Method for regulating a combustion engine and electronic fuel injection apparatus using this method

Abstract

Abstract A method for regulating a combustion engine in which, as a function of operating parameter signals such as the number of revolutions, the accelerator pedal position, the engine temperature etc., an output signal is calculated in a computer (1) and this is used to control an electromechanical control element (3) for the injection quantity, a servo circuit (3 - 4 - 5) being provided for the control element, to which circuit the calculated output signal is fed as a control variable and the feedback signal from a response synchro (4) connected to the control element is fed as the regulating variable, the feedback signal being analysed for response synchro faults and if a fault is detected the servo circuit being opened. In order to permit emergency operation at least largely corresponding to normal operation in the event of malfunctions of the response synchro or the servo circuit, it is proposed that if a fault is detected the control variable determined in the computer circuit (1) be converted into an actuating signal for the control element, allowance being made for the operating characteristic of the control element (3). <IMAGE>
