Abstract
PURPOSE: To obtain stability and quick responsiveness in the whole rotary range of an engine by changing a proportional gain of PID compensation circuit as a function of engine rotational speed in an electronic fuel injection device which regulates amount of fuel injection.
CONSTITUTION: As a result of comparison, by means of a comparator 22, between sawtooth wave output eT from a sawtooth wave generation circuit 21 and an engine rotational speed signal en aftter its going through an integration circuit 23 for smoothing, signal Pc is outputted during period where eT<en is satisified. The signal Pc and a rotational speed deviation value Δe are added to AND circuit 24, then amplitude of the signal Pc is made a value of a signal Δe, subsequently the output is supplied to an integration circuit 25 through a transistor Tr3, thus an output eo is obtained as a result of multiplicative operation for smoothing. The output eo is obtained through pulse width moduation of rotational speed signal en, and amplitude modulation by rotational speed deviation signal Δe, is a ratational speed control signal suitable for fuel injection peculiarity in this rotational speed.
