Abstract
A method is described for operating an internal combustion engine (1) especially of a motor vehicle, wherein a lean air/fuel mixture is supplied to a combustion chamber (4) in a first mode of operation and a stoichiometric or a rich air/fuel mixture is supplied to the combustion chamber in a second mode of operation. This supplied air/fuel mixture is then ignited in the combustion chamber (4). The ignition time point or the ignition angle (ZW) for the ignition of the air/fuel mixture is shifted in the direction of retardation for a transition between the two modes of operation.
