Abstract

Procédé pour déterminer la capacité d'accumulation d'oxygène d'une installation de nettoyage des gaz d'échappement (23) comportant une sonde de gaz d'échappement (13) à caractéristiques discontinues montée en amont de l'installation de nettoyage des gaz d'échappement (23).Dans une durée précédant la détermination de la capacité d'accumulation d'oxygène, on fait la moyenne de l'action de régulation de la sonde de gaz d'échappement (13) et on tient compte de cette valeur moyenne pendant la détermination de la capacité d'accumulation d'oxygène de l'installation de nettoyage des gaz d'échappement (23) pour le calcul du dosage de carburant ou on utilise cette valeur moyenne pour corriger le coefficient lambda utilisé pour calculer la quantité d'oxygène accumulée.
