Abstract: The present invention refers to a method for operating an internal combustion engine in a transition operating mode, comprising the steps of determining an initial fuel oxidizer ratio threshold and a demanded fuel oxidizer ratio for a fuel mixture to be supplied to a combustion chamber of the engine, if the demanded fuel oxidizer ratio exceeds the initial fuel oxidizer ratio threshold, the engine is temporally operated in a raised response mode, in which a fuel oxidizer ratio threshold is increased from the initial fuel oxidizer ratio threshold to a raised fuel oxidizer ratio threshold, and a fuel mixture having the demanded fuel oxidizer ratio is supplied into the combustion chamber of the engine.
