Abstract: A mixer assembly for a vehicle exhaust system includes a mixer shell defining an internal cavity and an inlet reactor positioned within the internal cavity. The inlet reactor has a fluid inlet, a first exhaust gas inlet, and a second exhaust gas inlet. An inlet baffle is mounted to an upstream end of the mixer shell. The inlet baffle includes a first opening that directs exhaust gas into the first exhaust gas inlet, a scoop that directs exhaust gas into the second exhaust gas inlet, and a plurality of bypass openings that direct exhaust gas to bypass entry into the inlet reactor.

Abstract: A component for a mixer of a vehicle exhaust system, according to an exemplary aspect of the present disclosure includes, among other things, a doser mount comprising a curved body having a center boss with a doser opening defining a doser axis. The curved body includes at least a first mating surface configured to receive a first mixer shell defined by a first dimension and a second mating surface configured to receive a second mixer shell defined by a second dimension different than the first dimension.

Abstract: A mixer for a vehicle exhaust system, according to an exemplary aspect of the present disclosure includes, among other things, a mixer outer shell defining an internal cavity configured to receive engine exhaust gases, the mixer outer shell having a first end and a second end opposite the first end. A baffle is associated with one of the first and second ends. The baffle comprises a body that includes at least one sensor area formed within the body.

Abstract: A mixing assembly for an after-treatment unit of an exhaust system of a vehicle. The mixing assembly includes a swirl component and a bowl. The swirl component has a doser opening on a top surface for the ingress of reductant fluid(s) such as urea. The swirl component has a frustoconical portion and a cylindrical portion. The bowl is extended from a bottom surface of the cylindrical portion. Both the frustoconical portion and cylindrical portion of the swirl component are stamped together or formed from a single sheet metal stamping process. The present mixing assembly can substantially reduce the deposit build-ups in the transition between the swirl component and the bowl.
