Abstract
A fuel injection system which employs electromagnetic injection valves controlled by injection control pulses of variable width. When the engine is being operated in the overrunning condition, with closed throttle and elevated rpm, the normally provided fuel injection control pulses can be supplanted by substitute pulses of either constant or variable width. The apparatus includes a comparator circuit which determines whether the original control pulse is to be used or the substitute pulse. Several embodiments are presented.
