Abstract
The sectional area of an air bypass passage which bypasses a throttle valve in an intake passage of an internal combustion engine is increased or decreased depending upon the difference between the actual rotational speed of the engine and the variable reference rotational speed. The variable reference rotational speed is additionally increased by an incremental value during the starting of the engine.
