ABSTRACT:
An idling rpm feedback control method for controlling the quantity of supplementary air being supplied to an internal combustion engine, in a feedback manner, responsive to the difference between actual engine rpm and the desired idling rpm. When the engine rpm drops to a predetermined rpm being the upper limit of the desired idling rpm, the above feedback control is initiated. When the engine is decelerated with the throttle valve fully closed, and before the feedback control is started, the supplementary air quantity is controlled in decelerating mode in a predetermined manner while the engine speed drops from a predetermined rpm larger than the upper limit of the desired idling rpm to the same upper limit. In case deceleration is continued without disengagement of the power transmission means of the engine, even if the engine rpm drops below the above upper limit of the desired idling rpm, deceleration mode control of the quantity of supplementary air is continued until the power transmission means is disengaged.
