Patent ID: 8068970

Claim:
Control unit for an internal combustion engine, characterised in that output power can be controlled by means of a controlling parameter (T), in which an engine characteristic curve ( 11 , 12 ) which, at a value of the controlling parameter (T) which corresponds to a maximum output power, defines the output power (P) as a function of the engine's speed of revolution (ω), has an ascending part ( 12 ) at low speeds of revolution and a descending part ( 11 ) at high speeds of revolution, characterised in that if, when the engine ( 1 ) is operating, the speed of revolution exceeds a first upper limiting value (ω max,0 ) at the value of the controlling parameter which corresponds to the maximum output power, a first value (T 1 (ω)) of the controlling parameter (T) is set which corresponds to a reduced output power.
