DETAILED DESCRIPTION

[0020] Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and for valve assembly for a mounting bracket lift eye for an exhaust aftertreatment assembly. The various concepts introduced above and discussed in greater detail below may be implemented in any of a number of ways, as the described concepts are not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

I. Overview

[0021] In an engine system, an aftertreatment system may be provided to reduce harmful exhaust gas emissions, such as nitrogen oxides (NOx). The aftertreatment system may be large, heavy, and/or otherwise difficult to position when assembling the engine system. A lift arm, such as a crane (e.g., an overhead crane) or other overhead support or lifting device may be used to position the aftertreatment system relative to the engine such that the aftertreatment system may be coupled to one or more components of the engine system.

[0022] Implementations herein are directed to an aftertreatment system for an engine system. The aftertreatment system includes a mounting bracket having a “lift eye” or lift opening for receiving a portion of a lift arm. The mounting bracket may be disposed at a fist radial side of the aftertreatment system such that the lift opening is axially aligned with a center of gravity of the aftertreatment system. The aftertreatment system may be coupled to one or more components of the engine system, such as the engine and/or a turbocharger. The implementations herein further include methods for assembling the engine system.

[0023] Additional implementations herein are directed to an engine system that includes the aftertreatment system described above. The engine system may include an internal combustion engine, such as a diesel engine, a gasoline engine, a propane engine, etc. or a hybrid engine (e.g., an engine that includes an internal combustion engine and an electric motor). The engine may include a combustion chamber that includes one or more cylinders. The combustion chamber may include a cylinder head that defines a top portion of the combustion chamber. In an example embodiment, the aftertreatment system is coupled to the engine. More specifically, the aftertreatment system is coupled to the cylinder head. The aftertreatment system may be structured to receive the exhaust gas from the engine. In some embodiments, the engine system may include a turbocharger. The aftertreatment system may be structured to receive the exhaust gas from the turbocharger. II. Overview of Example Engine Systems

[0024] FIGS. 1-3 depict an engine system 100 (e.g., for a vehicle, a generator, work equipment, etc.) including an internal combustion engine 101 and an aftertreatment system 110 (e.g., treatment system, etc.). The internal combustion engine (ICE) 101 may be a diesel internal combustion engine, gasoline internal combustion engine, propane internal combustion engine, dual-fuel internal combustion engine, etc. In some embodiments, the ICE 101 may be part of a hybrid engine system that includes the ICE 101 and an electric motor. In an example embodiment, the ICE 101 is a gasoline internal combustion engine. The ICE 101 may include a cylinder head 102. In some embodiments, and as shown in FIGS. 1-3, the engine system 100 includes a turbocharger 104.

[0025] The aftertreatment system 110 is configured to treat exhaust produced by the internal combustion engine 101. Accordingly, the aftertreatment system 110 may be in fluid receiving communication with the ICE 101. In some embodiments, when the engine system 100 includes the turbocharger 104, the aftertreatment system 110 is in fluid receiving communication with the turbocharger 104. In some embodiments, the aftertreatment system 110 may be directly coupled to the turbocharger 104. The aftertreatment system 110 is configured to facilitate treatment of the exhaust. The treatment may facilitate reduction of emission of undesirable components (e.g., nitrogen oxides (NOx), sulfur oxide (SOx), etc.) in the exhaust. The treatment may also or instead facilitate conversion of various oxidation components (e.g., carbon monoxide (CO), hydrocarbons, etc.) of the exhaust into other components (e.g., carbon dioxide (CO2), water vapor, etc.). The treatment may also or instead facilitate removal of particulates (e.g., soot, particulate matter, etc.) from the exhaust.

[0026] The aftertreatment system 110 includes an exhaust conduit system (e.g., line system, pipe system, etc.). The exhaust conduit system is configured to facilitate routing of the exhaust produced by the internal combustion engine 101 throughout the aftertreatment system 110 and to a downstream component and/or to atmosphere (e.g., ambient environment, etc.).

[0027] The aftertreatment system 110 may include one or more sensors. For example, in the example system of Figure 1, the aftertreatment system 110 includes a first sensor 141 and a second sensor 143. The first sensor 141 and/or the second sensor 143 may be coupled to the exhaust aftertreatment system 110. The first sensor 141 and/or the second sensor 143 may be configured to detect information or data regarding operation of the exhaust aftertreatment system 110. The first sensor 141 and/or the second sensor 143 may monitor the characteristics (e.g., contents, temperature, pressure, etc.) of the exhaust within the exhaust aftertreatment system 110. The first sensor 141 and/or the second sensor 143 may also monitor characteristics of various components (e.g., a catalytic converter, a filter, etc.) of the exhaust aftertreatment system 110. For example, the exhaust aftertreatment system 110 may include one or more temperature sensors configured to detect a temperature at a location within the exhaust aftertreatment system 110.

[0028] The aftertreatment system 110 may include a mounting bracket 120. As described in more detail herein with respect to FIGS. 4-6, the mounting bracket may be configured to couple to a connecting bracket 150. The connecting bracket 150 may be configured to couple to one or more components of the engine system 100. For example, and as shown in FIGS. 1-3, the connecting bracket 150 may be coupled to the ICE 101. More specifically, the connecting bracket 150 may be coupled to the cylinder head 102. Thus, the connecting bracket 150 is configured to enable coupling of the aftertreatment system 110 to the ICE 101 (or a component thereof, such as the cylinder head 102).

[0029] The exhaust may be routed to an exhaust pipe 200. In some embodiments, the exhaust pipe 200 may be in fluid providing communication with a downstream component, such as an underfloor aftertreatment system having an underfloor catalyst (not shown). In some embodiments, the exhaust pipe 200 may be configured to route the exhaust to the atmosphere.

[0030] FIGS. 4-6 depict the aftertreatment system 110. The aftertreatment system 110 includes a catalyst housing 112, a first endcap 114, and a shell 116 that includes a second endcap 118, and the mounting bracket 120. In some embodiments, and as shown in FIG. 4, the aftertreatment system 110 also includes a cover 160 disposed around the catalyst housing 112, the first endcap 114, and the shell 116. [0031] The catalyst housing 112 may be substantially cylindrical in shape such that the catalyst housing 112 defines a central axis 180. The catalyst housing 112 is configured to contain one or more catalyst members. In an example embodiment, the catalyst housing 112 contains two catalyst members. The catalyst housing 112 may contain additional and/or alternative components such as a filter, etc. In some embodiments, the catalyst housing 112 includes one or more openings for receiving one or more sensors, such as the first sensor 141 and/or the second sensor 143. For example, the catalyst housing 112 may include a first sensor port 140 and a second sensor port 142. The first sensor port 140 may be configured to receive the first sensor 141, and the second sensor port 142 may be configured to receive the second sensor 143. In some embodiments, the first sensor port 140 and/or the second sensor port 142 are radially aligned with the mounting bracket 120. It should be understood that the catalyst housing 112 may include more or fewer sensor ports depending on the number of sensors desired to be included with the aftertreatment system 110.

[0032] As shown in FIG. 5, the first endcap 114 may be disposed at the first end of the catalyst housing 112. In an example embodiment, the first endcap 114 is fixed to the catalyst housing 112 (e.g., by a welding process, an over-molding process, an additive manufacturing process, or other manufacturing processes). In some embodiments, the first endcap 114 may include a first opening for the sensor port 140.

[0033] The shell 116 may be disposed at a second end of the catalyst housing 112. As briefly described above, the shell 116 includes the second endcap 118 and the mounting bracket 120. In some embodiments, the second endcap 118 is monolithically formed with the mounting bracket 120. The shell 116 may be formed by a casting process where the second endcap 118 and the mounting bracket 120 are formed in by the casting process. In some embodiments, the shell 116 may be formed by a different manufacturing processes such as an additive manufacturing process. The second endcap 118 may be fixed to the catalyst housing 112 (e.g., by a welding process, an over-molding process, an additive manufacturing process, or other manufacturing processes). [0034] The mounting bracket 120 includes a mounting portion 122 and a lift portion 130. The mounting bracket 120 is disposed at a first radial side of the shell 116 such that the mounting bracket 120 is radially aligned with the first sensor port 140 and/or the second sensor port 142.

[0035] As shown in FIGS. 4-6, the mounting portion 122 defines a first mounting opening 124 and a second mounting opening 126. The first mounting opening 124 and the second mounting opening 126 are configured to receive a fastener (e.g., bolt, screw, etc.) shown as a fasteners 152. The fasteners 152 are configured to couple the mounting bracket 120 to the connecting bracket 150.

[0036] The lift portion 130 extends axially and radially away from the mounting portion 122. The lift portion 130 extends radially away from the second endcap 118 and axially towards the first sensor port 140 and/or the second sensor port 142 such that a gap is defined between the catalyst housing 112 and the lift portion 130. In some embodiments, the lift portion includes a ring portion 132 that defines a lift opening 134. The lift opening 134 is configured to receive a portion of a lift arm such that the lift arm is operable to lift the aftertreatment system 110 by engaging the ring portion 132. In some embodiments, the lift portion 130 is axially and radially aligned with a center of gravity of the aftertreatment system 110.

[0037] The connecting bracket 150 is configured to couple the aftertreatment system 110 to the ICE 101. In some embodiments, the connecting bracket 150 is coupled to the mounting bracket 120 by one or more fasteners 152. The connecting bracket 150 may be coupled to the ICE 101, or a component thereof, such as the cylinder head 102.

[0038] The cover 160 is disposed around at least a portion of the catalyst housing 112, the first endcap 114, and/or the shell 116 such that the catalyst housing 112, the first endcap, and the shell 116 are at least partially contained within the cover 160. The cover 160 may be a thermal cover configured to at least partially thermally insulate an interior of the aftertreatment system 110 from an exterior of the aftertreatment system 110. For example, the cover 160 may mitigate heat from transferring radially through the catalyst housing 112, the first endcap, and/or the shell 116. [0039] Now referring to FIGS. 7 and 8 the aftertreatment system 110 is shown with the lifting arm 190, according to an example embodiment. As briefly described above, a portion 191 of the lift arm 190 is received by the lift opening 134. The portion 191 of the lift arm 190 engages with the lift ring 132 to lift the aftertreatment system 110.

[0040] Now referring to FIGS. 9 and 10, an example manufacturing process is shown, according to an example embodiment. As shown, a manufacturing tool shown as a welding device 192 may be used in the manufacturing process. The manufacturing process may include coupling (e.g., welding by the welding device 192) the sensor port 142 to the catalyst housing 112. The sensor port 142 is structured to receive a sensor, such as the sensor 143. For example, the sensor port 142 may include internal threads for threadably coupling to the sensor 143. The lift portion 130 is disposed radially away from the catalyst housing 112 such that the gap defined between the catalyst housing 112 and the lift portion 130 is large enough to receive at least a portion of the welding device 192 therein, when the welding device 192 used to weld the sensor port 142to the catalyst housing 112. More specifically, the welding device 192 is provided, at least partially in the gap defined between the catalyst housing 112 and the lift portion 130 such that a first angle

[0042] In some embodiments a method may include providing the ICE 101, providing the exhaust aftertreatment system 110, engaging, by the portion 191 of a lift arm 190, the lift opening 134 such that the portion 191 of the lift arm 190 is received by the lift opening 134, lifting the exhaust aftertreatment system 110, by the portion 191 of the lift arm 190 received by the lift opening 134, and coupling the exhaust aftertreatment system 110 to the ICE 101 (or a component thereof, such as the cylinder head 102) by the connecting bracket 150. The method may also include disengaging, by the portion 191 of the lift arm 190, the lift opening 134. The method may also include coupling the exhaust aftertreatment system 110 to the turbocharger 104 such that the exhaust aftertreatment system 110 is directly coupled to the turbocharger 104.

[0043] Coupling the shell 116 to the catalyst housing 112 may include welding (e.g., by using the welding device 192) the shell 116 to the catalyst housing 112. The lift portion 130 is disposed radially away from the catalyst housing 112 such that the gap defined between the catalyst housing 112 and the lift portion 130 is large enough to receive at least a portion of the welding device 192 when the welding device 192 used to weld the shell 116 to the catalyst housing 112.
