Abstract
The ignition timing of an internal combustion engine is controlled to a fixed value during starting or for a period just after starting. However, if the engine is in a high-speed operating condition, the above control for fixing the ignition timing is interrupted and the ignition timing is controlled to change depending upon the change of the operating conditions of the engine.
