Abstract:
A control apparatus of an internal combustion engine installed on a motor vehicle, comprising a controller that:determines when the engine is in an acceleration operating state in which vibration occurs, controls an output of the engine when the engine is determined to be in the acceleration operating state in a manner so as to reduce the vibration of the vehicle at the time of acceleration of the vehicle by making a generated torque of the internal combustion engine fluctuate by controlling an ignition timing of the engine; and during a period of time in which the engine is determined to be in the acceleration operating state, the controller controls an opening amount of a throttle valve provided in the engine so that the opening amount is set to a second opening amount that is larger than a first opening amount to which the opening amount would be set if the controller had not determined that the engine was in the acceleration operating state.
