[0027] Detailed description

[0028] The following is a more detailed description of various concepts and embodiments related to a bracket assembly for securing components of an aftertreatment system to a structure. The various concepts introduced above and discussed in greater detail below can be implemented in any of a variety of ways, as the described concepts are not limited to any particular embodiment. Examples of specific embodiments and applications are provided primarily for illustrative purposes.

[0029] I. Overview of post-processing systems

[0030] Figure 1 A vehicle system 100 is depicted. The vehicle system 100 includes an internal combustion engine 101. The internal combustion engine 101 is configured to combust fuel and provide exhaust gas. The vehicle system 100 also includes an aftertreatment system 102. As explained in more detail herein, the aftertreatment system 102 is configured to treat the exhaust gas provided by the internal combustion engine 101. The aftertreatment system 102 includes an example reductant delivery system 103 for an exhaust conduit system 104. The aftertreatment system 102 includes the reductant delivery system 103, a particulate filter 106 (e.g., a diesel particulate filter (DPF)), a decomposition chamber 108 (e.g., a reactor, a reactor conduit, a conduit, etc.), and a catalyst component 110 (e.g., an SCR catalyst component, etc.).

[0031] The vehicle system 100 also includes a structure 111 (e.g., a chassis, a frame, an arm, etc.). The structure 111 is configured (e.g., constructed to, capable of, etc.) to support portions of the aftertreatment system 102 (e.g., above the ground, etc.). For example, the structure 111 can be coupled to the particulate filter 106, the decomposition chamber 108, and the catalyst component 110. In some embodiments, the structure 111 is also coupled to the internal combustion engine 101.

[0032] The particulate filter 106 is configured to remove particulate matter, such as soot, from the exhaust gas flowing in the exhaust duct system 104. The particulate filter 106 includes an inlet, at which the exhaust gas is received, and an outlet, at which the exhaust gas exits after substantially filtering the particulate matter from the exhaust gas and / or converting the particulate matter into carbon dioxide. In some embodiments, the particulate filter 106 may be omitted.

[0033] The decomposition chamber 108 is configured to receive exhaust gas from the particulate filter 106 and a reductant (eg, urea, diesel exhaust fluid (DEF), etc.) from the reductant delivery system 103. Urea aqueous solution (UWS), water-soluble urea solution (e.g., AUS32, etc.). When the reducing agent is introduced into the exhaust gas, it is beneficial to reduce the undesirable components in the exhaust gas (e.g., NO x The decomposition chamber 108 includes an inlet and an outlet. The inlet of the decomposition chamber 108 is in fluid communication with the particulate filter 106 to receive the exhaust gas containing NOx emissions. The outlet of the decomposition chamber 108 is for the exhaust gas, NOx emissions, ammonia and / or reductant to flow to the catalyst component 110.

[0034] The dispenser assembly 112 is fluidly coupled to a reductant source 114 (eg, fluidly configured to communicate with the reductant source 114, etc.). The reductant source 114 may include a plurality of reductant sources 114. The reductant source 114 may be, for example, a reductant containing The diesel exhaust fluid tank. The reductant pump 116 (e.g., a supply unit, etc.) is used to pressurize the reductant from the reductant source 114 for delivery to the dispenser assembly 112. In some embodiments, the reductant pump 116 is pressure-controlled (e.g., controlled to obtain a target pressure, etc.). The reductant pump 116 includes a reductant filter 118. Before providing the reductant to the internal components (e.g., piston, vanes, etc.) of the reductant pump 116, the reductant filter 118 first filters (e.g., strains, etc.) the reductant. For example, the reductant filter 118 can inhibit or prevent solids (e.g., solidified reductant, contaminants, etc.) from being transmitted to the internal components of the reductant pump 116. In this way, the reductant filter 118 can facilitate extended desired operation of the reductant pump 116. In some embodiments, the reductant pump 116 is coupled (e.g., fastened, attached, attached, welded, etc.) to the chassis of the vehicle associated with the aftertreatment system 102.

[0035] The distributor assembly 112 includes at least one injector 120. Each injector 120 is configured to distribute the reductant into the exhaust gas at an injection axis 119 (e.g., within the decomposition chamber 108, etc.). The aftertreatment system 102 includes a mixer 121 (e.g., a swirl generating device, a blade plate, an inlet plate, a deflector plate, etc.). At least a portion of the mixer 121 can be located within the decomposition chamber 108. However, at least a portion of the mixer 121 can also be located in a conduit of the exhaust conduit system 104 (e.g., a conduit upstream of the decomposition chamber 108, etc.). The mixer 121 is configured to receive the exhaust gas from the decomposition chamber 108 and the reductant from the injector 120, such that the injection axis 119 extends into the mixer 121. The mixer 121 is also configured to promote mixing of the exhaust gas and the reductant. The mixer 121 is configured to promote swirl (e.g., tumbling, rotation, etc.) of the exhaust gas and mixing (e.g., combining, etc.) of the exhaust gas and the reductant so as to disperse the reductant within the exhaust gas downstream of the mixer 121. By using the mixer 121 to disperse the reductant within the exhaust gas (e.g., to obtain an increased homogeneity index, etc.), the reduction of emissions of undesirable components in the exhaust gas is enhanced or the temperature of the exhaust gas can be increased.

[0036] When the injection axis 119 extends into the mixer 121, the injection axis 119 can extend into the mixer 121 at an angle relative to the central axis of the mixer 121. For example, in some embodiments, the injection axis 119 can coincide with the central axis of the mixer 121. In other embodiments, the injection axis 119 can be perpendicular to the central axis of the mixer 121. In yet another embodiment, the injection axis 119 can be parallel to the central axis of the mixer 121.

[0037] In some embodiments, the ejector 120 is not directly coupled to the mixer 121. In these embodiments, the ejector 120 and the mixer 121 can each be coupled to the same component (e.g., a panel, a chamber, etc.). In other embodiments, the ejector 120 is directly coupled to the mixer 121. In these embodiments, the ejector 120 and the mixer 121 can each be coupled to the same component. In some embodiments, the ejector 120 is not disposed within the mixer 121. In other embodiments, the ejector 120 can be at least partially disposed within the mixer 121.

[0038] In some embodiments, the reductant delivery system 103 further includes an air pump 122. In these embodiments, the air pump 122 draws air from an air source 124 (e.g., an air intake, etc.) and passes the air through an air filter 126 disposed upstream of the air pump 122. Additionally, the air pump 122 provides air to the dispenser assembly 112 via a conduit. In these embodiments, the dispenser assembly 112 is configured to mix air and reductant into an air-reductant mixture and provide the air-reductant mixture to the decomposition chamber 108. In other embodiments, the reductant delivery system 103 does not include the air pump 122 or the air source 124. In such embodiments, the dispenser assembly 112 is not configured to mix the reductant with air.

[0039] The doser assembly 112 and the reductant pump 116 are also electrically or communicatively coupled to a reductant delivery system controller 128. The reductant delivery system controller 128 controls the doser assembly 112 to dispense reductant into the decomposition chamber 108. The reductant delivery system controller 128 may also control the reductant pump 116.

[0040] The reductant delivery system controller 128 includes a processing circuit 130. The processing circuit 130 includes a processor 132 and a memory 134. The processor 132 may include a microprocessor, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., or a combination thereof. The memory 134 may include, but is not limited to, an electronic, optical, magnetic, or any other storage or transmission device capable of providing program instructions to the processor, ASIC, FPGA, etc. The memory 134 may include a memory chip, an electrically erasable programmable read-only memory (EEPROM), an erasable programmable read-only memory (EPROM), a flash memory, or any other suitable memory from which the reductant delivery system controller 128 can read instructions. The instructions may include code from any suitable programming language. The memory 134 may include a variety of modules that include instructions configured to be implemented by the processor 132.

[0041] In various embodiments, the reductant delivery system controller 128 is configured to communicate with a central controller 136 (e.g., an engine control unit (ECU), an engine control module (ECM), etc.) of the internal combustion engine having the aftertreatment system 102. In some embodiments, the central controller 136 and the reductant delivery system controller 128 are integrated into a single controller.

[0042] In some embodiments, the central controller 136 may communicate with a display device (e.g., a screen, monitor, touch screen, heads-up display (HUD), indicator light, etc.). The display device may be configured to change state in response to receiving information from the central controller 136. For example, the display device may be configured to change between a static state (e.g., displaying a green light, displaying a "system OK" message, etc.) and an alarm state (e.g., displaying a flashing red light, displaying a "maintenance required" message, etc.) based on communications from the central controller 136. By changing state, the display device may provide an indication to a user (e.g., an operator, etc.) of the state (e.g., operational, maintenance required, etc.) of the reductant delivery system 103.

[0043] The decomposition chamber 108 is located upstream of the catalyst member 110. As a result, the reductant is injected upstream of the catalyst member 110, so that the catalyst member 110 receives a mixture of the reductant and the exhaust gas. The reductant droplets undergo evaporation, pyrolysis, and hydrolysis processes to form non-NOx emissions (e.g., gaseous ammonia, etc.) within the exhaust conduit system 104.

[0044] The catalyst component 110 includes an inlet and an outlet. The inlet of the catalyst component 110 is in fluid communication with the decomposition chamber 108 , from which exhaust gas and reductant are received. The outlet of the catalyst component 110 is in fluid communication with one end of the exhaust conduit system 104 .

[0045] Aftertreatment system 102 may also include an oxidation catalyst component (eg, a diesel oxidation catalyst (DOC)) in fluid communication with exhaust conduit system 104 (eg, downstream of catalyst component 110 or upstream of particulate filter 106 ) to oxidize carbon monoxide in the exhaust gas.

[0046] In some embodiments, the particulate filter 106 can be positioned downstream of the decomposition chamber 108. For example, the particulate filter 106 and the catalyst member 110 can be combined into a single unit. In some embodiments, the doser assembly 112 can alternatively be positioned downstream of the turbocharger or upstream of the turbocharger.

[0047] The aftertreatment system 102 also includes a dispenser mounting bracket 138 (e.g., a mounting bracket, a coupler, a plate, etc.). The dispenser mounting bracket 138 couples the dispenser assembly 112 to components of the aftertreatment system 102. The dispenser mounting bracket 138 is configured to reduce heat transfer from exhaust gas passing through the exhaust duct system 104 to the dispenser assembly 112. In this manner, the dispenser assembly 112 can operate more efficiently and optimally than other dispenser assemblies that do not reduce heat transfer. Additionally, the dispenser mounting bracket 138 is configured to facilitate reliable installation of the dispenser assembly 112. This can reduce manufacturing costs associated with the aftertreatment system 102 and ensure repeatable, desired installation of the dispenser assembly 112.

[0048] In various embodiments, a dispenser mounting bracket 138 couples the dispenser assembly 112 to the decomposition chamber 108. In some embodiments, the dispenser mounting bracket 138 couples the dispenser assembly 112 to an exhaust duct of the exhaust duct system 104. For example, the dispenser mounting bracket 138 can couple the dispenser assembly 112 to an exhaust duct of the exhaust duct system 104 located upstream of the decomposition chamber 108, or to an exhaust duct of the exhaust duct system 104 located downstream of the decomposition chamber 108. In some embodiments, the dispenser mounting bracket 138 couples the dispenser assembly 112 to the particulate filter 106 and / or the catalyst member 110. The location of the dispenser mounting bracket 138 can vary depending on the application of the aftertreatment system 102. For example, in some aftertreatment systems 102, the dispenser mounting bracket 138 can be located further upstream than in other aftertreatment systems 102. Furthermore, some aftertreatment systems 102 can include multiple dispenser assemblies 112, and therefore, multiple dispenser mounting brackets 138.

[0049] II. Overview of Aftertreatment Systems Including Bracket Assemblies

[0050] Various methods of mounting aftertreatment systems may be used to secure the aftertreatment to structure within an internal combustion engine system.

[0051] The aftertreatment system is also connected to an exhaust inlet and outlet. Exhaust gas flows into the aftertreatment system through the inlet. Treated exhaust gas flows out of the aftertreatment system through the outlet. The inlet and outlet are fixed locations within the vehicle system. Therefore, the aftertreatment system is positioned and installed within the vehicle system based on the locations of the inlet and outlet.

[0052] The aftertreatment system can be mounted to the structure at a bottom portion of the exterior of the aftertreatment system. According to this embodiment, the position of the aftertreatment system can be adjusted in only a single direction. For example, the aftertreatment system can only be mounted in different positions along the vertical plane.

[0053] Some embodiments herein relate to a vehicle system including an aftertreatment system. The aftertreatment system includes a bracket assembly. The bracket assembly is coupled to the aftertreatment system and a structure within the vehicle system. The bracket assembly includes a base bracket. The base bracket is coupled to the aftertreatment system and the structure. The base bracket includes a first base flange and a second base flange. The first base flange includes a first base flange slot positioned in a first direction. The second base flange includes a second base flange slot positioned in the first direction and aligned with the first base flange slot. The first base flange slot and the second base flange slot are aligned so that components, such as bolts, can be inserted through the first base flange slot and the second base flange slot. The first base flange slot and the second base flange slot are aligned in the first direction to allow the base flange to be adjusted to various positions. Having the ability to adjust the base flange is important for being able to install the aftertreatment system so that the aftertreatment system is aligned with fixed inlets and outlets.

[0054] The bracket assembly also includes a mounting bracket. The mounting bracket is directly coupled to the aftertreatment system. The mounting bracket is also coupled to the base bracket. The base bracket is configured to receive the mounting bracket. Bolts can be placed through the first base flange slot, the first mounting flange slot, the second mounting flange slot, and the second base flange slot. The bolts secure the base flange to the mounting flange. Connecting the mounting bracket to the base bracket is important for securing the aftertreatment system to the structure. The mounting flange includes a first mounting flange, a second mounting flange, and a mounting wall. The mounting wall extends from the first mounting flange to the second mounting flange. The mounting wall couples the first mounting flange to the second mounting flange. The mounting wall is important because it couples the first and second flanges to the aftertreatment system. The first mounting flange includes a first mounting flange slot positioned in a second direction. The second mounting flange includes a second mounting flange slot positioned in the second direction and aligned with the first mounting flange slot. The first and second mounting flange slots align in the second direction to allow the mounting flanges to be adjusted to various positions. The first and second mounting flange slots allow the mounting flanges to be adjusted to different positions. The first orientation of the first base flange slot and the second base flange slot is different from the second orientation of the first mounting flange slot and the second mounting flange slot. The first orientation can be perpendicular to the second orientation. In other embodiments, the first orientation can be offset from the second orientation by a certain angle. Importantly, the first orientation is different from, for example, offset from, the second orientation, allowing the aftertreatment system to be adjusted in two different orientations. Advantageously, the bracket assembly can be adjusted in two different orientations, allowing the aftertreatment system to be installed in alignment with the fixed inlet and outlet.

[0055] Some embodiments herein also relate to a vehicle system including an aftertreatment system, the aftertreatment system including a bracket assembly having a first strap. The strap is positioned on a mounting bracket wall such that the strap overlaps the mounting bracket wall. The first strap is positioned around the aftertreatment system. The first strap couples the aftertreatment system to the mounting bracket. The first strap is adjustable so that it can be loosened or tightened around the aftertreatment system. This is important to ensure that the aftertreatment system is securely coupled to the mounting bracket.

[0056] Some embodiments herein also relate to an aftertreatment system including a bracket assembly. According to this embodiment, the bracket assembly includes a base bracket, a first mounting bracket, a second mounting bracket, and a first strap. The base bracket extends to include a first base bracket portion and a second base bracket portion. The second base bracket portion extends away from the first base bracket portion so as to be formed around a circular object, such as an aftertreatment system. The second base bracket portion includes a third base flange slot and a fourth base flange slot oriented in a third direction. The third direction is opposite to the first direction. The second mounting bracket includes a second mounting bracket first flange, a second mounting bracket second flange, and a second mounting wall. The second mounting wall extends from the second mounting bracket first flange to the second mounting bracket second flange. The second mounting bracket first flange includes a second mounting flange first slot, and the second mounting bracket second flange includes a second mounting flange second slot. The second mounting bracket first flange slot and the second mounting bracket second flange second slot extend in a fourth direction. The fourth direction may be opposite to the second direction. The base flange is configured to receive the first mounting bracket and the second mounting bracket. The first mounting flange slot overlaps with the first base flange slot, and the second mounting flange slot overlaps with the second base flange slot. The second mounting bracket first flange slot overlaps with the third base flange slot, and the second mounting bracket second flange slot overlaps with the fourth base flange slot. The first and second base flange slots in the first direction, the first and second mounting flange slots in the second direction, the third and other base flange slots in the third direction, and the second mounting flange first slot and second mounting flange second slot in the fourth direction all allow the bracket assembly to be adjusted in two different directions.

[0057] III. Bracket Assembly

[0058] Figures 2 to 14 The aftertreatment system 102 and portions of the aftertreatment system 102 are shown according to various embodiments.

[0059] First embodiment

[0060] Figure 1 Aftertreatment system 102 and bracket assembly 200 are shown. Bracket assembly 200 couples aftertreatment system 102 to structure 111. Bracket assembly 200 is important because it allows aftertreatment system 102 to be mounted to structure 111 at various angles and positions. Bracket assembly 200 allows aftertreatment system 102 to be adjustably mounted to structure 111, which can account for minor variations in vehicle system 100.

[0061] Bracket assembly 200 includes a base bracket 202. Base bracket 202 is coupled to structure 111. Base bracket 202 is configured to secure bracket assembly 200 to the structure. Base bracket 202 includes a first base flange 204 and a second base flange 206. First base flange 204 and second base flange 206 extend from base bracket 202 in a first flange direction. First base flange 204 is positioned a distance from second base flange 206.

[0062] The bracket assembly 200 also includes a base bracket wall 208. The base bracket wall 208 extends from the first base flange 204 to the second base flange 206. The base bracket wall 208 can be perpendicular to the first base flange 204 and the second base flange 206. The base bracket wall 208 is configured to couple the first base flange 204 to the second base flange 206. According to this embodiment, the base bracket wall 208 is flat. In other embodiments, the base bracket wall 208 is curved or angled. It may be advantageous to curve the base bracket wall to accommodate other components of the vehicle system 100.

[0063] The first base flange 204 includes a first base flange slot 210 . The first base flange slot 210 extends along a first direction. The first base flange slot 210 is configured to receive a component (eg, a bolt, a screw, etc.). For example, a bolt can be inserted through the first base flange slot 210 .

[0064] The second base flange 206 includes a second base flange slot 212. The second base flange slot 212 extends along the first direction. For example, the second base flange slot 212 can be aligned with the first base flange slot 210. For example, components (e.g., bolts, screws, etc.) can be placed through the first base flange slot 210 and the second base flange slot 212.

[0065] The bracket assembly 200 according to this embodiment also includes a first mounting bracket 214. The first mounting bracket 214 includes a first mounting flange 216, a second mounting flange 218, and a mounting bracket wall 220. The mounting bracket wall 220 extends from the first mounting flange 216 to the second mounting flange 218. According to this embodiment, the mounting bracket wall 220 is curved and has a first radius of curvature R1. The curved mounting bracket wall 220 enables the first mounting bracket 214 to uniformly apply force to a circular component (e.g., the aftertreatment system 102).

[0066] In other embodiments, the mounting bracket wall 220 may be flat. For example, the mounting bracket wall 220 may be perpendicular to the first mounting flange 216 and the second mounting flange 218. In this embodiment, the mounting bracket wall 220 may be configured to receive a flat surface of the aftertreatment system 102.

[0067] The first mounting flange 216 includes a first mounting flange slot 222 extending in a second direction. The second direction can be different from the first direction. For example, the first base flange slot 210 and the second base flange slot 212 can extend in the first direction, while the first mounting flange slot 222 can extend in the second direction, where the second direction deviates from the first direction (e.g., the second direction is rotated 90 degrees, etc.). For example, the first direction can be transverse to the second direction (e.g., perpendicular). This can be advantageous, for example, to adjust the mounting position of the aftertreatment system 102 in two different directions.

[0068] The second mounting flange 218 includes a second mounting flange slot 226. The second mounting flange slot 226 extends in the second direction. The second mounting flange slot 226 can be aligned with the first mounting flange slot 222. For example, the first mounting flange slot 222 and the second mounting flange slot 226 are positioned parallel to each other.

[0069] The base bracket 202 is configured to receive a first mounting bracket 214. The first base flange 204 can be positioned proximate (e.g., adjacent) to the first mounting flange 216, and the second base flange 206 can be positioned proximate to the second mounting flange 218. According to this embodiment, a portion of the first base flange slot 210 can overlap a portion of the first mounting flange slot 222. For example, when the first mounting bracket 214 is received by the base bracket 202, the first base flange 204 is in a facing relationship with the first mounting flange 216. For example, the first base flange slot 210 can overlap with the first mounting flange slot 222, allowing an object (e.g., a bolt, screw, etc.) to be inserted through the opening created by the overlap of the first base flange slot 210 and the first mounting flange slot 222. The overlap of the first base flange slot 210 and the first mounting flange slot 222 allows the first base flange slot 210 and the first mounting flange slot 222 to be simultaneously adjusted relative to each other in two directions. For example, the first base flange slot 210 and the first mounting flange slot 222 may be adjusted relative to each other in the Y-direction and the Z-direction.

[0070] Furthermore, when first mounting bracket 214 is positioned with base bracket 202, a portion of second base flange slot 212 overlaps a portion of second mounting flange slot 226. According to this embodiment, a portion of first base flange slot 210 can overlap a portion of first mounting flange slot 222. For example, when first mounting bracket 214 is received by base bracket 202, second base flange 206 and second mounting flange 218 are in a facing relationship. For example, second base flange slot 212 can overlap second mounting flange slot 226, allowing an object (e.g., a bolt, screw, etc.) to be inserted through the opening created by the overlap between second base flange slot 212 and second mounting flange slot 226. The overlap between second base flange slot 212 and second mounting flange slot 226 also allows second base flange slot 212 and second mounting flange slot 226 to be simultaneously adjusted relative to each other in two directions. For example, second base flange slot 212 and second mounting flange slot 226 can be adjusted relative to each other in a first direction (e.g., the Y direction, etc.) and a second direction (e.g., the Z direction, etc.).

[0071] Figure 2 An embodiment of an aftertreatment system 102 is shown. The aftertreatment system 102 includes a bracket assembly 200. According to this embodiment, the bracket assembly 200 may include a plurality of bracket assemblies 200. For example, according to this embodiment, the aftertreatment system may be secured to a structure via a plurality of base brackets 202 and a plurality of first mounting brackets 214. For example, the bracket assembly 200 may include two base brackets 202 and two first mounting brackets 214. For example, the first base bracket 202 and the second base bracket 202 may be positioned a distance from each other along a plane defined by a base bracket wall 208.

[0072] Bracket assembly 200 also includes a first strap 228. First strap 228 is positioned around aftertreatment system 102. First strap 228 is positioned between first mounting flange 216 and second mounting flange 218, overlapping mounting bracket wall 220. First strap 228 extends between first mounting flange 216 and second mounting flange 218. First strap 228 is configured to secure aftertreatment system 102 to first mounting bracket 214.

[0073] According to various embodiments, Figure 2 and Figure 3As shown, first mounting flange 216 is positioned on the inner side of first base flange 204, and second mounting flange 218 is positioned on the inner side of second base flange 206. First base flange 204 and first mounting flange 216 are positioned such that first base flange slot 210 and first mounting flange slot 222 partially overlap, thereby defining first opening 230. The position of first opening 230 can be varied. For example, first base flange slot 210 and first mounting flange slot 222 can be adjusted relative to each other so that the position of first opening 230 can be shifted in two directions (e.g., Y and Z directions, etc.).

[0074] The second base flange 206 and the second mounting flange 218 are positioned such that the second base flange slot 212 and the second mounting flange slot 226 partially overlap to define a second opening 232. The position of the second opening 232 can be varied. For example, the second base flange slot 212 and the second mounting flange slot 226 can be adjusted relative to each other so that the position of the second opening 232 can be shifted in two directions (e.g., the Y direction and the Z direction).

[0075] Now refer to Figures 4 to 6 , is based on Figure 2 and Figure 3 . The bracket assembly 200 of the first embodiment is shown in FIG. The bracket assembly 200 also includes a plurality of bolts 234. For example, the first bolt 234 can be positioned within the first opening 230 and the second opening 232. The plurality of bolts 234 are configured to secure the first mounting bracket 214 to the base bracket 202. According to this embodiment, the first strap 228 is adjustable. In some embodiments, the first strap 228 can be a rigid, non-flexible material (e.g., metal, aluminum, steel, etc.). It may be advantageous for the first strap 228 to be constructed of a rigid material (e.g., aluminum) to secure the aftertreatment system 102 to the structure 111 without deforming the first strap 228. In other embodiments, the first strap 228 can be a flexible material (e.g., a polymer, nylon, etc.). It may be advantageous for the first strap 228 to be flexible to secure the first strap 228 to an object of uneven shape. For example, if first strap 228 is flexible, the first strap may fit securely to various shapes and may conform to the shape of an object to secure the object to structure 111 via bracket assembly 200 .

[0076] According to this embodiment, the bracket assembly 200 further includes an adjustable buckle 402. The adjustable buckle 402 is configured to loosen and tighten the first strap 228 around the aftertreatment system 102. The adjustable buckle 402 includes a screw 404. The screw 404 is configured to tighten and loosen the adjustable buckle 402. For example, when placing the first strap 228 around the aftertreatment system 102, the adjustable buckle 402 can be loosened. Once the first strap 228 is placed in the desired position around the aftertreatment system 102, the user can tighten the screw 404 to tighten the first strap 228.

[0077] The first strap 228 includes a first strap first end 406 and a first strap second end 408. The adjustable buckle 402 is coupled to the first strap first end 406 and the first strap second end 408. The adjustable buckle 402 is configured to adjust the first strap 228. For example, when the screw 404 is tightened, the adjustable buckle 402 pulls the first strap first end 406 and the first strap second end 408 closer together to secure the first strap 228 around the aftertreatment system 102.

[0078] Now refer to Figure 7 ,yes Figures 2 to 6 An exploded view of the bracket assembly 200 of the embodiment of FIG. Figure 7 As shown, the first strap 228 is positioned on the mounting bracket wall 220. The base bracket 202 is configured to receive the first mounting bracket 214. Once received, the bolts 234 are configured to secure the first mounting bracket 214 to the base bracket 202.

[0079] The bracket assembly 200 also includes a plurality of nuts 702. The nuts 702 are positioned on distal ends of the bolts 234. For example, once the bolts 234 are positioned within the first opening 230 and the second opening 232, the bolts 234 are threadedly threaded through the nuts 702. The nuts 702 are configured to secure the bolts 234 within the first opening 230 and the second opening 232. For example, the nuts 702 are configured to prevent the bolts 234 from moving out (e.g., falling out, etc.) of the first opening 230 and the second opening 232.

Figure 10As shown, the base support wall 208 includes a base support first end 802 and a base support second end 804. According to this embodiment, the base support wall 208 is curved (e.g., bent at an angle, including a radius of curvature, etc.). For example, if the base support first end 802 is positioned on a first plane extending along a first base direction, the base support second end 804 can protrude outwardly from the base support first end 802 at an angle and extend along a second base direction, thereby defining a circular interior that follows the curvature of the first strip 228. The circular interior of the base support 202 is configured to receive the curved mounting bracket 214 to correspond to the curved aftertreatment system 102.

[0082] First base flange 204 also includes a third base flange groove 806. Third base flange groove 806 extends in the third direction.

The second mounting bracket wall 816 extends from the second mounting bracket first flange 812 to the second mounting bracket second flange 814. According to this embodiment, the second mounting bracket wall 816 is curved. For example, the second mounting bracket wall 816 includes a second radius of curvature. In some embodiments, the second radius of curvature R2 can be equal to the first radius of curvature. In other embodiments, the second radius of curvature R2 of the second mounting bracket wall 816 can be greater than or less than the first radius of curvature R1 of the mounting bracket wall 220.

[0084] In other embodiments, both the mounting bracket wall 220 and the second mounting bracket wall 816 can be flat (e.g., without curvature, etc.). This embodiment can be advantageous, for example, when securing an object having a flat surface (e.g., cube-shaped, box-shaped, etc.) to a structure.

[0085] In another embodiment, second mounting bracket wall 816 may be flat while mounting bracket wall 220 is curved. This embodiment may be advantageous, for example, when second mounting bracket wall 816 may be coupled to a flat surface of a component (e.g., a support structure) while mounting bracket wall 220 may be coupled to a curved structure (e.g., an aftertreatment system).

[0086] Furthermore, the first strap 228 overlaps the first mounting bracket wall 220 and the second mounting bracket wall 816. The first strap is configured to secure the object (the aftertreatment system 102) to the first mounting bracket 214 and the second mounting bracket 810. The first mounting bracket 214 and the second mounting bracket 810 can then be coupled to the base bracket 202. Thus, the base bracket 202 can then be coupled to the structure 111 (e.g., a structure within the vehicle system 100, etc.) so that the aftertreatment system does not move within the vehicle system 100.

[0087] Second mounting bracket first flange 812 includes second mounting bracket first flange slot 818. Second mounting bracket first flange slot 818 extends in the fourth direction. Second mounting bracket second flange 814 includes second mounting bracket second flange slot 820.
