ABSTRACT:
An electronic fuel injection control includes a main control circuit which controls fuel flow to the engine by controlling the duration of pulses applied to fuel valves. In addition there is a transient fuel varying control including a differentiating circuit which differentiates the signal from a throttle position transducer. This differentiator controls a variable frequency clock which forms part of the main fuel control so that the pulse duration is lengthened or shortened for a given value of the engine parameter which controls the main fuel control according to the rate of increase or decrease of the throttle position signal.
