ABSTRACT:
This invention discloses an engine rotation sensor which can generate angle- and timing-pulses from one sensor. The ratio of the intervals between these pulses generated by the rotation sensor is determined. The crank angle pulses and the timing pulses are discriminated depending on whether this ratio is less than or equal to a predetermined value, or not. The injection of fuel of each injector is controlled by a pulse which is discriminated as a timing pulse.
