ABSTRACT:
An internal combustion engine has an intake system provided with a valve for controlling the intake air flow in an idling operation. There is provided a control system including an engine speed detector and a control circuit which compares the engine speed signal from the engine speed detector with a reference value corresponding to a desired idling speed to produce a feedback signal for adjusting the valve. There is also provided an external load detector for producing a modifying signal when an external load is applied to the engine in the idling operation. The control system functions to interrupt the feedback control under the feedback signal for a predetermined time when the external load is applied or removed so as to stabilize the engine speed in a transient period.
