Abstract
A fuel supply cut control device comprising an electronic control unit for controlling the injecting operation of a fuel injector. When the throttle valve is closed to the idling position under an operating state where the engine speed is higher than the cut speed, the fuel injection of the fuel injector is stopped. After this, when the engine speed is reduced below the resume speed, the injecting operation of the fuel injector is started. When the vehicle speed is high, the cut speed and the resume speed are low, and when the vehicle speed is low, the cut speed and the resume speed are high.
