  • Patent number: 11788454
    Abstract: A mixer assembly for a vehicle exhaust system includes a mixer shell defining an internal cavity, wherein the mixer shell includes an upstream end configured to receive exhaust gases and downstream end. A reactor is positioned within the internal cavity and has a reactor inlet configured to receive injected fluid and a reactor outlet that directs a mixture of exhaust gas and injected fluid into the internal cavity. A flow diverter is associated with the reactor to direct exhaust gas bypassing the reactor to mix with the mixture exiting the reactor outlet prior to exiting the downstream end of the mixer.

  • Patent number: 11680507
    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.

  • Patent number: 11624310
    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.

The reactor has a reactor inlet configured to receive injected fluid and a reactor outlet that directs a mixture of exhaust gas and injected fluid into the internal cavity. An inlet baffle is mounted to the upstream end of the mixer shell. The inlet baffle includes at least one opening that directs exhaust gas into at least one exhaust gas inlet to the reactor and a plurality of bypass openings that direct exhaust gas to bypass entry into the reactor. The inlet baffle includes a crowned portion that curves away from the reactor to provide for an increased open area within the internal cavity between the inlet baffle and the reactor.

  • Publication number: 20220090531
    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.

  • Publication number: 20070240895
    Abstract: An extrudable wiring harness clip has an elongate base for taping the wiring harness clip to a bundle of cables and an integral self expanding head for attaching the bundle of cables to a support panel or the like. The extrudable wiring harness clip has a constant cross section extending from a front face to a rear face that are preferably parallel to each other. The bottom surface of the elongate base is preferably flat or at least not curved in a direction that is parallel to the length of the elongate base. The extrudable wiring harness clip is made by slicing a portion from an extrusion strip.
