Abstract: A housing member for enclosing an aftertreatment module of an engine is provided. The housing member includes a base member, a plurality of side members extending from the base member, and a top member coupled to the plurality of side members. The base member, the plurality of side members and the top member are together configured to define an inlet chamber and an outlet chamber. The housing member includes an inlet port defined on at least one of the plurality of side members and configured to communicate with the inlet chamber. The inlet port is coupled to an exhaust conduit of the engine to receive exhaust gas. The housing member includes a plurality of outlet ports defined on the top member and at least one of the plurality of side members. The plurality of outlet ports communicates with the outlet chamber to discharge the exhaust gas from the aftertreatment module.

Abstract: An aftertreatment system for a diesel engine is disclosed. The aftertreatment system may include a first flow conduit configured to convey an exhaust gas stream, and a first diffuser assembly positioned fluidly downstream of the first flow conduit and be configured to increase flow uniformity of the exhaust gas stream. The first diffuser assembly may include a first disperser having a honeycomb structure surrounded by a first outer frame. The first disperser may have a number of cells per square inch defining a first cell density. The aftertreatment system may also include a first selective catalytic reduction cassette positioned fluidly downstream of the first diffuser assembly, and the first selective catalytic reduction cassette may include a selective catalytic reduction catalyst.
