Abstract:
A combustion control device for an internal combustion engine, comprising:fuel injection means for injecting fuel into a cylinder of the internal combustion engine;exhaust gas recirculation means for recirculating part of exhaust gas exhausted from an exhaust system of the internal combustion engine to an intake system of the internal combustion engine;output variation detection means for detecting output variation of the internal combustion engine; andcontrol means for correcting a fuel injection amount injected by the fuel injection means incrementally immediately when the output variation detected by the output variation detection means exceeds a target value so as to approximate the output variation to the target value, and correcting an exhaust gas amount to be recirculated by the exhaust gas recirculation means decrementally when the output variation detected by the output variation detection means is greater than the target value so as to approximate the output variation to the target value.
