ABSTRACT:
A disc having first and second sets of markers thereon is rotated in sychronism with the crankshaft of an engine so that pickups associated with the disc produce pulse trains of two and three pulses per revolution of the crankshaft respectively. A circuit responsive to either the speed or load of the engine selectively connects one of the pulse trains to a fuel injection control circuit to induce the fuel injector to inject in synchronism with the pulses of the selected pulse train. Alternatively the pulses outputted by the ignition system are frequency divided and fed to the fuel injection control circuit.
