ABSTRACT:
A control device for an automotive engine provided with a fuel injection valve determines the current value of a parameter (e.g. the mean effective combustion pressure) indicative of the output power of the engine, and compares it to the target value thereof determined, for example, from the temporal change of the throttle opening degree. At least one of the parameters: the driving pulse width of the fuel injection valve (corresponding to the amount of fuel supply), the ignition timing, and the amount of intake air, is selected as a manipulated variable and controlled so as to reduce the difference between the current and target values of the parameter.
