ABSTRACT:
A requested injection time InjT that is necessary for a fuel injector to inject a fuel per one combustion cycle is computed in response to variables of an accelerator manipulated by a driver. An injectable time InjMax per one combustion cycle is computed on the basis of an engine speed, and whether the requested injection time InjT is larger than the injectable time InjMax is determined. Then, when it is positively determined that the requested injection time InjT is larger than the injectable time InjMax, the fuel pump is subjected to load-up operation so as to increase a fuel feed pressure.
