Abstract

TITRE : Procédé et dispositif de gestion d’un filtre à particules d’un moteur à combustion interne Procédé de gestion d’un moteur à combustion interne (1) équipé d’un filtre à particules (2), selon lequel on détermine la charge du filtre (2) en particules de suie selon un modèle, et par la régénération on diminue la charge du filtre. On surveille la température du filtre à particules 2, et par la surveillance de la température on détecte s’il y a une régénération du filtre à particules (2), et si le modèle détermine que le filtre à particules (2) est vide et si en même temps la surveillance de la température détecte une régénération, on constate un défaut du modèle de charge et on adapte le fonctionnement du moteur. Figure 1TITLE: Method and device for managing a particle filter of an internal combustion engine Process for managing an internal combustion engine (1) equipped with a particle filter (2), according to which the load is determined of the soot particle filter (2) according to a model, and by regeneration the load on the filter is reduced. The temperature of the particulate filter 2 is monitored, and by monitoring the temperature it is detected whether there is a regeneration of the particulate filter (2), and whether the model determines that the particulate filter (2) is empty and if at the same time the temperature monitoring detects a regeneration, a fault in the load model is noted and the operation of the motor is adapted.
