ABSTRACT:
The invention is directed to an internal combustion engine such as an engine for a motor vehicle. The engine defines a combustion chamber wherein an air/fuel mixture is combusted during operation of the engine whereby an exhaust gas containing nitrogen oxides is generated. The engine has a catalytic converter for treating the exhaust gases including reducing the nitrogen oxides. The air/fuel mixture supplied to the combustion chamber is adjusted in such a manner that first an oxygen excess is present in the combustion chamber and then an oxygen deficiency is present. A control apparatus determines the mass (mNOx) of the nitrogen oxides flowing to the catalytic converter during oxygen excess and changes over from the oxygen excess to the oxygen deficiency when the mass (mNOx) reaches a pregiven inflow mass (mZ).
