  • Patent number: 11639698
    Abstract: A dual fuel system includes a liquid pilot fuel supply, a liquid main fuel supply, and a fuel injection apparatus. The dual fuel system further includes a fueling control unit coupled with a cylinder pressure sensor and a NOx sensor, and structured to vary, via outputting a fueling control command to a main fuel injection control valve, fuel delivery parameters each on the basis of at least one of a cylinder pressure parameter or a NOx parameter. The fueling control unit compensates via the varying fuel delivery parameters for a change to a liquid main fuel composition such as a change from a first alcohol fuel or blend to a second alcohol fuel or blend.

  • Patent number: 10287950
    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.

  • Patent number: 9849958
    Abstract: A packaging system for enclosing an aftertreatment module associated with an engine is described. The packaging system includes a housing structure configured to enclose the aftertreatment module therein, the housing structure being coupled to an exhaust conduit of the engine. The housing structure includes a base portion and a plurality of side portions extending from the base portion. The base portion and the plurality of side portions define a chamber for receiving the aftertreatment module therein. Further, the packaging system includes a equipment rack configured to receive one or more components of the accessory system. The equipment rack includes a top end and a bottom end, the top end being distal from the bottom end and configured to couple with the base portion of the housing structure. The bottom end of the equipment rack is supported on a floor.

  • Patent number: 9657618
    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.
