Abstract

The invention is directed to a safety arrangement for an internal combustion engine with self-ignition such as a diesel engine or the like wherein the operational signals of throttle position, rack travel and rotational speed are continuously monitored and compared with upper and lower limit values for these signals. From this comparison, comparison signals are generated and are combined with each other to provide an overall monitoring of the operation of the diesel engine so that the latter can be shut off when impermissible ranges of operation are present or, if conditions permit, the engine can be switched to an emergency mode of operation so that the motor vehicle may be driven to the next service station for repair.
