Abstract:
The present invention relates to a method for adjusting a mass flow of an exhaust gas return of an internal combustion engine, taking into consideration a NOx behavior, wherein a controlling system provides a coupling of a virtual NOx determination with a real NOx control. Furthermore, an internal combustion engine with appropriate controlling means is proposed.
