Abstract
A fuel injection start timing is determined based on the engine revolution or the engine load, and a common rail pressure is detected simultaneous to this fuel injection start timing. The fuel injection duration is then calculated based on the detected value of the common rail pressure. By doing this, it is possible to obtain a fuel injection duration that is suited for the common rail pressure at the actual fuel injection start time, resulting in an appropriate injection amount.
