Abstract
It is intended to automatically correct for ignition timing of the engine and fuel injection timing of the engine even if they changed in the case where the attached position of a cam angle sensor is offset after change of distributors and therefore the reference angle is offset. The crank angle and the cam angle of an engine are detected. The phase difference between these angles is computed. The result is reflected in the ignition timing and the fuel injection timing.
