Abstract: A mixer for an exhaust gas aftertreatment system includes an outer circumferential edge that extends in a first plane perpendicular to a longitudinal axis of the mixer, a hub including a flat portion that extends in a second plane perpendicular to the longitudinal axis, the second plane being offset from the first plane in a direction along the longitudinal axis; a plurality of openings, each extending in a region between the hub and the outer circumferential edge of the mixer; and a plurality of fins, each extending from at least one edge of the plurality of openings.

Abstract: An aftertreatment system includes a housing and a tube assembly. The housing has an outer surface and an inner surface, the inner surface defining a passage configured to receive a flow of exhaust gas, the housing including an aperture. The tube assembly includes a fitting assembly. The fitting assembly includes a fitting body including a fitting body aperture, an upward-facing surface, and a downward-facing surface, the fitting body extending through the aperture and coupled to the outer surface, a fitting tube extending from the downward-facing surface and disposed in the passage, the fitting tube including a first linear portion attached to the fitting body, and a bent portion extending from the first linear portion, and a conveying tube positioned partially within the fitting body aperture and extending outward from the fitting body.

Abstract: An exhaust treatment device for an exhaust aftertreatment system includes a housing having a chamber for receiving exhaust gas. The housing extends between a first end and a second end and includes a first exhaust tube at the first end and a second exhaust tube at the second end. The exhaust treatment device includes a tubing fitting for the first exhaust tube at the first end having a fitting body and an annular flange at an exterior of the fitting body. The annular flange has a flange interface configured to face a mating flange of a mating tubing fitting. The tubing fitting includes a mounting bracket that extends from the fitting body configured to be attached to a bracket support. The exhaust treatment device includes a band clamp configured to be coupled to the annular flange to securely couple the annular flange to the mating flange.

Abstract: 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.

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 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.
