置。A control valve that opens and closes the high-pressure path that communicates the unit injector's pump chamber and needle chamber is interposed in the middle of the high-pressure path that communicates with the pump chamber and needle chamber, making it possible to control the main injection timing and injection amount. A fuel injection device for an internal combustion engine, characterized in that a pump mechanism capable of pumping a predetermined amount of high-pressure fuel into the needle chamber at a predetermined time is provided to enable pre-injection prior to the main injection. Injection device.
