フエイルセーフ装置。 In an internal combustion engine equipped with an idle speed control device that has an idle control valve in an auxiliary air passage that bypasses an intake throttle valve, and controls the idle speed to feed back the idle speed to a target value by controlling the opening degree of the idle control valve. An opening detection means detects that the opening of the valve is near full open, and the opening detection means detects that the opening of the idle control valve is near full open when warm-up is completed and the idle state is completed. Abnormality determining means for determining an abnormality when detected; and fuel supply stopping means for stopping fuel supply to at least some of the cylinders at a predetermined engine speed or higher based on an abnormality determination output of the abnormality determining means. A fail-safe device for an idle rotation speed control device.
