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 engine system includes an internal combustion engine having an exhaust system with an SCR aftertreatment mechanism and a urea injector upstream the aftertreatment mechanism. A mixing mechanism is positioned fluidly between the urea injector and the aftertreatment mechanism and includes a turbulator and a swirler structured to increase mixing of the urea and exhaust gases. Related methodology is also disclosed.

Abstract: An aftertreatment system for an engine is provided. The aftertreatment system includes a housing member having a bottom end and a top end. The housing member includes an inlet chamber and an outlet chamber defined adjacent to the bottom end and the top end, respectively. The inlet chamber is configured to receive exhaust gas via an inlet port which is coupled to an exhaust conduit of the engine to receive exhaust gas. The outlet chamber is configured to discharge the exhaust gas via an outlet port which is coupled to an exhaust pipe to discharge exhaust gas. The housing member also includes a catalytic chamber disposed between the inlet chamber and the outlet chamber. The aftertreatment system includes one or more catalyst carrying members disposed within the catalytic chamber. The one or more catalyst carrying members are configured to communicate with the inlet chamber to receive exhaust gas therethrough.
