Abstract: An aftertreatment system may include an exhaust gas passageway and a mixer assembly. The exhaust gas passageway may receive exhaust gas from an engine. The mixer assembly is disposed within the exhaust gas passageway and may include an upstream baffle, a downstream baffle, and a tube extending between and connected to the upstream and downstream baffles. The tube may include an inner surface defining a first flow path through the mixer assembly. The upstream and downstream baffles may be attached to each other, the tube and the exhaust gas passageway. The upstream and downstream baffles may cooperate to define a second flow path through the mixer assembly. The second flow path may extend in a rotational direction around an outer surface of the tube.

Abstract: An exhaust aftertreatment system may include a housing, an aftertreatment device, and a cantilevered flow distributing element. The housing receives exhaust gas output from an engine and has a main body and an exhaust gas inlet that is angled relative to the main body. The flow distributing element is disposed within the housing upstream of the exhaust aftertreatment device and includes a baffle plate and a collar. The baffle plate is attached to an inner wall of the main body. The collar may include a plurality of first apertures, a downstream axial edge and an upstream axial edge. A portion of the downstream axial edge may abut an upstream-facing surface of the baffle plate. The baffle plate may have a plurality of second apertures extending through the upstream-facing surface. The collar may extend across and partially block at least some of the second apertures.

Abstract: A mixer assembly for an exhaust aftertreatment system includes a first support ring. The first support ring defines a plurality of first slots angularly spaced apart from each other. A second support ring spaced apart from the first support ring defines a plurality of second slots angularly spaced apart from each other. A plurality of blades extends between the first support ring and the second support ring. Each of the plurality of blades is coupled to each of the first support ring and the second support ring. Each of the plurality of blades includes a base. The base includes a first connecting portion engaged with a corresponding first slot from the plurality of first slots and a second connecting portion engaged with a corresponding second slot from the plurality of second slots. At least one tab extends outwardly from the base at an angle relative to the base.

Abstract: A method of determining an optimized position for a burner in an exhaust aftertreatment system includes estimating temperature distributions across faces of exhaust treatment devices positioned within parallel paths based on an initial burner position upstream of the parallel paths. A temperature distribution across the faces of the exhaust treatment device is again estimated based on a changed burner position. A difference between the estimates is determined. The changing, estimating and determining steps are repeated to correlate the burner position with a temperature variance across the faces. An optimized burner position is determined based on minimizing the temperature variance across the faces of the exhaust treatment devices.
