  • Internal combustion engine having dedicated EGR cylinder(s) with split fuel injection timing
    Patent number: 9845747
    Abstract: A method of controlling fuel injection to the cylinders of an internal combustion engine, the engine having exhaust gas recirculation (EGR) from at least one dedicated EGR (D-EGR) cylinder, with the other cylinders being main cylinders. The D-EGR cylinder is run at a richer equivalence ratio than the main cylinders, with the goal of providing increased H2 and CO in the recirculated exhaust. The rich limit of the D-EGR cylinder is maximized by dividing the fuel injection into multiple fuel injection events, with each fuel injection event occurring during the intake valve lift period of the engine cycle.
