Method of feedback-controlling idling speed of internal combustion engine
An idling speed feedback control method is described for use with an internal combustion engine having electrical load equipment and a generator for supplying electric power to the electrical load equipment, the generator being driven by the engine. An idling speed feedback control amount is effected as a function of the difference between an actual engine speed and a target speed. The method comprises: detecting a generating state signal representing a field coil current of the generator; detecting the actual engine speed; determining an electrical load correction value as a function of the generating state signal and the actual engine speed; and correcting the feedback control amount during idling by an amount corresponding to the correction value.
