Fuels that are used nowadays can have a different densities or different heating values. Even when filling the fuel tank ( 7 ) the quality of the fuel in the fuel tank ( 7 ) can change since different fuels are mixed. For example a low density or a low heating value can lead to reduced performance of the internal combustion engine ( 1 ). It is therefore proposed that a fuel-specific factor k be determined using a sensor ( 2, 2 a), with which the characteristic of the combustion chamber pressure and/or a lambda value is measured, and using an algorithm. In a further embodiment the operating parameters (injected quantity, start of injection, end of injection, injection pattern, exhaust gas recirculation rate, etc.) are corrected using the factor k.
