する蓄圧式燃料筒内直接噴射装置。 In a fuel injection device in which an electromagnetically controlled injector is arranged in each cylinder of a gasoline engine, fuel in a fuel tank is accumulated in a pressure accumulator by a fuel pump, and this accumulated fuel is force-fed to each electromagnetically controlled injector. A bypass passage is provided on the discharge side of the high-pressure discharge type fuel pump to directly pump fuel to the electromagnetically controlled injector without passing through the pressure accumulator, and a portion of this bypass passage is connected to the pressure accumulator via an orifice. This is a pressure accumulation type fuel cylinder direct injection device that is characterized by:
