ABSTRACT:
A fuel delivery system for internal combustion engines in which an electric-motor fuel pump supplies fuel under pressure to a fuel injector carried by the engine. An engine air intake manifold is likewise carried by the engine and supplied with combustion air. A pressure sensor is responsive to a pressure differential between the fuel injector and air manifold for controlling a pulse-width modulated drive signal applied to the fuel pump motor.
