Size of a gap G in the pressure regulator 20 is determined in such a manner as to be balanced with tension of a spring S, holding fuel in the periphery of the injector 4 to a fixed pressure P2. At a low load when an intake pressure P1 is negative with a small opening of the throttle valve, the fuel pressure P2 decreases with a small injection pressure of the injector 4, decreasing an injection amount per unit time while increasing a fuel injection time. In this way, control accuracy of a flow can be enhanced.
