ABSTRACT:
A safety arrangement is provided to protect an internal combustion engine from excessive temperatures in case of an abnormality in its circulating cooling system. In response to failure of an electrical coolant pump, the safety arrangement generates signals for retarding the ignition and/or reducing the fuel injection and/or limiting the charge so as to limit the load and/or the speed of the internal combustion engine.
