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 mixing element positioned at an exhaust inlet of a Selective Catalytic Reduction (SCR) module is provided. The mixing element includes a base plate having a plurality of perforations thereon. The mixing element also includes a plurality of vanes connected to the base plate. Each of the plurality of vanes is spaced apart from one another. The plurality of vanes includes a plurality of flaps extending radially from the base plate. Each of the plurality of flaps has a planar configuration. The plurality of vanes also includes a plurality of blades attached to the plurality of flaps. Each of the plurality of blades extends axially with respect to an axis of the exhaust inlet. The blade has a curved configuration.
