ABSTRACT:
An ignition timing controlling system of an engine for controlling a fuel injection flow rate and the ignition timing on the basis of intake air flow rate and an engine rotational speed. The system controls the ignition timing to the maximum ignition advance angle when a throttle valve is fully closed and the fuel injection is stopped as in the course of deceleration, or the throttle valve is fully closed and the fuel injection is stopped after a predetermined times of ignition have been effected, and controls the ignition timing to the optimum ignition advance angle when, thereafter, the fuel injection has returned.
