Abstract

The invention is directed to a method for limiting the temperature of the exhaust gas of an internal combustion engine operating at high load. In the method, a first measure for reducing the exhaust-gas temperature is carried out when the engine is operating under high load. Then, a check is made as to whether this measure is effective. If the first measure is inadequately effective, then a second measure is carried out to reduce the exhaust-gas temperature.
