ABSTRACT:
An idling rpm control device for an internal combustion engine for controlling idling rpm of the engine depending upon operating parameters, comprises range detecting means for detecting a range of variations in idling rpm of the engine. According to the invention if an rpm variation range is more than a predetermined value, an air-fuel ratio of mixture is controlled toward a richer mixture and as the result if the range is increased, the air-fuel ratio is controlled toward a leaner mixture, thereby minimizing the rpm variation range to improve operation of a vehicle equipped with the engine.
