装置。 In an engine equipped with a throttle valve that adjusts the amount of intake air and a fuel cut control device that stops fuel supply during deceleration operation of the engine, a throttle valve control device that controls the throttle valve of the engine independently of an accelerator pedal; and fuel cut start operation detection means for detecting the start of the fuel cut operation of the fuel cut control means, and when the fuel cut start operation detection means detects the fuel cut start operation of the fuel cut control means, the fuel cut start operation detecting means detects the start of the fuel cut operation of the fuel cut control means. A fuel supply device for an engine, characterized in that the throttle valve is opened by a throttle valve control means in response to an amount of engine output loss when the engine output decreases due to the fuel cut.
