Abstract
An injector is driven in response to a basic injection pulse signal having a pulse width extracted from an engine rotational speed and an intake air flow rate. It is judged that an engine is in normal operation only after the engine has performed predetermined rotations from a moment at which a throttle valve begins to open. During normal operation of the engine, a time period for limiting a pulse width corresponding to an engine rotational speed is selected, and, after this time period has elapsed, a pulse cut signal is generated to interrupt fuel injection of the injector in spite of the presence of the basic injection pulse signal. The basic fuel injection pulse signal is not cut under a transitional condition of the engine.
