Abstract

A control device for an internal combustion engine comprising a knocking detecting means and an operating and controlling means which generates a feedback control signal in response to a knocking detection signal from the knocking detecting means and which feedback controls ignition timing, etc. so as to maintain the firing condition of the engine in optimum condition. The control device further comprises an acceleration detector, the output signal of which controls the knocking detecting means or the operating and controlling means in such a manner that said feedback control signal is amplified to a greater extent in the accelerating condition than in the normal condition, as a result of which the ignition timing, etc. is feedback controlled more quickly in the accelerating condition than in the normal condition, so that the firing condition is maintained in optimum condition even in the accelerating condition.
