のアイドル回転速度制御装置。 A normal control electromagnetic coil that drives the valve opening and an external load electromagnetic coil that drives the valve opening are provided in parallel, and an idle that controls the auxiliary air flow rate of the auxiliary air passage that bypasses the throttle valve. a control valve; a control amount setting means for setting a control amount to control the idle rotation speed based on the engine operating state;
An idling rotational speed of an internal combustion engine comprising a current supply means, an external load detection means for detecting whether or not an external load is applied, and a second current supply means for supplying current to the external load electromagnetic coil when the external load is applied. In the control device, the minimum control amount setting means sets the minimum control amount so that it is smaller when the external load is turned on than when the external load is not turned on; an energization control device that controls the first energization device based on the selected control amount or the minimum control amount; .
