Abstract: An aftertreatment module for use with an engine is disclosed. The aftertreatment module may include a housing having an inlet configured to direct exhaust in a first flow direction into the aftertreatment module, and an outlet configured to direct exhaust in the first flow direction out of the aftertreatment module. The aftertreatment module may also include a catalyst bank separating the inlet from the outlet. The catalyst bank may have a face disposed at an oblique angle with respect to the first flow direction. The oblique angle may create an inlet passage extending from the inlet to the catalyst bank and having a decreasing cross-sectional area, and an outlet passage extending from the catalyst bank to the outlet and having an increasing cross-sectional area.

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.
