Abstract: An exhaust gas aftertreatment system includes an outlet housing body, an outlet housing fitting, an outlet sampling system, and an outlet sensor. The outlet sampling system includes a sampling bowl and a sampling ring. The sampling bowl is coupled to the outlet housing body and extends away from the outlet housing body so as to define a sampling bowl cavity between the sampling bowl and the outlet housing body. The sampling ring is coupled to the sampling bowl and separated from the outlet housing body by the sampling bowl. The sampling ring is coupled to the outlet housing fitting and defines a sampling ring cavity. The sampling ring includes a plurality of sampling ring inlet apertures and a connector. The sampling ring inlet apertures are each configured to receive exhaust gas from within the outlet housing body and provide the exhaust gas to the sampling ring cavity.

Abstract: A mixing assembly for an exhaust system can include an outer body, a front plate, a back plate, a middle member, and an inner member. The outer body defines an interior volume and has a center axis. The front plate defines an upstream portion of the interior volume and the back plate defines a downstream portion of the interior volume. The middle member is positioned transverse to the center axis and defines a volume. The inner member is positioned coaxially with the middle member inside the middle member. The front plate includes inlets configured to direct exhaust to (i) a first flow path into an interior of the inner member, (ii) a second flow path into the volume of the middle member between a sidewall of the middle member and a sidewall of the inner member, and (iii) a third flow path into the interior volume of the outer body.

Abstract: An aftertreatment component's shape, entrance geometry, and/or position within an aftertreatment assembly can be modified for local and/or bulk exhaust flow control. In some implementations, a body of the aftertreatment component has a non-circular cross-section, a non-circular opening, and/or a variable face geometry. The non-circular cross-section and/or opening can be a variety of different shapes.

Abstract: A decomposition chamber for an exhaust gas aftertreatment system includes an inlet tube, a selective catalytic reduction (SCR) catalyst member, a mixing collector wall, a distribution cap, and a dividing tube. The inlet tube is configured to receive exhaust gas. The mixing collector wall includes a mixing assembly flow aperture. The distribution cap is coupled to the inlet tube and configured to receive the exhaust gas from the inlet tube. The dividing tube is coupled to the mixing collector wall. The dividing tube separates the distribution cap from the mixing assembly flow aperture. The dividing tube includes a first dividing tube inlet aperture that is configured to receive the exhaust gas from the distribution cap. The dividing tube outlet aperture is configured to provide the exhaust gas to the mixing assembly flow aperture.
