Abstract:
Various systems and method for controlling exhaust gas recirculation (EGR) in an internal combustion engine are provided. In one embodiment, a method includes during a first operating condition, directing exhaust gas from a first cylinder group into an engine air intake stream and directing substantially no exhaust gas from a second cylinder group to the engine air intake stream. The method further includes during a second operating condition, directing exhaust gas from the second cylinder group through a turbocharger bypass into the engine air intake stream and reducing a fuel injection amount of the first cylinder group relative to a fuel injection amount of the second cylinder group.
