ABSTRACT:
An apparatus and method for varying the duration of current levels of a fuel injection signal used in connection with an electronically controlled hydraulic actuator unit injector fuel system is disclosed. The apparatus and method varies the duration of the pull-in current of the fuel injection signal delivered to the unit injector based on sensed engine parameters, which preferably include a sensed temperature of the engine and engine speed.
