ABSTRACT:
The flow rate of air passing through an air bypass passage which bypasses a throttle valve in an intake passage of an internal combustion engine during idling is corrected depending upon the atmospheric pressure around the engine. Thus, the idling speed of the engine can be stably controlled even at high altitudes.
