ABSTRACT:
An idling speed adjustment system for an engine, in which a pulse width for corrected fuel injection in the idling operation of the engine is set by adjusting idling adjustment means adapted to be adjusted from outside the system. Subsequently, a pulse width for fuel injection in the idling operation is determined in such a way that a pulse width for basic fuel injection which is set on the basis of a throttle opening degree and engine speed is corrected with several correction values which are set on the basis of detected engine state parameters, and the idling-operation corrected fuel injection pulse width which is set as described above.
