[0002] This disclosure generally relates to exhaust aftertreatment systems, aftertreatment component cartridges, and installation methods for internal combustion engines.

[0003] background For internal combustion engine systems, it may be necessary to replace or reuse components of the aftertreatment system used to capture harmful substances and particulates in the exhaust gases produced by fuel combustion. Therefore, such components in the aftertreatment system can be designed to be removable.

[0004] One approach that can be implemented in an aftertreatment system is to use wire mesh ropes to support aftertreatment system components used to capture unwanted substances and particles. However, existing designs with wire mesh ropes may allow some unwanted substances and particles to pass through the wire mesh ropes, which reduces the efficiency of the internal combustion engine system.

[0005] Other methods involve assembling the aftertreatment system using multiple joints or clamps at either end of the component. However, these methods increase the amount of space required for the aftertreatment system, leading to increased costs and reduced space for other systems. Furthermore, because these methods utilize multiple joints, the possibility of exhaust gases escaping through these joints and causing temperatures to rise in surrounding components increases.

[0006] Overview In one embodiment, the post-treatment system includes an inlet conduit assembly, an outlet conduit assembly, and a post-treatment component cylinder. The inlet conduit assembly includes an inlet body comprising an inlet body wall portion and an inlet connection flange portion flaring outward from the inlet body wall portion. The outlet conduit assembly is located downstream of the inlet conduit assembly and includes an outlet body comprising an outlet body wall portion and an outlet connection flange portion flaring outward from the outlet body wall portion. The post-treatment component cylinder includes a post-treatment component housing and an adapter. The adapter includes: a first flange portion coupled to the post-treatment component housing and disposed between the inlet body wall portion and the post-treatment component housing; a second flange portion coupled to the post-treatment component housing and disposed between the outlet body wall portion and the post-treatment component housing; and an adapter body contacting the inlet connection flange portion and the outlet connection flange portion. The adapter body includes a first base surface, a crown surface, a first recess between the first base surface and the crown surface, and a first gasket including a portion disposed within the first recess.

[0007] Another embodiment includes a method for mounting a post-treatment component cylinder in a post-treatment system having an inlet conduit assembly, an outlet conduit assembly, and a clamp. The inlet conduit assembly includes an inlet body having an inlet body wall portion and an inlet connection flange portion. The outlet conduit assembly includes an outlet body having an outlet body wall portion and an outlet connection flange portion. The post-treatment component cylinder includes a post-treatment component housing and an adapter having a first flange portion connected to the post-treatment component housing and a second flange portion connected to the post-treatment component housing. The clamp includes a first clamp flange portion and a second clamp flange portion. The method for mounting the post-treatment component cylinder in the post-treatment system includes the steps of: inserting the post-treatment component housing into the inlet body and the outlet body such that the first flange portion is disposed between the post-treatment component housing and the inlet body wall portion, and the second flange portion is disposed between the post-treatment component housing and the outlet body wall portion. The method further includes aligning the adapter with the inlet connection flange portion and the outlet connection flange portion face-to-face. The method further includes compressing a first gasket in a first recess between the adapter and the inlet connection flange portion such that the adapter contacts the inlet connection flange portion. The method also includes compressing the second gasket in the second recess between the adapter and the outlet connection flange portion, such that the adapter contacts the outlet connection flange portion.

[0008] Another embodiment includes a post-treatment system comprising an inlet conduit assembly, an outlet conduit assembly, and a post-treatment component cylinder. The inlet conduit assembly includes an inlet body comprising an inlet body wall portion and an inlet connection flange portion flaring outward from the inlet body wall portion. The outlet conduit assembly is located downstream of the inlet conduit assembly and includes an outlet body comprising an outlet body wall portion and an outlet connection flange portion flaring outward from the outlet body wall portion.

[0011] Detailed description The following is a more detailed description of various concepts and embodiments related to methods and apparatus for providing post-processing component cylinders for post-processing systems. The various concepts introduced above and discussed in more detail below can be implemented in any of a variety of ways, as the described concepts are not limited to any particular implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

[0012] I. Overview To reduce emissions, it may be desirable to use aftertreatment system components to treat exhaust gases. After a certain amount of exhaust gas has been treated by the aftertreatment system components, they may need to be repaired or replaced. Furthermore, it may sometimes be necessary to remove the aftertreatment component housing and replace it with a different aftertreatment system component, thus reusing the aftertreatment system from one application to another. In many aftertreatment systems, removing, repairing, and replacing aftertreatment system components can be difficult or impossible because the components are non-removable and / or not easily accessible to the user. One way to repair and replace aftertreatment system components is to secure them to the aftertreatment system using multiple clamps. However, the use of multiple clamps increases the overall cost and space required for the aftertreatment system, limiting the space available for other systems. The use of multiple clamps also reduces the area available for isolation on the exterior of the aftertreatment system. Additionally, the use of multiple clamps increases the number of connections and openings for exhaust gas escaping, which may increase the temperature of the exterior and surrounding components of the aftertreatment system.

[0013] Aftertreatment systems are constrained by space requirements, which are the amount of physical space consumed by the aftertreatment system during installation (e.g., on a vehicle) and the location of that physical space (e.g., coordinates relative to the vehicle's coordinate system). In some applications, the physical space available to the aftertreatment system is limited due to the location of surrounding components, wiring or piping requirements, or other similar constraints. Therefore, it is often difficult to modify the aftertreatment system, as such modifications typically increase its space requirements. Such modifications may necessitate the use of various components within the aftertreatment system, such as different types of filters or catalytic converters.

[0014] The embodiments described herein relate to an aftertreatment system having an inlet conduit assembly, an outlet conduit assembly, and at least one aftertreatment component cylinder containing aftertreatment system components. The inlet conduit assembly includes an inlet connection flange portion, and the outlet conduit assembly includes an outlet connection flange portion. The aftertreatment component cylinder includes an adapter that cooperates with the inlet and outlet connection flanges and facilitates the suspension of the aftertreatment system components within the housing by securing the aftertreatment component cylinder to the inlet and outlet bodies using fasteners (e.g., clamps, bolted connections, V-belt body connections, etc.). Thus, an internal combustion engine utilizing the aftertreatment system described herein is more desirable than other aftertreatment systems with multiple clamps that 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 connection flanges and the adapter to be held by fasteners in this arrangement, the space requirements of the aftertreatment system described herein can be significantly less than other systems that do not utilize such an arrangement. Furthermore, by using fasteners in such an arrangement, the area for isolation on the outside of the aftertreatment system is increased, and the number of connections and openings from which exhaust gas may escape is reduced.

[0015] II. Overview of Example Post-Processing Systems Figures 1 to 5 as well as Figure 8 An aftertreatment system 100 (e.g., a treatment system, etc.) for treating exhaust gases produced by internal combustion engines (e.g., diesel internal combustion engines, gasoline internal combustion engines, hybrid internal combustion engines, propane internal combustion engines, dual-fuel internal combustion engines, etc.) is described. As explained in more detail herein, the aftertreatment system 100 is easier and faster to maintain than other systems (e.g., by changing the type of one or more aftertreatment components, etc.), thus making the aftertreatment system 100 more ideal than other systems.

[0016] The aftertreatment system 100 includes an inlet duct assembly 102 (e.g., a pipeline system, piping system, etc.). The inlet duct assembly 102 includes an inlet exhaust duct 104 (e.g., a piping system, etc.) that receives exhaust gases from an upstream component (e.g., a manifold on an internal combustion engine, an exhaust manifold on an internal combustion engine, an internal combustion engine, etc.). In some embodiments, the inlet exhaust duct 104 is coupled (e.g., attached, fixed, welded, fastened, riveted, adhesively attached, joined, pinned, etc.) to the upstream component. In other embodiments, the inlet exhaust duct 104 is integrally formed with the upstream component.

[0017] The inlet duct assembly 102 also includes an inlet body 106 (e.g., a body, panel, etc.). The inlet duct assembly 102 also includes an inlet housing 108 (e.g., a housing, 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., annular protrusion, circular bulge, annular rib, etc.) to connect the inlet housing 108 to the inlet body 106. The inlet housing 108 also includes a second inlet housing flange 112 (e.g., annular protrusion, circular bulge, annular rib, etc.) to connect the inlet housing 108 to the inlet body 106. The inlet body 106 includes an inlet body wall portion 114 (e.g., a body, panel, etc.). The inlet body wall portion 114 receives exhaust gas flow from the inlet exhaust duct 104.

[0018] In some embodiments, the inlet exhaust duct 104 includes an inlet exhaust duct flange (e.g., annular protrusion, circular bulge, annular rib, etc.) which is disposed between and connected to the inlet body wall portion 114 and the first inlet housing flange 110. The inlet exhaust duct flange facilitates the connection of the inlet exhaust duct 104 to the inlet conduit assembly 102.

[0019] In some embodiments, the inlet duct assembly 102 further includes an inlet isolator (e.g., an isolator, a pad, etc.). The inlet isolator is disposed between the inlet body wall portion 114 and the inlet housing 108. When exhaust gas enters the inlet duct assembly 102, the inlet isolator serves to mitigate the temperature rise of the inlet housing 108. The inlet isolator may be, for example, an isolator pad, a ceramic fiber pad, or other similar components.

[0020] The inlet body 106 also includes an inlet connection flange portion 120 (e.g., annular protrusion, circular bulge, annular rib, etc.). The inlet connection flange portion 120 is downstream of the inlet body wall portion 114 and flares outward from the inlet body wall portion 114 (e.g., radially outward and axially outward). More specifically, the inlet connection flange portion 120 extends from the inlet body wall portion 114 along a ramp. The ramp is at an angle to a reference plane bisecting the inlet body 106. In some embodiments, the inlet connection flange portion 120 may include a bent end.

[0021] In some embodiments, the inlet body 106 further includes an inlet curved portion 122, such as Figure 3 , Figure 5 and Figure 8As shown in the diagram, the inlet bend 122 abuts against the inlet body wall portion 114 and the inlet connecting flange portion 120. Similar to the inlet connecting flange portion 120, the inlet bend 122 flares outward. More specifically, the inlet bend 122 extends along a ramp from the inlet body wall portion 114, and the inlet connecting flange portion 120 extends along a ramp from the inlet bend 122. As a result, the inlet bend 122 creates a gap within the post-processing system 100 to accommodate another component.

[0022] The inclined plane forms an angle with the reference plane that bisects the inlet body 106. The angle of the inclined plane of the inlet connecting flange portion 120 is greater than the angle of the inclined plane of the inlet curved portion 122 (e.g., where in...). Figure 3 In this context, the angle is measured counterclockwise, etc. For example, the angle difference can be approximately between 10 and 30 degrees. This angle difference allows the inlet body 106 to have a shape that facilitates connection to other components of the post-processing system 100. In other embodiments, the inlet body 106 may include a straight inlet portion 212, such as... Figure 4 As shown. The inlet straight portion 212 is adjacent to the inlet body wall portion 114 and the inlet connecting flange portion 120. The inlet straight portion 212 may be parallel to the first flange portion 154. As a result, the inlet straight portion 212 creates a gap within the aftertreatment system 100 to accommodate another component.

[0023] Return to reference Figures 1 to 5 as well as Figure 8 As explained in more detail below, the aftertreatment system 100 also includes an outlet duct assembly 124 (e.g., a pipeline system, piping system, etc.). The outlet duct assembly 124 is configured to supply exhaust gas from the aftertreatment system 100 (e.g., to downstream components, to the atmosphere, etc.).

[0024] The outlet duct assembly 124 includes an outlet exhaust duct 126 (e.g., a pipeline system, piping system, etc.). The outlet exhaust duct 126 provides exhaust gas from the aftertreatment system 100. The outlet duct assembly 124 also includes an outlet body 128 (e.g., a body, panel, etc.). The outlet duct assembly 124 also includes an outlet housing 130 (e.g., a housing, 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, panel, etc.).

[0025] In some embodiments, the outlet conduit assembly 124 further includes an outlet isolator (e.g., an isolator, a pad, etc.). The outlet isolator is disposed between the outlet body wall portion 132 and the outlet housing 130. The outlet isolator 134 is used to mitigate the temperature rise of the outlet housing 130. The outlet isolator may be, for example, an isolator pad, a ceramic fiber pad, or other similar components.

[0026] The outlet body 128 also includes an outlet connection flange portion 136 (e.g., annular protrusion, circular bulge, annular rib, etc.). The outlet connection 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 connection flange portion 136 extends from the outlet body wall portion 132 along a ramp. The outlet connection flange portion 136 extends from the outlet body wall portion 132 along the ramp in a first direction, and the inlet connection flange portion 120 extends from the inlet body wall portion 114 along the ramp in a second direction opposite to the first direction. In some embodiments, the outlet connection flange portion 136 may include a bent end.

[0027] In some embodiments, the outlet body 128 further includes an outlet curved portion 138, such as Figure 3 , Figure 5 and Figure 8 As shown. The outlet bend 138 abuts the outlet body wall portion 132 and the outlet connecting flange portion 136. Similar to the outlet connecting flange portion 136, the outlet bend 138 flares outward. More specifically, the outlet bend 138 extends from the outlet body wall portion 132 along a ramp, and the outlet connecting flange portion 136 extends from the outlet bend 138 along a ramp. As a result, the outlet bend 138 creates a gap within the aftertreatment system 100 that can accommodate another component. The ramp is angled to the reference plane that bisects the outlet body 128. The angle of the ramp of the outlet connecting flange portion 136 is greater than the angle of the ramp of the inlet bend 138 (e.g., where in...). Figure 3 In this context, the angle is measured counterclockwise, etc. For example, the angle difference can be approximately between 10 and 30 degrees. This angle difference allows the outlet body 128 to have a shape that facilitates connection to other components of the post-processing system 100.

[0028] exist Figures 2 to 5 In this system, the post-treatment system 100 includes a post-treatment component cylinder 140 (e.g., a tube, insert, etc.). As explained in more detail herein, the inlet connection flange portion 120 and the outlet connection flange portion 136 mate to facilitate the suspension of the post-treatment component cylinder 140 within the inlet body 106 and the outlet body 128.

[0029] The aftertreatment component cylinder 140 includes an aftertreatment component housing 142 (e.g., a filter housing, etc.). The aftertreatment component housing 142 facilitates the flow of exhaust gas from the inlet duct assembly 102 into the aftertreatment component cylinder 140.

[0030] The aftertreatment component housing 142 includes an inlet portion. The inlet portion is inserted into an inlet duct assembly 102. The inlet portion receives exhaust gas from the inlet duct assembly 102 and supplies exhaust gas to the aftertreatment component cylinder 140. The aftertreatment component housing 142 also includes an outlet portion. The outlet portion is inserted into an outlet duct assembly 124. The outlet portion receives exhaust gas from the aftertreatment component cylinder 140 and supplies exhaust gas from the aftertreatment component cylinder 140.

[0031] like Figure 2 As shown, the aftertreatment component housing 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 gases produced by an internal combustion engine. In some embodiments, the aftertreatment system component 148 reduces emissions of unwanted components (e.g., nitrogen oxides (NOx)). In some embodiments, the aftertreatment system component 148 facilitates the removal of particles (e.g., soot, particulate matter, etc.) from the exhaust gases via a filter element (e.g., a diesel particulate filter (DPF)). In other embodiments, the aftertreatment system component 148 is a conversion catalyst element (e.g., a selective catalytic reduction (SCR) conversion catalyst element, a catalyst metal, etc.) that facilitates the conversion of various oxidizing components of the exhaust gases (e.g., carbon monoxide (CO), hydrocarbons, etc.) into other components (e.g., carbon dioxide (CO2), water vapor, etc.).

[0032] The post-treatment component cylinder 140 is not limited to housing a single post-treatment system component 148. Rather, the post-treatment component cylinder 140 may contain more than one post-treatment system component 148, each of which can be any of the embodiments described herein. In some embodiments, two post-treatment system components 148 are identical. For example, both post-treatment system components 148 can be conversion catalyst components. In another example, both post-treatment system components 148 can be filter components. In other embodiments, the post-treatment system components 148 are different from each other. For example, the upstream post-treatment system component 148 can be a filter component, while the downstream post-treatment system component 148 can be a conversion catalyst component.

[0033] In some embodiments, the post-processing component cylinder 140 further includes a mounting pad 150 (e.g., a compressible pad, etc.). The mounting pad 150 is disposed between the post-processing system component 148 and the post-processing component housing 142. The mounting pad 150 facilitates the connection between the post-processing system component 148 and the post-processing component housing 142.

[0034] refer to Figures 2 to 5 as well as Figure 8The post-processing component cylinder 140 includes an adapter 152 (e.g., a protrusion, ridge, rib, etc.). The adapter 152 is coupled to the post-processing component housing 142. The adapter 152 cooperates with the post-processing component housing 142, the inlet connection flange portion 120, and the outlet connection flange portion 136 to facilitate suspension of the post-processing component cylinder 140 within the inlet body 106 and the outlet body 128 when a compressive force is applied to the adapter 152.

[0035] In some embodiments, the adapter 152 includes a first flange portion 154 (e.g., a ring, etc.) coupled to the post-processing component housing 142 and a second flange portion 156 (e.g., a ring, etc.) coupled to the post-processing component housing 142. By coupling the first flange portion 154 to the post-processing component housing 142 and the second flange portion 156 to the post-processing component housing 142, when compressive force is applied to the adapter 152, the first flange portion 154 and the second flange portion 156 facilitate the suspension of the post-processing component cylinder 140 within the inlet body 106 and the outlet body 128. In some embodiments, such as Figure 3 and Figure 4 As shown, the first flange portion 154 and the second flange portion 156 are straight lines. In other embodiments, such as Figure 5 and Figure 8 As shown, the first flange portion 154 includes a first stop 214 defined with a certain curvature within the first flange portion 154. Similarly, the second flange portion 156 includes a second stop 216 defined with a certain curvature within the second flange portion 156.

[0036] When the first flange portion 154 is connected to the post-processing component housing 142, the first flange portion 154 is disposed between the inlet main body wall portion 114 and the post-processing component housing 142. Similarly, when the second flange portion 156 is connected to the post-processing component housing 142, the second flange portion 156 is disposed between the outlet main body wall portion 132 and the post-processing component housing 142. In some embodiments, the user may receive a post-processing component cylinder 140 in which the first flange portion 154 is connected to the post-processing component housing 142 and the second flange portion 156 is connected to the post-processing component housing 142.

[0037] In other embodiments, the first flange portion 154 and the second flange portion 156 are initially separate from the post-processing component housing 142. In these embodiments, a user can attach the first flange portion 154 to the post-processing component housing 142 and the second flange portion 156 to the post-processing component housing 142 during an installation process (e.g., a method, etc.) to install the post-processing component cylinder 140 of the post-processing system 100.

[0038] refer to Figures 3 to 5 as well as Figure 8Adapter 152 includes adapter body 184. In some embodiments, such as Figure 3 and Figure 4 As shown, the adapter body 184 includes a first base surface 186, a crown surface 161 (e.g., a curved protrusion, a circular bulge, etc.), a second base surface 200, a first recess 190 (e.g., a cavity, etc.), and a second recess 202 (e.g., a cavity, etc.). The first base surface 186 is disposed between and connects the first flange portion 154 and the first recess 190. The first base surface 186 extends from the first flange portion 154 along a ramp, such that a portion of the first base surface 186 can be parallel to the inlet connection flange portion 120. The ramp forms an angle with the reference plane of the adapter 152. The second base surface 200 is disposed between and connects the second flange portion 156 and the second recess 202. The second base surface 200 extends from the second flange portion 156 along a ramp, such that a portion of the second base surface 200 can be parallel to the outlet connection flange portion 136. The inclined plane forms an angle with the reference plane of the bisecting adapter 152. The adapter 152 is face-to-face with the inlet connection flange portion 120 and the outlet connection flange portion 136.

[0039] In some embodiments, such as Figure 5 and Figure 8 As shown, the adapter body 184 includes a crown surface 161 (e.g., a curved protrusion, a rounded bulge, etc.), a first base surface 186, and a second base surface 200. The first base surface 186 is disposed between and connects the first stop 214 and the crown surface 161. The first base surface 186 extends from one end of the first stop 214 along a ramp, such that a portion of the first base surface 186 can be parallel to the inlet curved portion 122. The ramp forms an angle with a reference plane that bisects the adapter 152. The second base surface 200 is disposed between and connects the second stop 216 and the crown surface 161. The second base surface 200 extends from one end of the first stop 216 along a ramp, such that a portion of the second base surface 200 can be parallel to the inlet curved portion 138. The ramp forms an angle with a reference plane that bisects the adapter 152. The adapter 152 is face-to-face with the inlet connection flange 120 and the outlet connection flange 136.

[0040] In some embodiments, such as Figure 3As shown, the adapter body 184 extends between and contacts the inlet connection flange portion 120 and the outlet connection flange portion 136. The adapter body 184 is solid between the first recess 190 and the second recess 202, and the adapter body 184 can be formed of metal (e.g., steel, aluminum, etc.). The metal can be formed by bending, stamping, casting, additive manufacturing, etc. A crown surface 161 is disposed between and connects the first recess 190 and the second recess 202, and has a semi-circular shape. The inlet connection flange portion 120 extends along a portion of the crown surface 161 and contacts a portion of the crown surface 161.

[0041] A portion of the inlet connection flange portion 120 of the crown surface 161 may abut against the first recess 190. An outlet connection flange portion 136 extends along and contacts a portion of the crown surface 161. A portion of the outlet connection flange portion 136 of the crown surface 161 may abut against the second recess 202. In this way, when compressive force is applied to the inlet connection flange portion 120 and the outlet connection flange portion 136, compressive force is also applied to the adapter 152, specifically to the crown surface 161. This allows the first flange portion 154 and the second flange portion 156 to suspend the post-processing component housing 142 within the inlet body 106 and the outlet body 128.

[0042] In such Figure 4 In some embodiments shown, the adapter body 184 is hollow between the inlet connection flange portion 120 and the outlet connection flange portion 136. The adapter body 184 may be formed of a metal of constant thickness. A crown surface 161 is disposed between and connects the first recess 190 and the second recess 202. The inlet connection flange portion 120 extends along a portion of the crown surface 161 and a portion of the first base surface 186 and contacts a portion of the crown surface 161 and the first base surface 186. The portion of the crown surface 161 that contacts the inlet connection flange portion 120 may abut against the first recess 190. The crown surface 161 has a portion that may be parallel to the inlet connection flange portion 120 to facilitate multi-point contact between the crown surface 161 and the inlet connection flange portion 120. The portion of the first base surface 186 that contacts the inlet connection flange portion 120 may abut against the first recess 190. The first base surface 186 has a portion that can be parallel to the inlet connection flange portion 120 to facilitate multi-point contact between the first base surface 186 and the inlet connection flange portion 120.

[0043] The outlet connection flange portion 136 extends along and contacts a portion of the crown surface 161 and the second base surface 200. The portion of the crown surface 161 that contacts the outlet connection flange portion 136 may abut against the second recess 202. The crown surface 161 has a portion that may be parallel to the outlet connection flange portion 136, thereby facilitating multi-point contact between the crown surface 161 and the outlet connection flange portion 136. The portion of the second base surface 200 that contacts the outlet connection flange portion 136 may abut against the second recess 202. The second base surface 200 has a portion that may be parallel to the outlet connection flange portion 136 to facilitate multi-point contact between the second base surface 200 and the outlet connection flange portion 136. In this way, when compressive force is applied to the inlet connection flange portion 120 and the outlet connection flange portion 136, the compressive force is also applied to the adapter 152, specifically to the crown surface 161, the first base surface 186, and the second base surface 200. This allows the first flange portion 154 and the second flange portion 156 to suspend the post-processing component housing 142 within the inlet body 106 and the outlet body 128.

[0044] In some embodiments, such as Figure 5 and Figure 8 As shown, the adapter body 184 is hollow between the inlet connection flange portion 120 and the outlet connection flange portion 136. The adapter body 184 may be formed of a metal of constant thickness. A crown surface 161 is disposed between and connects the first base surface 186 and the second base surface 200. The inlet connection flange portion 120 extends along a portion of the crown surface 161 and contacts a portion of the crown surface 161. The portion of the crown surface 161 that contacts the inlet connection flange portion 120 may abut against the first base surface 186. The crown surface 161 has a portion that may be parallel to the inlet connection flange portion 120 to facilitate multi-point contact between the crown surface 161 and the inlet connection flange portion 120.

[0045] The outlet connection flange portion 136 extends along and contacts a portion of the crown surface 161. A portion of the crown surface 161 that contacts the outlet connection flange portion 136 may abut against the second base surface 200. The crown surface 161 has portions that can be parallel to the outlet connection flange portion 136, thereby facilitating multi-point contact between the crown surface 161 and the outlet connection flange portion 136. In this way, when compressive forces are applied to the inlet connection flange portion 120 and the outlet connection flange portion 136, compressive forces are also applied to the adapter 152, specifically to the crown surface 161. This allows the first flange portion 154 and the second flange portion 156 to suspend the aftertreatment component housing 142 within the inlet body 106 and the outlet body 128.

[0046] refer to Figures 2 to 5 as well as Figure 8 In some embodiments, the post-processing system 100 includes a first gasket 166 (e.g., a gasket, seal, plug, etc.). The first gasket 166 in Figures 3 to 5 and Figure 8 The image shows the material in a compressed state. The first washer 166 may be made of a compressible material (e.g., rubber, elastomer, etc.). In some embodiments, such as... Figure 3 and Figure 4 As shown, a first gasket 166 is disposed and compressed between the inlet connection flange portion 120 and the adapter body 184, such that the first gasket 166 is separated from the post-processing component housing 142 via the adapter body 184. The first gasket 166 establishes a seal between the inlet connection flange portion 120 and the adapter body 184. A portion of the first gasket 166 may be disposed within a first recess 190. In some embodiments, the entire first gasket 166 may be disposed within the first recess 190. In this way, when compressive force is applied to the inlet connection flange portion 120, the first gasket 166 is compressed within the first recess 190 between the inlet connection flange portion 120 and the adapter body 184. In some embodiments, as Figure 8 As shown, the first washer 166 has an oval cross-section in the compressed state and a circular cross-section in the uncompressed state. In this way, tolerance deviations in the post-processing system 100 will have a smaller impact on the compression consistency of the first washer 166. In some embodiments, the first washer 166 has a circular cross-section in both the compressed and uncompressed states.

[0047] In other embodiments, such as Figure 5 and Figure 8 As shown, a first gasket 166 is disposed between the inlet bend 122 and the adapter body 184, such that the first gasket 166 is separated from the post-processing component housing 142 via the adapter body 184. The first gasket 166 establishes a seal between the inlet bend 122 and the adapter body 184. A portion of the first gasket 166 may be disposed on the first base surface 186 between the first stop 214 and the crown surface 161. The first stop 214 is configured to restrict movement of the first gasket 166 toward the first flange portion 154. Thus, when a compressive force is applied to the inlet connecting flange portion 120, the first gasket 166 is compressed between the inlet bend 122 and the adapter body 184. In some embodiments, the first base surface 186 may define a recess configured to receive the first gasket 166 having a circular cross-section (e.g., the first base surface 186 defines a bend configured to receive the first gasket 166 when it forms a circular cross-section in an uncompressed state, etc.).

[0048] In such Figure 3 In some embodiments shown, the first recess 190 includes a first wall 194, a second wall 196, and a third wall 198. The first wall 194 abuts against a first base surface 186 and may be parallel to the first flange portion 154. The second wall 196 abuts against the first wall 194 and connects the first wall 194 and the third wall 198. In some embodiments, the second wall 196 is parallel to a portion of the first base surface 186. The third wall 198 abuts against the crown surface 161 and may be parallel to the first flange portion 154. Figure 4 In other embodiments shown, the first recess 190 includes a first wall 194 and a second wall 196. The first wall 194 is adjacent to the first base surface 186 and may be parallel to the first flange portion 154. The second wall 196 is adjacent to the crown surface 161 and the second wall 196, and may be perpendicular to the first flange portion 154.

[0049] Similarly, the aftertreatment system 100 may include a second gasket 168 (e.g., a gasket, seal, plug, etc.). The second gasket 168 may be made of a compressible material (e.g., rubber, elastomer, etc.). The second gasket 168 in... Figures 3 to 5 as well as Figure 8 The image shows a compressed state. In some embodiments, such as... Figure 3 and 4 As shown, a second gasket 168 is disposed and compressed between the outlet connection flange portion 136 and the adapter body 184, such that the second gasket 168 is separated from the post-processing component housing 142 via the adapter body 184. The second gasket 168 establishes a seal between the outlet connection flange portion 136 and the connector portion 184. A portion of the second gasket 168 may be disposed within the second recess 202. In some embodiments, the entire second gasket 168 may be disposed within the second recess 202. In this way, when compressive force is applied to the outlet connection flange portion 136, the second gasket 168 is compressed within the second recess 202 between the outlet connection flange portion 136 and the adapter body 184. In some embodiments, as Figure 8 As shown, the second washer 168 has an oval cross-section in the compressed state and a circular cross-section in the uncompressed state. In this way, the tolerance deviations of the post-processing system 100 will have a smaller impact on the compression consistency of the second washer 168. In some embodiments, the second washer 168 has a circular cross-section in both the compressed and uncompressed states.

[0050] In other embodiments, such as Figure 5 and Figure 8As shown, a second gasket 168 is disposed and compressed between the outlet bend 138 and the adapter body 184, such that the second gasket 168 is separated from the post-processing component housing 142 via the adapter body 184. The second gasket 168 establishes a seal between the outlet bend 138 and the adapter body 184. A portion of the second gasket 168 may be disposed on the second base surface 200 between the second stop 216 and the crown surface 161. The second stop 216 is configured to restrict movement of the second gasket 168 toward the second flange portion 156. In this way, when a compressive force is applied to the outlet connection flange portion 136, the second gasket 168 is compressed between the outlet bend 136 and the adapter body 184. In some embodiments, the second base surface 200 may define a recess configured to receive the second gasket 168 having a circular cross-section (e.g., the second base surface 200 defines a bend configured to receive the second gasket 168 having a circular cross-section in an uncompressed state, etc.).

[0051] In such Figure 3 In some embodiments shown, the second recess 202 includes a fourth wall 206, a fifth wall 208, and a sixth wall 210. The fourth wall 206 abuts the second base surface 200 and may be parallel to the second flange portion 156. The fifth wall 208 abuts the fourth wall 206 and connects the fourth wall 206 and the sixth wall 210. In some embodiments, the fifth wall 208 is parallel to a portion of the second base surface 200. The sixth wall 210 abuts the crown surface 161 and may be parallel to the second flange portion 156. In other embodiments, such as... Figure 4 As shown, the second recess 202 includes a third wall 198 and a fourth wall 206. The third wall 198 is adjacent to the second base surface 200 and may be parallel to the second flange portion 156. The fourth wall 206 is adjacent to the crown surface 161 and the third wall 198, and may be perpendicular to the second flange portion 156.

[0052] In such Figure 3 In some embodiments shown, the first wall 194 may be parallel to the fourth wall 206, and the third wall 198 may be parallel to the sixth wall 210. Alternatively or additionally, the first wall 194 may be parallel to the sixth wall 210, and the third wall 198 may be parallel to the fourth wall 206. Alternatively or additionally, the distance between the first wall 194 and the first flange portion 154 is the same as the distance between the fourth wall 206 and the second flange portion 156. In some embodiments, such as Figure 4As shown, the first wall 194 may be parallel to the third wall 198. Alternatively, the second wall 196 may be parallel to the fourth wall 206. Alternatively, the distance between the first wall 194 and the first flange portion 154 is the same as the distance between the third wall 198 and the second flange portion 156.

[0053] The adapter 152 is configured to connect to the post-processing component housing 142 at different locations. For example, the adapter 152 may connect to the post-processing component housing 142 at the center of mass of the post-processing component cylinder 140. In another example having more than one post-processing system component 148, the adapter 152 may connect to the post-processing component housing 142 at the midpoint between the outlet of one post-processing system component 148 and the inlet of another post-processing system component 148.

[0054] In some embodiments, the fastener is a clamp 170 (e.g., a hoop, a belt clamp, etc.) that applies compressive force to secure the post-processing component cylinder 140 to the inlet body 106 and the outlet body 128, and suspends the post-processing component cylinder 140 in the post-processing system 100, such as Figure 3 , Figure 5 and Figure 8 As shown. The clamp 170 includes a first clamp flange portion 172. The first clamp flange portion 172 compresses the inlet connection flange portion 120 toward the adapter body 184. In this way, the clamp 170 connects the post-treatment component cylinder 140 to the inlet body 106. The clamp 170 may include bolts and nuts that cooperate to tighten and loosen the clamp 170. The clamp 170 also includes a second clamp flange portion 174. The second clamp flange portion 174 compresses the outlet connection flange portion 136 toward the adapter body 184. In this way, the clamp 170 also connects the post-treatment component cylinder 140 to the outlet body 128. Figure 5 and Figure 8 In the illustrated embodiment, any tolerance variation between the first clamp flange portion 172 and the inlet connection flange portion 120 will have a minor effect on the compression of the first gasket 166 and will have a greater impact than... Figure 3 and Figure 4 The illustrated embodiment provides a more consistent seal. Similarly, any tolerance variation between the second clamp flange portion 174 and the outlet connection flange portion 136 will have a smaller impact on the compression of the second gasket 168 and will have a greater effect than... Figure 3 and Figure 4 The embodiment shown provides a more consistent seal.

[0055] In some embodiments, the clamp 170 includes a belt 176 (e.g., a ring, a strip, etc.). Figures 3 to 5 as well as Figure 8As shown, belt 176 is disposed on the outer surface of clamp 170. Clamp 170 may include a winch (e.g., adjuster, etc.). The winch can be used to attach belt 176 to clamp 170. Therefore, clamp 170 facilitates the suspension of aftertreatment component cylinder 140 within inlet body 106 and outlet body 128. Compared to an aftertreatment system with multiple clamps, each of which must be removed to access the aftertreatment component, by suspending the aftertreatment component cylinder 140 within inlet body 106 and outlet body 128 with clamp 170, the aftertreatment system component 148 is easier to install and remove (e.g., for replacement, for maintenance, etc.). Unlike an aftertreatment system that utilizes multiple clamps to suspend the aftertreatment component, the use of clamp 170 also provides additional mounting space on the exterior of the aftertreatment system 100, which provides a greater overall isolation length and reduces the number of connections and openings from which exhaust gas may escape. III. Example Method for Installing Aftertreatment Component Cylinder Figure 6 An installation process 600 (e.g., method, etc.) for installing the post-treatment component cylinder 140 of the post-treatment system 100 is shown.

The replacement process 700 can be performed by a maintenance technician.

[0062] The replacement process 700 begins in frame 702, where maintenance technicians separate clamp 170 from inlet connection flange portion 120 and outlet connection flange portion 136. Specifically, the first clamp flange portion 172 is separated from inlet connection flange portion 120, and the second clamp flange portion 174 is separated from outlet connection flange portion 136.
