ABSTRACT:
A fuel delivery system is disclosed in which fuel pressure at a fuel rail is controlled by controlling electrical power applied to an electric fuel pump. The fuel pressure is controlled to maintain the minimum value required to meet two constraints. The first constraint is the quantity of desired fuel to be delivered by the injectors at wide-open throttle as a function of engine speed. The second constraint is to provide enough pressure to meet fuel requirements as the available fuel injector on-time decreases with increasing engine speed.
