Abstract
Device for limiting the exhaust gas temperature in an internal combustion engine consisting of a thermoelement (2) protruding into the engine exhaust manifold (1) and an electronic control unit (3) connected thereto, which is disposed to send an output signal dependent on the exhaust gas temperature sensed by the thermoelement to the fuel injection system (4) of the engine. When the output signal indicates that the temperature exceeds a maximum-permissible level, an excess of fuel is injected for cooling.
