ABSTRACT:
A method is disclosed for varying the rate of injection of fuel during a single injection of fuel into a cylinder of an internal combustion engine. The method includes the steps of supplying pressurized fuel to the fuel inlet of an electrically controlled fuel injector and switching the fuel injector alternately on and off at a predetermined rate to thereby control the average rate of discharge of fuel from the fuel injector. The fuel injector can be a solenoid operated injector in which case the rate of discharge of fuel from the fuel injector can be controlled by modulating the width and frequency of pulses used to switch the fuel injector on and off.
