    摘要: The invention relates to a system for determining the level of sulphur poisoning of depollution means integrated into the exhaust line of a motor vehicle engine, said system being associated with means for controlling the operation thereof, for switching the system between a lean storage mode and a rich storage mode. The inventive system is characterised in that it comprises means (19) for calculating the sulphur storage speed in the lean mode, means (20) for calculating the sulphur elimination speed in the rich mode, means (21, 22) for calculating the quantity of sulphur stored in the depollution means during the operation of the engine and means for comparing (23) the quantity of sulphur with threshold values for determining a poisoning level of the depollution means.
