PURPOSE:To ensure a desired increase or decrease in the quantity of injected fuel, by effecting the multiplication of a fuel increasing coefficient and a signal indicating an effective basic fuel injection time removed of a deal time based on the delay of the operation of a solenoid, the play of an injection valve and so forth. CONSTITUTION:A basic fuel injection time signal Ti and a fuel increasing or decreasing coefficient signal alpha are applied to input terminals 1, 4. A dead time To is subtracted from the basic fuel injection time signal Ti by a subtracter 3, the output of which is multiplied by the coefficient signal alpha by a multiplier 5. The output of the multiplier 5 is applied to an adder 6 so that the basic fuel injection time signal Ti is added to the output of the multiplier. The output of the adder 6 is used as an actual fuel injection time signal to energize a solenoid. |
