Abstract
To provide for rapid interruption of the combustion process in an internal combustion engine, for example by inhibiting ignition or supply of fuel by a fuel injection system, speed pulses are integrated and the integrated signal evaluated with respect to a reference to determine whether the integrated signal, and hence the speed of the engine, exceeds a predetermined level; a timing circuit is connected to the evaluation circuit to provide a control signal for a predetermined time interval to inhibit fuel combustion of the engine for the predetermined time interval in case the speed is exceeded. If fuel injection pulses are to be inhibited, then the timing of the timing circuit is synchronized with the fuel injection pulses to provide for complete suppression thereof without pulse overlap.
