ABSTRACT:
An engine controlling device includes an operating circuit (3) supplied with output signal of a knocking sensor (1) to generate a control signal which is used to effect an optimum control of at least one of ignition timing, exhaust gas recirculation flow rate, fuel injection quantity and fuel injection timing, to optimize combustion state of the engine. The device is further provided with an acceleration detector (5) whose output signal is supplied to the operating circuit (3) to generate a forced control signal during the accelerating condition of the engine regardless of the control signal derived from the knocking sensor (1). The forced control signal is used to control at least one of the above-mentioned control variables, and eliminates adverse influence of delay time in the control device to enable optimization of the combustion state even during a sudden acceleration.
