Control method for temporarily increasing the exhaust gas temperature

The invention relates to a control method for increasing the exhaust gas temperature of an internal combustion engine by increasing the exhaust back-pressure, yet maintaining an exhaust gas recirculation rate. Further, the fuel injection quantity of a main injection into the engine is increased. In...

Beschreibung
Zusammenfassung:	The invention relates to a control method for increasing the exhaust gas temperature of an internal combustion engine by increasing the exhaust back-pressure, yet maintaining an exhaust gas recirculation rate. Further, the fuel injection quantity of a main injection into the engine is increased. In this way, it is possible to increase the temperature of the exhaust gas and avoid engine oil dilution due to retarded post-injections.
