  • Patent number: 10030617
    Abstract: Various methods for controlling EGR rate are disclosed. In one embodiment, a method comprises routing at least a portion of exhaust from a first exhaust manifold to an intake manifold, and not to atmosphere, the first exhaust manifold exclusively coupled to a first cylinder group. The method further includes routing exhaust from at least one additional exhaust manifold coupled to a corresponding at least one additional cylinder group to atmosphere, and during a first engine operating condition where an engine fuel demand is below a threshold demand, not injecting fuel to each of a subset of cylinders in the first cylinder group while injecting fuel to a subset of all cylinders coupled to the at least one additional exhaust manifold, where a number of cylinders of the subset of cylinders in the first cylinder group decreases in response to an increase in a target EGR rate.

  • Patent number: 9316165
    Abstract: Various methods for controlling EGR rate are disclosed. In one embodiment, a method for controlling EGR rate in an engine comprises routing exhaust from a first cylinder group to an intake coupled to the engine, and not to atmosphere, routing exhaust from a second cylinder group to atmosphere, and, during a first engine operating condition, injecting fuel to each cylinder in the first cylinder group while injecting fuel to a subset of cylinders of the second cylinder group.

  • Patent number: 9109545
    Abstract: Various systems and method for controlling exhaust gas recirculation in an internal combustion engine are provided. In one embodiment, a method for controlling an engine includes determining an actual intake oxygen concentration, adjusting a donor cylinder fuel injection amount to drive the actual intake oxygen concentration to a designated intake oxygen concentration, and adjusting a non-donor cylinder fuel injection amount dependent upon the donor cylinder fuel injection adjustment and to maintain a second operating parameter.
