Abstract

L'invention porte sur un procédé de régénération d'un filtre à particules (FAP) et d'élimination de soufre d'un catalyseur d'oxydation (DOC) accumulateur d'oxydes d'azote, le filtre à particules (FAP) et le catalyseur d'oxydation (DOC) accumulateur d'oxydes d'azote étant logés à l'intérieur d'une ligne d'échappement (4) dont est pourvu un moteur à combustion interne (1) d'un véhicule automobile à l'intérieur duquel est introduit un mélange air/carburant (M). Le procédé comprend une première étape d'enrichissement qui est réalisée lorsqu'une phase de régénération du filtre à particules (FAP) est déclenchée au cours de laquelle une richesse (R) du mélange air/carburant (M) augmente d'une première richesse (R1) à une deuxième richesse (R2) strictement supérieure à la première richesse. Le procédé comprend une deuxième étape d'enrichissement au cours de laquelle la richesse (R) du mélange air/carburant (M) augmente de la deuxième richesse (R2) à une troisième richesse (R3) strictement supérieure à la deuxième richesse (R2) qui est réalisée lorsqu'une instruction d'élimination de soufre du catalyseur d'oxydation (DOC) accumulateur d'oxydes d'azote est adressée par un superviseur de désulfatation, et lorsque une phase d'accélération (Phacc) du véhicule automobile est réalisée.
