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.
Claims7
A method for controlling an internal combustion engine, which comprises:
- determining a basic injection time period in dependence on operating parameters of the internal combustion engine;
- correcting the basic injection time period with a correction factor taking into account a possible change in a quality of fuel fed to the internal combustion engine between a shutting down and a restarting of the internal combustion engine;
- weighting the correction factor with a weighting factor;
- and
- selecting the weighting factor in dependence on a filling level of a fuel reservoir container holding the fuel when the internal combustion engine is shut down, and on the filling level when the internal combustion engine is restarted.
