Abstract

L'invention porte sur un procédé de régénération d'un filtre à particules dans une ligne d'échappement de moteur à combustion interne de véhicule automobile par combustion des suies retenues à l'intérieur du filtre à particules, la régénération se faisant par des post-injections de carburant dans la ligne d'échappement, le carburant post-injecté étant brûlé dans la ligne d'échappement en produisant une montée de température dans la ligne. Pendant la régénération, il est effectué une succession d'intervalles de post-injections de carburant entrecoupés d'intervalles de suspension de post-injections de carburant pour une augmentation du taux d'oxygène (% O2 am FAP) dans la ligne d'échappement au moins au niveau du filtre à particules. Application dans le domaine des véhicules automobiles.
