Abstract:
The inventive system for evaluating the charged state of depollution means integrated into the exhaust line of a motor vehicle engine is characterised in that it comprises means (7) for determining a pressure in the depollution means, means (8) for determining the volume gas flowrate upstream said depollution means (10) and means for comparing the depollution means state defined by the thus determined pressure and the volume flowrate with a predetermined diagram (11) of the absent, overcharged and clogged states of the depollution means in order to evaluate the state thereof.
