Combustion control device for internal combustion engine

摘要

An engine 1 is provided with a fuel injection valve 11 for injecting fuel to be supplied to each of cylinders #1 to #4. An electrical control unit (ECU) 30 increases or decreases both a fuel injection amount and an exhaust gas recirculation (EGR) amount so as to quickly approximate torque variation of the engine 1 to a target value. By increasing or decreasing the fuel injection amount so that the target value of the torque variation is in an area of the EGR amount in which the torque variation does not excessively change with the change of the EGR amount, the torque variation is prevented from being largely displaced from the target value on the increase side.
