ABSTRACT:
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, 2a), 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.
