Abstract

Le procédé est mis en œuvre pendant une chauffe d’un système de dépollution des gaz d’échappement d’un moteur thermique à essence, la chauffe étant obtenue à partir d’une dégradation de l’avance à l’allumage du moteur thermique, le moteur thermique faisant l’objet d’une surveillance (M2) incluant un comptage (NR) des instabilités de combustion et une première comparaison (B3) du comptage à un premier seuil de nombre d’instabilités de combustion (TH1), et un dépassement du premier seuil par le comptage déclenchant un premier signalement d’anomalie (ODB1, MIL). Conformément à l’invention, le procédé comprend une deuxième comparaison (B5) du comptage d’instabilités de combustion à un deuxième seuil de nombre d’instabilités de combustion (TH2), le deuxième seuil étant inférieur au deuxième seuil, et une réduction (RGA) de la dégradation de l’avance à l’allumage du moteur thermique lorsque le comptage atteint le deuxième seuil.
