ABSTRACT:
An engine ignition timing control system comprises a camshaft angle sensor for detecting specific cam angles and outputting corresponding cam angle signals, a crankshaft angle sensor for detecting specific crank angles and outputting corresponding crank pulse signals, and a control unit for controlling the engine ignition timing on the basis of the cam angle signals and the crank pulse signals. The control unit has an engine starting detector, a crank pulse identifier for identifiying at least two crank pulses on the basis of signals from the cam angle and crank angle sensors, a cyclic period calculator for determining the period corresponding to the angular speed of the crankshaft in accordance with said at least two crank pulses thus identified, and an ignition timing calculator. When the engine starting detector detects engine starting, an ignition signal is outputted in response to a signal from the cam angle sensor, and, when completion of starting is detected, an ignition timing is determined and an ignition signal is outputted by the ignition timing calculator in response to a signal from the crank angle sensor by way of the crank pulse identifier and the cyclic period calculator.
