Abstract
PURPOSE: To converge reduction of rotational frequency of an engine into a target idle rotational frequency for a short time by enabling drive speed of a throttle valve actuator to be changed over.
CONSTITUTION: When rotational frequency of an engine 1 is reduced lower than a target idle rotational frequency, and return position of a throttle valve (not shown) in a carbureter 2 is detected to be released from control of a throttle actuator 7 by an idle detecting switch 11, a feed-back control for conrolling the idle rotational frequency with a control unit 12 is stopped. At the same time, an actuator 7 is driven with a predetermined speed in the direction of increasing the opening of the throttle valve until the return position of the valve is detected by a limit switch 6 to be controlled by the throttle actuator 7. Thus, when the rotational frequency is reduced, it can be rapidly restored to the target idle rotational frequency.
