Abstract

Procédé de régénération d'un filtre a particules, le filtre à particules comportant au moins une cavité dotée de parois filtrantes, le procédé comprenant au moins une première catégorie de régénération dans laquelle la température des parois filtrantes est augmentée pour qu'elle soit comprise dans une première plage de températures de régénération assurant ainsi la combustion de suies contenues du filtre à particules. Après la mise en œuvre de la première catégorie de régénération : a) on génère une valeur représentative du colmatage du filtre à particules par des résidus non détruits durant la première catégorie de régénération ; b) puis, si cette valeur générée passe une valeur de seuil prédéterminée (Pl) , alors on déclenche volontairement une seconde catégorie de régénération du filtre à particules dans laquelle la température des parois filtrantes comprise dans une seconde plage de températures supérieure à la première.
