料噴射装置。 In a fuel injection device for an internal combustion engine with a supercharger, which promotes atomization of the fuel by causing air to collide with the fuel injected from the fuel injection valve, the pressure accumulator tank for storing compressed air from the supercharger is provided as described above. A passage that is connected to the vicinity of the fuel injection part of the fuel injection valve so as to be communicable and connects the pressure accumulation tank and the vicinity of the fuel injection part is opened at the beginning of acceleration, and the compressed air in the pressure accumulation tank is converted into fuel from the fuel injection valve. A fuel injection device for an internal combustion engine, characterized by being provided with a control valve that injects fuel toward the target.
