which is described in more detail herein. In some embodiments, the outlet coupling flange 616 abuts the outlet engaging member wall second portion 614. In other embodiments, and as Figure 28 and Figure 29 As shown, the outlet coupling flange 616 includes an outlet coupling member wall third curved portion 617.

More specifically, the outlet coupling member wall third curved portion 617 extends along a curved path between the outlet coupling member wall second portion 614 and the outlet coupling flange 616.

[0308] like Figure 28 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0309] The adapter 260 includes a base 620 that extends outward from the barrel wall 254. In some embodiments, the base 620 is attached to the outer surface of the barrel wall 254. In some embodiments, the base 620 is integrally formed with the barrel wall 254. In some embodiments, the base 620 is substantially parallel to the barrel wall 254 or coaxial with the barrel wall 254.

[0310] Adapter 260 also includes a protrusion 622 extending radially outward from base 620. In some embodiments, protrusion 622 is substantially perpendicular to base 620. In some embodiments, protrusion 622 is disposed between inlet coupling flange 606 and outlet coupling flange 616. Protrusion 622 includes a first engagement side (e.g., upstream side) 624. Protrusion 622 also includes a second engagement side (e.g., downstream side) 626.

[0311] In some embodiments, the first engaging side 624 engages the inlet coupling flange 606. In some embodiments, the engagement of the first engaging side 624 with the inlet coupling flange 606 forms a first seal between the first engaging side 624 and the inlet coupling flange 606. In some embodiments, the second engaging side 626 engages the outlet coupling flange 616. In some embodiments, the engagement of the second engaging side 626 with the outlet coupling flange 616 forms a second seal between the second engaging side 626 and the outlet coupling flange 616.

[0312] In some embodiments, Figure 28 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet engaging member wall 600 and the first engaging side 624, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet engaging member wall 600 and the first engaging side 624. For example, the first gasket 246 engages the inlet engaging member wall 600 and the first engaging side 624 to form a first seal therebetween. In this manner, when a compressive force is applied to the inlet engaging member wall 600, the first gasket 246 is compressed between the inlet engaging member wall 600 and the first engaging side 624.

[0313] Similarly, the aftertreatment system 200 can include a second gasket 248, also referred to herein as a second sealing member. The second gasket 248 is disposed between the outlet joint member wall 610 and the second joint side 626, such that the second gasket 248 is separated from the cartridge wall 254 by the adapter 260. The second gasket 248 establishes a second seal between the outlet joint member wall 610 and the second joint side 626. For example, the second gasket 248 engages the outlet joint member wall 610 and the second joint side 626 to form a second seal therebetween. In this manner, when a compressive force is applied to the outlet joint member wall 610, the second gasket 248 is compressed between the outlet joint member wall 610 and the second joint side 626.

[0314] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 28 240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 606 engaging the first joint side 624. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 616 engaging the second joint side 626. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0315] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0316] like Figure 29 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0317] The adapter 260 includes an adapter wall 630 (e.g., a ring, etc.). The adapter wall 630 includes an adapter wall first portion 632. In some embodiments, the adapter wall first portion 632 is coupled to the barrel wall 254. In other embodiments, the adapter wall first portion 632 is integrally formed with the barrel wall 254.

In some embodiments, the flat portion of the adapter wall third portion 636 is substantially parallel to the inlet coupling flange 606. In some embodiments, the adapter wall third portion 636 defines a first engagement surface 638 (e.g., an upstream engagement surface).

[0320] The adapter wall 630 includes an adapter wall fourth portion 642. In some embodiments, the adapter wall fourth portion 642 is coupled to the barrel wall 254. In other embodiments, the adapter wall fourth portion 642 is integrally formed with the barrel wall 254.

[0321] Adapter wall 630 also includes an adapter wall fifth portion 644 that extends outward (e.g., radially outward, axially outward) and in an upstream direction from adapter wall fourth portion 642. Adapter wall fifth portion 644 is adjacent to adapter wall fourth portion 642. A flat portion of adapter wall fifth portion 644 extends along an inclined surface that is angled relative to adapter wall fourth portion 642. The angle of the inclined surface relative to the direction of extension of adapter wall fourth portion 642 is between 15° and 90°.

[0322] Adapter wall 630 includes a sixth adapter wall portion 646. In some embodiments, sixth adapter wall portion 646 extends outward (e.g., radially outward, axially outward) from fifth adapter wall portion 644 and in a downstream direction. Sixth adapter wall portion 646 abuts fifth adapter wall portion 644. A flat portion of sixth adapter wall portion 646 extends along an angled surface relative to fifth adapter wall portion 644. The angle of the angled surface relative to the direction of extension of fifth adapter wall portion 644 is between 15° and 90°. In some embodiments, the flat portion of sixth adapter wall portion 646 is substantially parallel to outlet coupling flange 616. In some embodiments, sixth adapter wall portion 646 defines a second engagement surface 648 (e.g., a downstream engagement surface).

[0323] Adapter wall 290 also includes an adapter wall seventh portion 640 extending between adapter wall third portion 636 and adapter wall sixth portion 646. More specifically, adapter wall seventh portion 640 extends outward (e.g., radially outward, axially outward) and in a downstream direction from adapter wall third portion 636 toward the apex, and extends inward (e.g., radially inward) in a downstream direction from the apex toward adapter wall sixth portion 646. Adapter wall seventh portion 640 is contiguous with adapter wall third portion 636 and adapter wall sixth portion 646.

[0324] In some embodiments, when compressive force is applied to the inlet and outlet engagement members 220 and 240 , compressive force is also applied to the adapter 260 , enabling the adapter 260 to suspend the cartridge 250 within the inlet and outlet bodies 206 and 232 .

[0325] In some embodiments, when a compressive force is applied to the inlet coupling member 220 and the outlet coupling member 240, the inlet coupling flange 606 engages the first engaging surface 638 to form a first seal between the inlet coupling flange 606 and the first engaging surface 638. The outlet coupling flange 616 engages the second engaging surface 648 to form a second seal between the outlet coupling flange 616 and the second engaging surface 648.

[0326] In some embodiments, Figure 29The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet-joining member wall 600 and the adapter wall second portion 634, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet-joining member wall 600 and the adapter wall second portion 634. For example, the first gasket 246 engages the inlet-joining member wall 600 and the adapter wall second portion 634 to form a first seal therebetween. In this manner, when a compressive force is applied to the inlet-joining member wall 600, the first gasket 246 is compressed between the inlet-joining member wall 600 and the adapter wall second portion 634.

[0327] Similarly, aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet engagement member wall 610 and adapter wall fifth portion 644, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet engagement member wall 610 and adapter wall fifth portion 644. For example, second gasket 248 engages outlet engagement member wall 610 and adapter wall fifth portion 644 to form a second seal therebetween. In this manner, when a compressive force is applied to outlet engagement member wall 610, second gasket 248 is compressed between outlet engagement member wall 610 and adapter wall fifth portion 644.

[0328] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 2960 . In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 606 engaging the first joint surface 638. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 616 engaging the second joint surface 648. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0329] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0338] like Figure 30 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0339] The adapter 260 includes an adapter wall 670 (e.g., a ring, etc.). The adapter wall 670 includes an adapter wall first portion 672.

[0344] In some embodiments, when compressive force is applied to the inlet and outlet engagement members 220 and 240 , compressive force is also applied to the adapter 260 , enabling the adapter 260 to suspend the cartridge 250 within the inlet and outlet bodies 206 and 232 .

[0345] In some embodiments, when a compressive force is applied to the inlet coupling member 220 and the outlet coupling member 240, the inlet coupling flange 454 engages the adapter wall second portion 674 to form a first seal between the inlet coupling flange 454 and the adapter wall second portion 674.

The first gasket 246 is disposed between the inlet engaging member wall 650 and the adapter wall second portion 674, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet engaging member wall 650 and the adapter wall second portion 674. For example, the first gasket 246 engages the inlet engaging member wall 650 and the adapter wall second portion 674 to form a first seal therebetween. In this manner, when a compressive force is applied to the inlet engaging member wall 650, the first gasket 246 is compressed between the inlet engaging member wall 650 and the adapter wall second portion 674.

[0347] Similarly, aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet engagement member wall 660 and adapter wall fourth portion 678, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet engagement member wall 660 and adapter wall fourth portion 678. For example, second gasket 248 engages outlet engagement member wall 660 and adapter wall fourth portion 678 to form a second seal therebetween. In this manner, when a compressive force is applied to outlet engagement member wall 660, second gasket 248 is compressed between outlet engagement member wall 660 and adapter wall fourth portion 678.

[0348] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 30240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet joint member wall 650 engaging the adapter wall second portion 674. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet joint member wall 660 engaging the adapter wall fourth portion 678. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0349] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

The inclined plane is angled relative to the direction of extension of the outlet body 232. In some embodiments, the inclined plane is between 15° and 90° relative to the direction of extension of the outlet body 232. In some embodiments, the outlet joint member wall third portion 716 is curved so that the outlet joint member wall third portion 716 defines a curved wall portion between the outlet joint member wall second portion 714 and the upstream portion of the inlet joint member wall third portion 716, wherein the upstream portion of the outlet joint member wall third portion 716 extends along the inclined plane. The outlet joint member wall third portion 716 is adjacent to the outlet joint member wall second portion 714.

[0358] like Figure 31 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0359] The adapter 260 includes a base 720 that extends outward from the barrel wall 254. In some embodiments, the base 720 is attached to the outer surface of the barrel wall 254. In some embodiments, the base 720 is integrally formed with the barrel wall 254. In some embodiments, the base 720 is substantially parallel to the barrel wall 254 or coaxial with the barrel wall 254.

[0360] Adapter 260 also includes a protrusion 722 extending radially outward from base 720. In some embodiments, protrusion 722 is substantially perpendicular to base 720. In some embodiments, protrusion 722 is disposed between inlet coupling flange 706 and outlet coupling flange 716. Protrusion 722 includes a first engagement surface 724 (e.g., an upstream surface).

The first gasket 246 is disposed between the inlet coupling flange 706 and the first engaging surface 724, such that the first gasket 246 is separated from the cartridge wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling flange 706 and the first engaging surface 724. For example, the first gasket 246 engages the inlet coupling flange 706 and the first engaging surface 724 to form a first seal therebetween. Thus, when a compressive force is applied to the inlet coupling flange 706, the first gasket 246 is compressed between the inlet coupling flange 706 and the first engaging surface 724.

[0363] Similarly, aftertreatment system 200 can include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet coupling flange 716 and second engagement surface 726, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet coupling flange 716 and second engagement surface 726. For example, second gasket 248 engages outlet coupling flange 716 and second engagement surface 726 to form a second seal therebetween. Thus, when a compressive force is applied to outlet coupling flange 716, second gasket 248 is compressed between outlet coupling flange 716 and second engagement surface 726.

[0364] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 31 240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 706 engaging the first joint surface 724. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 716 engaging the second joint surface 726. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0365] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0366] Figure 32 is a cross-sectional view of an aftertreatment system 200 according to another example embodiment. Figure 32 In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) from the inlet body wall portion 214 . The inlet engagement member 220 includes an inlet engagement member wall 750 .

[0367] The inlet engaging member wall 750 includes an inlet engaging member wall first portion 752 that extends outwardly from and substantially parallel to the inlet body wall 214.

More specifically, the inlet engaging member wall first curved portion 753 extends along a curved path between the inlet body wall 214 and the inlet engaging member wall first portion 752.

[0368] The inlet joining member wall 750 includes an inlet joining member wall second portion 754.

The inclined surface is angled relative to the direction in which the inlet joining member wall first portion 752 and / or the inlet body wall 214 extend. In some embodiments, the inclined surface is between 15° and 90° relative to the direction in which the inlet joining member wall first portion 752 and / or the inlet body wall 214 extend. In some embodiments, the inlet joining member wall second portion 754 is adjacent to the inlet joining member wall first portion 752. In other embodiments, and as Figure 32 As shown, the inlet-joining member wall 750 includes an inlet-joining member wall second curved portion 755. The inlet-joining member wall second curved portion 755 is adjacent to the inlet-joining member wall first portion 752 and adjacent to the inlet-joining member wall second portion 754. The inlet-joining member wall second curved portion 755 extends outward (e.g., radially outward, axially outward, etc.) from the inlet-joining member wall first portion 752. More specifically, the inlet-joining member wall second curved portion 755 extends along a curved path between the inlet-joining member wall first portion 752 and the inlet-joining member wall second portion 754.

[0369] The inlet joining member wall 750 includes an inlet joining member wall third portion, referred to herein as an inlet coupling flange 756. The inlet coupling flange 756 extends inwardly (e.g., radially inwardly) and in a downstream direction from the inlet joining member wall second portion 754. The inlet coupling flange 756 extends along an inclined surface that is angled relative to the inlet joining member wall second portion 754. The inclined surface is angled relative to the direction in which the inlet joining member wall second portion 754 extends. In some embodiments, the inclined surface is between 15° and 180°, or more specifically, between 90° and 180°, relative to the direction in which the inlet joining member wall second portion 754 extends. In some embodiments, the inlet coupling flange 756 is adjacent to the inlet joining member wall second portion 754. In other embodiments, and as Figure 32As shown, the inlet coupling flange 756 includes an inlet coupling member wall third curved portion 757. The inlet coupling member wall third curved portion 757 is adjacent to the inlet coupling member wall second portion 754 and to the inlet coupling flange 756. The inlet coupling member wall third curved portion 757 extends outward (e.g., radially outward, axially outward, etc.) from the inlet coupling member wall second portion 754. More specifically, the inlet coupling member wall third curved portion 757 extends along a curved path between the inlet coupling member wall second portion 754 and the inlet coupling flange 756.

[0370] The outlet engaging member 240 is upstream of the outlet body wall portion 236 and flares or extends outwardly (eg, radially outwardly, axially outwardly, etc.) from the outlet body wall portion 236 . The outlet engaging member 240 includes an outlet engaging member wall 760 .

[0371] The outlet coupling member wall 760 includes an outlet coupling member wall first portion, referred to herein as an outlet coupling flange 766. The outlet coupling flange 766 extends outward (e.g., radially outward) from the outlet body wall 236. The outlet coupling flange 766 extends along an inclined surface that is angled relative to the direction in which the outlet coupling member wall first portion 462 extends. In some embodiments, the inclined surface is between 15° and 90° relative to the direction in which the outlet body wall 236 extends. In some embodiments, the outlet coupling flange 766 is substantially parallel to the inlet coupling flange 756. In some embodiments, the outlet coupling flange 766 is adjacent to the outlet body wall 236. In other embodiments, and as Figure 32 As shown, the outlet coupling flange 766 includes an outlet engaging member wall curvature 768. The outlet engaging member wall curvature 768 abuts the outlet body wall 236 and abuts the outlet coupling flange 766. The outlet engaging member wall curvature 768 extends outward (e.g., radially outward, axially outward, etc.) from the outlet body wall 236. More specifically, the outlet engaging member wall curvature 768 extends along a curved path between the outlet body wall 236 and the outlet coupling flange 766.

[0372] like Figure 32 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0373] The adapter 260 includes a base 770 that extends outward from the barrel wall 254. In some embodiments, the base 770 is attached to the outer surface of the barrel wall 254. In some embodiments, the base 770 is integrally formed with the barrel wall 254. In some embodiments, the base 770 is substantially parallel to the barrel wall 254 or coaxial with the barrel wall 254.

[0374] The adapter 260 also includes a protrusion 772 extending radially outward from the base 770. In some embodiments, the protrusion 772 extends along an inclined surface that is angled relative to the direction in which the base 770 and / or the barrel wall 254 extend. In some embodiments, the angle of the inclined surface relative to the direction in which the base 770 and / or the barrel wall 254 extend is between 15° and 90°. In some embodiments, the protrusion 772 is substantially parallel to the inlet coupling flange 756 and / or parallel to the outlet coupling flange 766. In some embodiments, the protrusion 772 is disposed between the inlet coupling flange 756 and the outlet coupling flange 766. In some embodiments, the protrusion 772 is adjacent to the base 770. In other embodiments, and as Figure 32 As shown, the protrusion 772 includes an adapter bend 774. The adapter bend 774 is adjacent to the base 770 and adjacent to the protrusion 772. The adapter bend 774 extends outward (e.g., radially outward and axially outward, etc.) from the base 770. More specifically, the adapter bend 774 extends along a curved path between the base 770 and the protrusion 772. In some embodiments, the protrusion 772 includes a first engagement surface 776 (e.g., an upstream surface). The protrusion 772 also includes a second engagement surface 778 (e.g., a downstream surface).

[0375] In some embodiments, the first engagement surface 776 engages the inlet coupling flange 756. In some embodiments, the engagement of the first engagement surface 776 with the inlet coupling flange 756 forms a first seal between the first engagement surface 776 and the inlet coupling flange 756.

[0376] In some embodiments, second engagement side 778 engages outlet coupling flange 766. In some embodiments, the engagement of second engagement side 778 with outlet coupling flange 766 forms a second seal therebetween.

[0377] In some embodiments, Figure 32The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet coupling flange 756 and the first engaging surface 776, such that the first gasket 246 is separated from the barrel wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling flange 756 and the first engaging surface 776. For example, the first gasket 246 engages the inlet coupling flange 756 and the first engaging surface 776 to form a first seal therebetween. Thus, when a compressive force is applied to the inlet coupling flange 756, the first gasket 246 is compressed between the inlet coupling flange 756 and the first engaging surface 776.

[0378] Similarly, aftertreatment system 200 can include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet coupling flange 766 and second engaging side 778, such that second gasket 248 is separated from cartridge wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet coupling flange 766 and second engaging side 778. For example, second gasket 248 engages outlet coupling flange 766 and second engaging side 778 to form a second seal therebetween. Thus, when a compressive force is applied to outlet coupling flange 766, second gasket 248 is compressed between outlet coupling flange 766 and second engaging side 778.

[0379] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 32 240 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet joint member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet joint member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the inlet coupling flange 756 engaging the first joint surface 776. A second seal (e.g., a metal-to-metal seal) can be formed by the outlet coupling flange 766 engaging the second joint side 778. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet joint member 220, the outlet joint member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0380] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0381] Figure 33 is a cross-sectional view of an aftertreatment system 200 according to another example embodiment. Figure 33 In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) and in a downstream direction from the inlet body wall portion 214 . The inlet engagement member 220 includes an inlet engagement member wall 800 .

[0382] The inlet engaging member wall 800 extends outwardly from the inlet body wall 214. The inlet engaging member wall 800 includes an inlet engaging member wall first portion 802 that extends outwardly from and substantially parallel to the inlet body wall 214. In some embodiments, the inlet engaging member wall first portion 802 is adjacent to the inlet body wall 214. In other embodiments, and as Figure 32As shown, the inlet engaging member wall 800 includes an inlet engaging member wall first curved portion 803. The inlet engaging member wall first curved portion 803 is adjacent to the inlet body wall 214 and adjacent to the inlet engaging member wall first portion 802. The inlet engaging member wall first curved portion 803 extends outward (e.g., radially outward, axially outward, etc.) from the inlet body wall 214. More specifically, the inlet engaging member wall first curved portion 803 extends along a curved path between the inlet body wall 214 and the inlet engaging member wall first portion 802.

[0383] The inlet engaging member wall 800 includes an inlet engaging member wall second portion 804. At least a portion of the inlet engaging member wall second portion 804 extends from the inlet engaging member wall first portion 802 along an inclined surface. The inclined surface is angled relative to the direction in which the inlet engaging member wall first portion 802 extends. The angle is between 15° and 90° relative to the direction in which the inlet engaging member wall first portion 802 extends. The inlet engaging member wall second portion 804 is adjacent to the inlet engaging member wall first portion 802.

[0384] The inlet engaging member wall second portion 804 includes an inlet engaging member wall first surface 805 (e.g., an outer surface) extending along an inclined surface. The inlet engaging member wall second portion 804 also includes an inlet engaging member wall second surface 806 (e.g., a radial surface, an inner surface, etc.) extending in a radial direction and substantially perpendicular to the direction of extension of the inlet engaging member wall first portion 802. The inlet engaging member wall second surface 806 is disposed opposite the inlet engaging member wall first surface 805 and toward the adapter 260. The inlet engaging member wall second portion 804 also includes an inlet engaging member wall third surface 807 (e.g., an inner surface) extending between the inlet engaging member wall first portion 802 and the inlet engaging member wall second surface 806. More specifically, the inlet engaging member wall third surface 807 is a curved surface extending along a curved path between the inlet engaging member wall first portion 802 and the inlet engaging member wall second surface 806.

[0385] The inlet coupling member 220 also includes an inlet coupling flange 808 that extends outward (e.g., axially outward) in a downstream direction from the inlet coupling member wall 800. The inlet coupling flange 808 extends outward (e.g., axially outward) in a downstream direction from the inlet body wall 214. More specifically, the inlet coupling flange 808 extends in a downstream direction away from the inlet coupling member wall second surface 806. The inlet coupling flange 808 abuts the inlet coupling member wall 800.

[0386] The outlet body 232 includes an outlet engaging member 240 positioned upstream of the outlet body wall 236 and flaring or extending outward (eg, radially outward, axially outward, etc.) and in an upstream direction from the outlet body wall 236 . The outlet engaging member 240 includes an outlet engaging member wall 810 .

[0387] The outlet engaging member wall 810 extends outwardly from the outlet body wall 236. The outlet engaging member wall 810 includes an outlet engaging member wall first portion 812 that extends outwardly from and substantially parallel to the outlet body wall 236. In some embodiments, the outlet engaging member wall first portion 812 is adjacent to the outlet body wall 236. In other embodiments, and as Figure 32 As shown, the outlet engaging member wall 810 includes an outlet engaging member wall first curved portion 813. The outlet engaging member wall first curved portion 813 is adjacent to the outlet body wall 236 and adjacent to the outlet engaging member wall first portion 812. The outlet engaging member wall first curved portion 813 extends outward (e.g., radially outward and axially outward, etc.) from the outlet body wall 236. More specifically, the inlet engaging member wall first curved portion 803 extends along a curved path between the outlet body wall 236 and the outlet engaging member wall first portion 812.

[0388] The outlet engaging member wall 810 includes an outlet engaging member wall second portion 814. At least a portion of the outlet engaging member wall second portion 814 extends from the outlet engaging member wall first portion 812 along an inclined surface. The inclined surface is angled relative to the direction of extension of the outlet engaging member wall first portion 812. The angle relative to the direction of extension of the outlet engaging member wall first portion 812 is between 15° and 90°. The outlet engaging member wall second portion 814 is adjacent to the outlet engaging member wall first portion 812.

[0389] The outlet engaging member wall second portion 814 includes an outlet engaging member wall first surface 815 (e.g., an outer surface) extending along an inclined surface. The outlet engaging member wall second portion 814 also includes an outlet engaging member wall second surface 816 (e.g., a radial surface, an inner surface) extending in a radial direction and substantially perpendicular to the direction of extension of the outlet engaging member wall first portion 812. The outlet engaging member wall second surface 816 is disposed opposite the outlet engaging member wall first surface 815 and toward the adapter 260. The outlet engaging member wall second portion 814 also includes an outlet engaging member wall third surface 817 (e.g., an inner surface) extending between the outlet engaging member wall first portion 812 and the outlet engaging member wall second surface 816. More specifically, the outlet engaging member wall third surface 817 is a curved surface extending along a curved path between the outlet engaging member wall first portion 812 and the outlet engaging member wall second surface 816.

[0390] The outlet coupling member 240 further includes an outlet coupling flange 818 extending outwardly (e.g., axially outwardly) in an upstream direction from the outlet coupling member wall 810. The outlet coupling flange 818 extends outwardly (e.g., axially outwardly) in an upstream direction from the outlet body wall 236. More specifically, the outlet coupling flange 818 extends in an upstream direction away from the outlet coupling member wall second surface 816. The outlet coupling flange 818 abuts the outlet coupling member wall 810.

[0391] like Figure 32 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0392] The adapter 260 includes a base 820 that extends outward from the barrel wall 254. In some embodiments, the base 820 is attached to the outer surface of the barrel wall 254. In some embodiments, the base 820 is integrally formed with the barrel wall 254. In some embodiments, the base 820 is substantially parallel to the barrel wall 254 or coaxial with the barrel wall 254.

[0393] Adapter 260 also includes a protrusion 822 extending outward (e.g., radially outward) from base 820. In some embodiments, protrusion 822 is substantially perpendicular to base 820. In some embodiments, protrusion 822 is disposed between inlet coupling flange 808 and outlet coupling flange 818. Protrusion 822 defines a first recess 823 (e.g., an upstream recess) having a first engagement surface 824 (e.g., an upstream engagement surface). Protrusion 562 also includes a second recess 825 (e.g., a downstream recess) having a second engagement surface 826 (e.g., a downstream engagement surface).

[0394] First recess 823 is sized to receive at least a portion of inlet coupling flange 808 such that the portion of inlet coupling flange 808 engages protrusion 822 at a first engagement surface 824. In some embodiments, the engagement of the portion of inlet coupling flange 808 and protrusion 822 at first engagement surface 824 forms a first seal between the portion of inlet coupling flange 808 and protrusion 822.

[0395] In some embodiments, the inlet coupling flange 808 engages the first engaging surface 824 and forms a seal between the inlet coupling flange 808 and the first engaging surface 824. In other embodiments, Figure 33 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet coupling flange 808 and the first engaging surface 824 (e.g., within the recess 823), such that the first gasket 246 is separated from the barrel wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling flange 808 and the first engaging surface 824. For example, the first gasket 246 engages the inlet coupling flange 808 and the first engaging surface 824 to form a first seal therebetween. Thus, when a compressive force is applied to the inlet coupling flange 808, the first gasket 246 is compressed between the inlet coupling flange 808 and the first engaging surface 824.

[0396] Second recess 825 is sized to receive at least a portion of outlet coupling flange 818 such that the portion of outlet coupling flange 818 engages protrusion 822 at second engagement surface 826. In some embodiments, the engagement of the portion of outlet coupling flange 818 and protrusion 562 at second engagement surface 826 forms a second seal between the portion of outlet coupling flange 818 and protrusion 562.

[0397] In some embodiments, the outlet coupling flange 818 engages at least a portion of the second engaging surface 826 and forms a seal therebetween. In other embodiments, the aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. The second gasket 248 is disposed between the outlet coupling flange 818 and the second engaging surface 826 (e.g., within the recess 825), such that the second gasket 248 is separated from the barrel wall 254 by the adapter 260. The second gasket 248 establishes a second seal between the outlet coupling flange 818 and the second engaging surface 826. For example, the second gasket 248 engages the outlet coupling flange 818 and the second engaging surface 826 to form a second seal therebetween. Thus, when a compressive force is applied to the outlet coupling flange 818, the second gasket 248 is compressed between the outlet coupling flange 818 and the second engaging surface 826.

[0398] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 33 80 and the adapter 260. In these embodiments, the first gasket 246 can be positioned between the inlet coupling member 220 and the adapter 260, and / or the second gasket 248 can be positioned between the outlet coupling member 240 and the adapter 260. In other embodiments, the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248. In these embodiments, a first seal (e.g., a metal-to-metal seal) can be formed by the engagement of a portion of the inlet coupling flange 808 and the protrusion 822 at the first engagement surface 824. A second seal (e.g., a metal-to-metal seal) can be formed by the engagement of a portion of the outlet coupling flange 818 and the protrusion 562 at the second engagement surface 826. Advantageously, when the aftertreatment system 200 does not include the first gasket 246 and / or the second gasket 248, the number of components in the connection created by the inlet coupling member 220, the outlet coupling member 240, and the adapter 260 is reduced, thereby simplifying the manufacturing process, the assembly process, and the replacement process. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0399] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0400] Figure 34 is a cross-sectional view of an aftertreatment system 200 according to another example embodiment. Figure 34 In the illustrated embodiment, the inlet engagement member 220 is downstream of the inlet body wall portion 214 and flares or extends outward (eg, radially outward, axially outward, etc.) from the inlet body wall portion 214 . The inlet engagement member 220 includes an inlet engagement member wall 830 .

[0401] The inlet engaging member wall 830 includes an inlet engaging member wall first portion 832 that extends outward (e.g., radially outward, axially outward) from the inlet body wall 214 in a downstream direction. More specifically, the inlet engaging member wall first portion 832 extends outward from the inlet body wall 214 along a curved path. In some embodiments, the inlet engaging member wall first portion 832 is adjacent to the inlet body wall 214. In other embodiments, and as Figure 34As shown, the inlet engaging member wall 830 includes an inlet engaging member wall first curved portion 833. The inlet engaging member wall first curved portion 833 is adjacent to the inlet body wall 214 and adjacent to the inlet engaging member wall first portion 832. The inlet engaging member wall first curved portion 833 extends outward (e.g., radially outward, axially outward, etc.) from the inlet body wall 214. More specifically, the inlet engaging member wall first curved portion 833 extends along a curved path between the inlet body wall 214 and the inlet engaging member wall first portion 832.

[0402] The inlet engaging member wall first portion 832 has an outer surface 834 (eg, an upstream surface) extending along a curved path. The inlet engaging member wall first portion 832 also includes an inner surface 835 disposed opposite the outer surface 834.

[0403] The inlet coupling member wall 830 includes an inlet coupling member wall second portion 836 (also referred to herein as an inlet coupling flange 836) that extends outward (e.g., radially outward, axially outward) in a downstream direction from the inlet body wall 214. More specifically, the inlet coupling flange 836 extends outward in a downstream direction from the inlet coupling member wall first portion 832. The inlet coupling flange 836 extends along a curved path. In some embodiments, the inlet coupling flange 836 abuts the inlet coupling member wall first portion 832.

[0404] The outlet engaging member 240 is upstream of the outlet body wall portion 236 and flares or extends outwardly (eg, radially outwardly, axially outwardly, etc.) from the outlet body wall portion 236 . The outlet engaging member 240 includes an outlet engaging member wall 840 .

[0405] The outlet engaging member wall 840 includes an outlet engaging member wall first portion 842 that extends outward (e.g., radially outward, axially outward) from the outlet body wall 236 in an upstream direction. More specifically, the outlet engaging member wall first portion 842 extends outward from the outlet body wall 236 along a curved path. In some embodiments, the outlet engaging member wall first portion 842 is adjacent to the outlet body wall 236. In other embodiments, and as Figure 34 As shown, the outlet engaging member wall 840 includes an outlet engaging member wall first curved portion 843. The outlet engaging member wall first curved portion 843 is adjacent to the outlet body wall 236 and adjacent to the outlet engaging member wall first portion 842. The outlet engaging member wall first curved portion 843 extends outward (e.g., radially outward and axially outward, etc.) from the outlet body wall 236. More specifically, the outlet engaging member wall first curved portion 843 extends along a curved path between the outlet body wall 236 and the outlet engaging member wall first portion 842.

[0406] The outlet engaging member wall first portion 842 has an outer surface 844 (eg, an upstream surface) extending along a curved path. The outlet engaging member wall first portion 842 also includes an inner surface 845 disposed opposite the outer surface 844.

[0407] The outlet coupling member wall 840 includes an outlet coupling member wall second portion 846 (also referred to herein as an outlet coupling flange 846) that extends outwardly (e.g., radially outwardly, axially outwardly) in an upstream direction from the outlet body wall 236. More specifically, the outlet coupling flange 846 extends outwardly in an upstream direction from the outlet coupling member wall first portion 842. The outlet coupling flange 846 extends along a curved path. In some embodiments, the outlet coupling flange 846 abuts the outlet coupling member wall first portion 842.

[0408] like Figure 32 As shown, the adapter 260 is disposed between the inlet engagement member 220 and the outlet engagement member 240. In some embodiments, the adapter 260 is coupled to the cartridge wall 254. In other embodiments, the adapter 260 is integrally formed with the cartridge wall 254. As described herein, the adapter 260 cooperates with the cartridge wall 254, the inlet engagement member 220, and the outlet engagement member 240 to facilitate suspending the cartridge 250 within the inlet body 206 and / or the outlet body 232 when a compressive force is applied to the adapter 260.

[0409] The adapter 260 includes a base 850 that extends outward from the barrel wall 254. In some embodiments, the base 850 is attached to the outer surface of the barrel wall 254. In some embodiments, the base 850 is integrally formed with the barrel wall 254. In some embodiments, the base 850 is substantially parallel to the barrel wall 254 or coaxial with the barrel wall 254.

[0410] Adapter 260 also includes a protrusion 852 extending radially outward from base 850. In some embodiments, protrusion 852 is substantially perpendicular to base 850. In some embodiments, protrusion 852 is disposed between inlet coupling flange 836 and outlet coupling flange 846. Protrusion 852 defines a first recess 853 (e.g., an upstream recess) having a first engagement surface 854. Protrusion 852 also includes a second recess 855 (e.g., a downstream recess) having a second engagement surface 856.

[0411] Inlet engaging member wall first portion 832 is received by first recess 853 such that inlet engaging member wall first portion 832 is at least partially disposed radially outward from at least a portion of protrusion 852. Inlet coupling flange 836 is at least partially disposed above adapter 260.

[0412] Outlet engaging member wall first portion 842 is received by second recess 855 such that outlet engaging member wall first portion 842 is at least partially disposed radially outward from at least a portion of protrusion 852. Outlet coupling flange 846 is at least partially disposed above adapter 260.

[0413] In some embodiments, the shape of the inlet engaging member wall 830 conforms to the shape of the upstream side of the protrusion 852. More specifically, the first recess 853 is sized to receive at least a portion of the inlet engaging member wall 830 such that the portion of the inlet engaging member wall 830, such as the inlet engaging member wall first portion 832, engages the protrusion 852 at a first engagement surface 854. In some embodiments, the engagement of the portion of the inlet engaging member wall 830 with the protrusion 852 at the first engagement surface 854 forms a first seal between the portion of the inlet engaging member wall 830 and the protrusion 852.

[0414] In some embodiments, inlet coupling flange 836 engages at least a portion of the upstream side of protrusion 852 and forms a seal between inlet coupling flange 836 and the upstream side of protrusion 852. In other embodiments, Figure 32 The illustrated aftertreatment system 200 includes a first gasket 246, also referred to herein as a first sealing member. The first gasket 246 is disposed between the inlet coupling flange 836 and the upstream side of the protrusion 852, such that the first gasket 246 is separated from the barrel wall 254 by the adapter 260. The first gasket 246 establishes a first seal between the inlet coupling flange 836 and the upstream side of the protrusion 852. For example, the first gasket 246 engages the inlet coupling flange 836 and the upstream side of the protrusion 852 to form a first seal between the inlet coupling flange 836 and the upstream side of the protrusion 852. Thus, when a compressive force is applied to the inlet coupling flange 836, the first gasket 246 is compressed between the inlet coupling flange 836 and the upstream side of the protrusion 852.

[0415] In some embodiments, the shape of the outlet engaging member wall 840 conforms to the shape of the downstream side of the protrusion 852. More specifically, the second recess 855 is sized to receive at least a portion of the outlet engaging member wall 840 such that the portion of the outlet engaging member wall 840 (such as the outlet engaging member wall first portion 842) engages the protrusion 852 at the second engaging surface 856. In some embodiments, the engagement of the portion of the outlet engaging member wall 840 with the protrusion 852 at the second engaging surface 856 forms a second seal between the portion of the outlet engaging member wall 840 and the protrusion 852.

[0416] In some embodiments, outlet coupling flange 846 engages at least a portion of the downstream side of protrusion 852 and forms a seal between outlet coupling flange 846 and the downstream side of protrusion 852. In other embodiments, aftertreatment system 200 may include a second gasket 248, also referred to herein as a second sealing member. Second gasket 248 is disposed between outlet coupling flange 846 and the downstream side of protrusion 852, such that second gasket 248 is separated from barrel wall 254 by adapter 260. Second gasket 248 establishes a second seal between outlet coupling flange 846 and the downstream side of protrusion 852. For example, second gasket 248 engages outlet coupling flange 846 and the downstream side of protrusion 852 to form a second seal between outlet coupling flange 846 and the downstream side of protrusion 852. Thus, when a compressive force is applied to outlet coupling flange 846, second gasket 248 is compressed between outlet coupling flange 846 and the downstream side of protrusion 852.

[0417] In other embodiments, the first gasket 246 and / or the second gasket 248 are disposed in a manner similar to that of FIG. Figure 34 852 . In various embodiments, the aftertreatment system 200 may include the first gasket 246 and / or the second gasket 248 ... In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 also mitigates gasket creep.

[0418] In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 does not form a seal between the inlet engaging member 220 and the adapter 260, and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 does not form a seal between the outlet engaging member 240 and the adapter 260. In some embodiments, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 provides an alternative path for external forces to pass through the connection created by the inlet engaging member 220, the outlet engaging member 240, and the adapter 260. Advantageously, the metal-to-metal contact between the inlet engaging member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engaging member 240 and the adapter 260 prevents excessive compression of gaskets (e.g., the first gasket 246 and / or the second gasket 248) due to external forces. In some embodiments, the metal-to-metal contact between the inlet engagement member 220 and the adapter 260 and / or the metal-to-metal contact between the outlet engagement member 240 and the adapter 260 can also control gasket compression through the fit between the metal components and the gasket. For example, the cross-sectional space created by the fit of the metal components (e.g., the inlet engagement member 220, the outlet engagement member 240, and the adapter 260) is slightly smaller than the cross-sectional area of ​​the gasket (e.g., the first gasket 246 and / or the second gasket 248), thereby controlling the amount of gasket compression.

[0419] In any of the embodiments described herein, arrangements for gasket or sealing member (e.g., first gasket 246, second gasket 248, etc.) compression utilizing a metal-to-metal load path and / or metal tolerance control benefit from improved uniformity of gasket compression around the perimeter of the sealing surface (e.g., the surface that engages or contacts the gasket or sealing member). The through-metal load path ensures that one half of the gasket is not over-compressed while the other half is not under-compressed. When the gasket is properly compressed, leakage can be more effectively reduced. Furthermore, in arrangements for gasket compression utilizing a metal-to-metal load path and / or metal tolerance control, assembly offset variation is reduced, thereby reducing assembly tolerances over the length of the aftertreatment system 200.

[0420] Furthermore, the metal-to-metal contact allows for tighter compressive loads from fasteners such as clamp 170 without damaging the gasket and higher rigidity at the connection. Furthermore, the physical limitations governing gasket compression as seen in the metal-to-metal arrangement prevent excessive loads on the gasket, which could lead to gasket creep and gasket failure over the gasket's useful life.
