    摘要: The invention concerns a procedure to determine the sulfur removal of a NOx storage catalytic converter in an exhaust gas aftertreatment system of an internal combustion engine, whereby conditions, in which a surplus of the reducing agent is generated in the internal combustion engine, are adjusted in the internal combustion engine for the sulfur removal, whereby a SOx removal amount is determined in a SOx removal calculation using a model from the reducing agent flow and from additional operating parameters of the internal combustion engine. In so doing, dynamic effects during the desulferization of the NOx storage catalytic converter can be better taken into account for the SOx removal calculation; and in so doing, the subsequent effect of the NOx storage catalytic converter on the reduction of the nitrogen oxides in the exhaust gas can be more accurately predicted, which makes the process management more streamlined and consequently more fuel efficient.
