Abstract:
A system for determining the level of sulphur poisoning of a depollution device integrated into the exhaust line of a motor vehicle engine involves controlling the operation thereof, switching the system between a lean storage mode and a rich storage mode, calculating the sulphur storage speed in the lean mode, calculating the sulphur elimination speed in the rich mode, calculating the quantity of sulphur stored in the depollution device during the operation of the engine and comparing the quantity of sulphur with threshold values for determining a poisoning level of the depollution device.
