To solve slippage of an air-fuel ratio generated by pulsation of fuel pressure.

In a fuel feed system, fuel in a fuel tank 1 is pressurized by a fuel pump 2, and is supplied to a fuel piping 3. Pressure of fuel which is forcibly supplied to an injector 6 is regulated by a pressure regulator 4. In a main fuel feed system, a returnees system in which a piping returned from a pressure regulator 4 is disused is constructed, and is a system in such a condition that a fuel feed system is closed. In an ECU 30, at least one of cylinder in a multiple cylinder internal combustion engine is set so as to differ the same injection timing from that of the other cylinder in a range were resonance phenomenon of fuel injection by the injector 6 is suppressed. To say concretely, the fuel injection timing of a specified cylinder is transferred to an advance side by a predetermined crank angle (for example, 90° CA). In this case, in a rotating range where fuel pressure is largely pulsated by resonance phenomenon, an interval of fuel injection is not rotated constantly, and fuel pressure pulsation is suppressed.
