An aftertreatment system includes a housing and a tube assembly. The housing has a peripheral wall including an outer surface, an inner surface defining a passage configured to receive a flow of exhaust gas, and a peripheral wall aperture. The tube assembly includes a fitting assembly and a conveying tube. The fitting assembly includes a fitting body and a fitting tube. The fitting body includes a fitting body aperture, an upper surface, and a lower surface. The fitting body is inserted within the peripheral wall aperture and coupled to the outer surface. The fitting tube extends from the lower surface and is disposed in the passage and includes a fitting tube aperture at an inner end. The conveying tube is positioned partially within the fitting body aperture and extends outward from the fitting body and includes a conveying tube aperture at an inner end.

Aftertreatment system with tube assembly for pressure sensing

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.

Insulated exhaust gas conduit systems

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.

Systems and methods for mounting an aftertreament system component

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.
