Abstract

An internal combustion engine, especially for a motor vehicle, is described, which is provided with a storage catalytic converter which can be loaded with and unloaded of nitrogen oxides. Several states of deterioration (points 13) of the storage catalytic converter can be determined by the control apparatus. A sulphur content of the fuel used can be determined by the control apparatus from sequential states of deterioration (points 13).
