ABSTRACT:
A fuel injection control system and technique for an internal combustion engine is disclosed having at least one controlled offset fuel injector valve and only one controlled trim injector valve. The offset injector valves produce a constant quantity of fuel by being energized for a fixed pulse duration each injection cycle while the difference between that constant quantity and a desired fuel injection quantity calculated from a fuel schedule is supplied by the variable trim injector. The fuel supply schedule is determined by the engine variables of the operating system by an electronic fuel scheduler circuit which further supplies fuel injection timing pulses for triggering the beginning of the injection cycle. An alternate embodiment discloses using an electromechanical distributer to select which of the offset fuel injectors are energized during an injection cycle and a third embodiment illustrates the use of the fixed pulse width associated with the offset injectors to enable the selection process of the electromechanical distributor.
