ABSTRACT:
An engine has a main intake passage having a throttle valve therein. A bypass passage is branched off from the main intake passage located upstream of the throttle valve and is connected to the main intake passage located downstream of the throttle valve. A flow control valve, actuated by a stepper motor, is arranged in the bypass passage. The step position of the stepper motor is so controlled that the idling speed becomes equal to a desired speed. When an engine stall takes place and, then, the engine is started again, the step motor is rotated by five steps in a rotating direction wherein the flow area of the flow control valve is increased.
