ABSTRACT:
The flow rate of intake air sucked into an internal combustion engine when a throttle valve of the engine is at the idling position is controlled so that the actual rotational speed of the engine becomes equal to a desired rotational speed of the engine. This desired rotational speed of the engine is determined by a predetermined calculation, in accordances with the warming-up state of the engine.
