Abstract
A control apparatus of an internal combustion engine is able to effectively suppress vibration occurring upon acceleration of a motor vehicle due to an increase in the torque generated by the engine. The apparatus controls the ignition timing in accordance with variations in the acceleration of the motor vehicle, so as to variably control the torque generated by the engine. Upon the start of variable torque control, a controller controls the opening amount of the throttle valve to be larger than the opening amount originally determined depending upon the current operating conditions of the engine. As a result, the generated torque is allowed to be larger than the normally generated torque during variable torque control, and vibration upon acceleration can be effectively suppressed.
