ABSTRACT:
The ignition timing of an engine is changed by a predetermined value to cause fluctuations in torque to an output shaft of the engine. Vibrations caused by the fluctuations in torque to an engine block are detected and the ignition timing is controlled so that the vibrations can be reduced to the minimum. Thus, the ignition timing of the engine can be controlled to the optimum condition so that the engine can be operated at the highest condition at all times.
