ABSTRACT:
A control system for controlling the timing for sparking an engine is adapted to retard a spark timing in a predetermined amount at the time of accelerating. An amount of retarding the spark timing at the time of accelerating is set to be gradually increased and then to be gradually decreased. The retarding amount at the time of accelerating is preferably changed in each spark cycle, namely, in each spark timing.
