Abstract
A returnless fuel delivery control system is disclosed which regulates fuel rail pressure at the level needed for precise control of fuel mass flow to fuel injectors at both normal and elevated engine temperatures. This regulation is accomplished by precisely controlling the speed of the fuel pump motor as a function of the projected fuel demand based on engine RPM and injector pulse width. The projection is modified as a function of differential pressure error. The differential pressure error responds to a fuel temperature strategy which increases the target differential pressure as a function of fuel temperature.
