PROCEDE ET DISPOSITIF D'EXECUTION DU PROCEDE POUR DETERMINER L'ETAT DE CHARGE D'UN COMPOSANT INSTALLE DANS LA ZONE DES GAZ D'ECHAPPEMENT D'UN MOTEUR A COMBUSTION INTERNE

摘要

The process involves increasing mass flow of an exhaust gas in an internal combustion engine. A pressure variation in the upstream of a particle filter (20) in the exhaust gas zone (18) is determined. The load state of the filter is determined from the pressure variation. A threshold value is provided for the load state of the filter. The filter is regenerated if the load exceeds the threshold value.
