ABSTRACT:
An internal combustion engine fuel injection control has two groups of injectors energized alternately by a pulse duration modulating control system, in accordance with a fuel demand signal. There is also a circuit controlled by V.sub.fd for changing the phase of the injection sequence when V.sub.fd is below a predetermined value to vary the timing of injection relative to the timing of engine valve actuation.
