案登録請求の範囲第１項記載の燃料噴射装置。[Scope of Claim for Utility Model Registration] (1) The fuel injection pump is driven by the fuel injection pump cam installed on the camshaft linked to the engine crankshaft to forcefully feed fuel to the fuel injection valve, and the supply pump water or a mixed liquid of water and oil is fed under high pressure to a pressure accumulator, and the water or mixed liquid stored in this pressure accumulator is sent to the fuel injection valve by opening and closing a control valve, and the water or the mixed liquid of water and oil is fed to the pressure accumulator at high pressure. A fuel injection device characterized in that the liquid mixture is simultaneously injected from the fuel injection valves into the combustion chamber of an engine. (2) A cam separate from the cam for the fuel injection pump is installed on the camshaft, and this cam drives the control valve drive pump, and the hydraulic fluid pumped by the control valve drive pump drives the control valve. In addition to opening and closing, this control valve drive pump is equipped with a hydraulic pressure feed rate control device that adjusts the pumping amount of hydraulic fluid according to the operating conditions of the engine. During operation, the amount of hydraulic pressure sent from the control valve drive pump is increased to lengthen the opening time of the control valve, and during high-load engine operation, the amount of hydraulic pressure sent from the control valve drive pump is decreased to increase the amount of control valve opening. The fuel injection device according to claim 1, characterized in that the valve opening time is shortened.
