Abstract
Feedback control is carried out to maintain the idling speed of an internal combustion engine at a desired idling speed determined according to the operating conditions of the engine. When the actual idling speed of the engine significantly falls with respect to the desired idling speed for some reason, the amount of the intake air is increased by a large amount, while when the rotational speed falls to a small extent with respect to the desired idling speed, the amount of the intake air is increased little by little.
