Abstract

A method for operating an internal combustion engine is described. At least one composition of a gas mixture is determined in at least one combustion chamber of the internal combustion engine. At least one combustion chamber pressure is detected in the interior of the combustion chamber and at least one local combustion chamber temperature is detected in the interior of the combustion chamber. The composition is inferred from the combustion chamber pressure and the combustion chamber temperature.
