Abstract

Le procédé de pilotage d'un moteur à combustion interne à allumage commandé (1), comportant un dispositif d'allumage (101) pilotant une avance à l'allumage, un dispositif d'injection pilotant une richesse, des cylindres (3) reliés à une ligne d'échappement (4) comprenant un filtre à particule (6), comprend, suite à une demande de régénération du filtre à particules, les étapes consistant à : a. donner une autorisation de régénération ; b. estimer ou évaluer une température des gaz d'échappement au niveau du filtre à particules ; c. modifier, en fonction d'une valeur estimée de la température des gaz d'échappement au niveau du filtre à particules : i. une avance à l'allumage de sorte à augmenter la température des gaz à l'échappement ; et/ou ii. une richesse de sorte à apporter de l'oxygène à l'échappement.
