ABSTRACT:
In a method for changing the operating mode in an internal combustion engine it is possible to switch between an operating mode with spark ignition of the engine and an operating mode with auto-ignition of the engine. Hereby, a first map is provided in which at least one range is specified in which a suitable auto-ignition of the engine can take place. After the engine start, therefore, it is determined whether the engine has reached an operating point lying within this range of the first map in order then to switch the engine to the operating mode in which auto-ignition can take place reliably.
