装置。Fast idle setting that increases the normal idle rotation speed to a higher fast idle rotation speed by a predetermined number of rotations when the load of auxiliary equipment such as a near conditioner is applied, and shutoff that cuts off the fuel supply to the engine during deceleration. In an internal combustion engine equipped with a first idle device, if the fast idle device is not operating, the fuel cutoff recovery rotation speed after the fuel supply cutoff is set to be lower than the first idle rotation speed. A fuel cutoff device for an internal combustion engine, characterized in that the fuel cutoff device for an internal combustion engine is provided with a control means for making a fuel cutoff return rotation speed higher than the first idle rotation speed.
