Abstract: An exhaust gas aftertreatment system includes a housing assembly, a first catalyst member, and a second catalyst member. The housing assembly includes an upstream housing, a decomposition housing, a distributing housing, and a catalyst member housing. The upstream housing is centered on an upstream housing axis. The decomposition housing is coupled to the upstream housing and configured to receive exhaust gas from the upstream housing. The distributing housing is coupled to the decomposition housing and configured to receive the exhaust gas from the decomposition housing. The catalyst member housing is coupled to the distributing housing and configured to receive the exhaust gas from the distributing housing. The catalyst member housing is centered on a catalyst member housing axis that is parallel to the upstream housing axis. The first catalyst member extends within the catalyst member housing.

Abstract: An insulated exhaust gas conduit system includes a first exhaust gas conduit, a second exhaust gas conduit, a first insulation sleeve, and a second insulation sleeve. The first exhaust gas conduit has a first exhaust gas conduit end portion. The second exhaust gas conduit has a second exhaust gas conduit end portion that is configured to engage with the first exhaust gas conduit end portion. The first insulation sleeve includes a first insulation sleeve insulation layer and a first insulation sleeve heat shield. The first insulation sleeve insulation layer is disposed around the first exhaust gas conduit. The first insulation sleeve heat shield is disposed around the first insulation sleeve insulation layer. The first insulation sleeve extends beyond the first exhaust gas conduit end portion. The second insulation sleeve includes a second insulation sleeve insulation layer and a second insulation sleeve heat shield.

Abstract: An apparatus includes a housing defining an internal volume and structured to house aftertreatment component for reducing constituents of an exhaust gas. A noise reducing component is disposed within the internal volume and structured to extend around at least a portion of the aftertreatment component.

Abstract: An aftertreatment system includes an exhaust conduit and a vane plate. The vane plate is located in the exhaust conduit. The vane plate includes a plurality of first vanes. The vane plate includes a plurality of second vanes that intersects the plurality of first vanes. The plurality of first vanes and the plurality of second vanes form a plurality of channels. The vane plate is configured to redirect flow of exhaust gas through the exhaust conduit to be in an axial direction of the exhaust conduit.
