Abstract: An aftertreatment module is disclosed for use with an engine. The aftertreatment module may have an inlet housing at least partially defining an inlet passage for exhaust, and at least one mixer disposed in the inlet passage. The aftertreatment module may also have an outlet housing at least partially defining an outlet passage for exhaust, and a catalyst housing removably connected between the inlet housing and the outlet housing. The aftertreatment module may further have a plurality of catalyst substrates configured to be mounted in the catalyst housing, to receive exhaust from the inlet passage in parallel, and to discharge exhaust to the outlet housing in parallel.

Abstract: A system for uniform flow distribution of a reductant is disclosed. The system includes an injector lance and a diffuser assembly. The injector lance further includes a reductant supply conduit and an injector lance. The reductant supply conduit extends into an internal diameter of an exhaust conduit from a first end of the exhaust conduit towards a second end of the exhaust conduit. The injector lance is in communication with and extends perpendicular to the reductant supply conduit. The injector lance is located along a longitudinal axis of the exhaust conduit. The diffuser assembly is further collocated or integral with the injector lance.

Abstract: A mixing element positioned at an exhaust outlet of a Selective Catalytic Reduction (SCR) module is provided. The mixing element includes a base plate having an upper surface and a lower surface. The base plate is configured to deflect a portion of a flow of a fluid around the upper surface thereof. The mixing element also includes a plurality of vanes attached to the lower surface of the base plate in a spaced apart arrangement. The plurality of vanes is configured to induce a swirling effect in a flow of the fluid received therebetween.
