Abstract: An aftertreatment system includes a first mounting plate and a first hanger rod. The first mounting plate includes a first aperture and non-circular recessed portion aligned with the first aperture. The first hanger rod comprises a mounting plate connection portion and a shaft. The mounting plate includes a non-circular mounting head having a portion that is engaged with a portion the non-circular recessed portion so as to prevent rotation of the mounting plate connection relative to the first mounting plate. The shaft extends from the non-circular mounting head through the first aperture.

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 comprising includes a first insulation sleeve 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 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.
