A valve increases or decreases the amount of fuel returned to the fuel tank, and the fuel injection valve increases or decreases the pressure of the fuel supplied from the fuel supply pump by means of a pressure booster piston that uses hydraulic pressure and consists of a large diameter piston and a small diameter plunger. In a fuel injection device for an internal combustion engine that injects fuel into an engine, a power transmission means having a variable pulley is provided between the fuel supply pump and the crankshaft of the engine, and the output of the crankshaft is transmitted to the fuel supply pump via the power transmission means. A fuel injection device for an internal combustion engine, comprising a control means for driving the fuel supply pump and for controlling a reduction ratio of a variable pulley in a power transmission means so as to change the rotation speed of a fuel supply pump according to a required supply pressure. .
