Method for operating an internal combustion engine

A mixture pilot control for operating an internal combustion engine, in particular a gasoline engine of a motor vehicle, is provided. The mixture pilot control determines at least one composition of an air-fuel mixture required for a predetermined target air-fuel mixture ratio. The internal combusti...

Beschreibung
Zusammenfassung:	A mixture pilot control for operating an internal combustion engine, in particular a gasoline engine of a motor vehicle, is provided. The mixture pilot control determines at least one composition of an air-fuel mixture required for a predetermined target air-fuel mixture ratio. The internal combustion engine is also provided with a lambda control with at least one lambda probe arranged in the exhaust gas flow of the internal combustion engine for determining a deviation of the actual air-fuel ratio from the predetermined target air-fuel ratio. Operating-parameter-dependent correction factors for the composition of the air-fuel mixture by the mixture pilot control are determined in dependence on the lambda control deviation, at least one of the load and/or the rotational speed and/or the temperature of the internal combustion engine, and further operating parameters of the vehicle other than the load, rotation speed or temperature of the internal combustion engine.
