ABSTRACT:
A high pressure fuel pump boosts the pressure of fuel to discharge a quantity according to the closing period of an electromagnetic spill valve. A fuel distributor pipe receives and delivers to an in-cylinder injector the fuel discharged from the high pressure fuel pump. A fuel pressure sensor measures a fuel pressure Pt in a fuel distributor pipe. The control of open/closure of the electromagnetic spill valve according to the insufficient fuel pressure with respect to the target pressure of fuel pressure Pt is carried out in a manner similar to that of in-cylinder injection execution even during an in-cylinder injection suppressing period in which fuel is not injected from the in-cylinder injector. Accordingly, fuel pressure can be controlled at high accuracy during the in-cylinder injection suppressing period and subsequent in-cylinder injection resuming time.
