Abstract

A correction factor takes into account the possible change in the quality of the fuel fed to an internal combustion engine between shut-down and restarting of the internal combustion engine. The correction factor is applied to the basic injection time period in the internal combustion engine. The correction factor is weighted with a weighting factor that is selected as a function of the filling level of a fuel reservoir container holding the fuel when the internal combustion engine is shut down, and of the filling level when the internal combustion engine is restarted.
