常対策装置。 In an internal combustion engine equipped with an idle speed control device that has an idle control valve in the auxiliary air passage that bypasses the throttle valve, and controls the opening degree of the idle speed control valve, the idle speed is feedback-controlled to a target value. Abnormality detection means for detecting an abnormality in the idle speed control device under at least one condition that the actual value of the idle speed is larger than the target value by a predetermined value or more during feedback control; An abnormality countermeasure device for an idle rotation speed control device, characterized in that it is provided with a fuel supply stop means for stopping fuel supply.
