  • Exhaust elbow component with integrated mount
    Patent number: 9896981
    Abstract: An exhaust elbow component may be located upstream of a decomposition reactor pipe and/or may be integrated with decomposition reactor pipe. The exhaust elbow component includes a mounting area for mounting a dosing module to the exhaust elbow component. The mounting area may be configured to limit the heat transfer from the elbow component to the dosing module via the mounting area. The mounting area may include a boss and one or more mounting legs. The one or more legs and/or the boss may have a surface area for convective cooling of the mounting area. The boss may include an opening through an exterior wall of the exhaust elbow component through which an injection tip of the dosing module may dose reductant into an interior chamber of the exhaust elbow. A central axis of the opening may be substantially coaxial with a central axis of the exhaust gas outlet.

  • Systems and techniques for nozzle cooling of diesel exhaust fluid injection systems
    Patent number: 9719392
    Abstract: A system is provided for delivery of diesel exhaust fluid or other reductant to an injector for release into an engine exhaust aftertreatment system. The injector includes a nozzle assembly that thermally shields the diesel exhaust fluid from the exhaust gas temperatures. A diesel exhaust fluid delivery procedure is also disclosed for nozzle cooling prior to operation of the injector for emissions reduction.
