徴とするエンジンの燃料供給装置。 An intake valve and a fuel injection valve that injects fuel in the direction of the intake valve are provided downstream of the throttle valve in the intake passage having a throttle valve, and an air nozzle is provided at the fuel injection port of the fuel injection valve. In an engine fuel supply system that promotes atomization of injected fuel by force-feeding air from the throttle valve, the engine communicates with the intake passage on the upstream side of the throttle valve, and has a first idle air valve or an idle speed control valve in the middle. A fuel supply device for an engine, characterized in that a bypass circuit having a bypass circuit is connected to an air nozzle of the fuel injection valve, and the air flowing through the bypass circuit is fuel atomization assist air.
