Claims

[Scope of utility model registration request]

A fuel injection valve is provided downstream of an injection control solenoid valve to which fuel is supplied at a predetermined pressure, and the solenoid valve is opened for a time corresponding to the injection amount required at a predetermined fuel injection timing. In the fuel injection device, the fuel injection valve is opened by a fuel pressure of A fuel injection device characterized in that the solenoid valve opens after the opening operation and closes before the opening operation of the next stroke.
