の燃料噴射装置。[Scope of Claim for Utility Model Registration] A second electric throttle valve is installed on the downstream side of the first throttle valve, which opens and closes in conjunction with the amount of depression of the accelerator pedal. In an engine fuel injection device that injects fuel into the intake passage in the form of a spray, an injection hole is provided at a position close to the upstream side of the second throttle valve so that the fuel in the spray form hits the second throttle valve. A fuel injection device for an engine, characterized in that the fuel injection device is installed in the intake passage so as to be located in the intake passage.
