Abstract

L'invention concerne des systèmes d'échappement d'un moteur diesel comportant une ligne d'échappement (4), dans laquelle est agencé un filtre à particules (9) nettoyé dans une phase de régénération par une élévation de la température des gaz d'échappement, ainsi que des procédés de commande d'un système d'échappement de ce type, dans lequel est agencé un élément de détection permettant de déterminer la charge en suie du flux de gaz d'échappement en fonction de laquelle une régénération du filtre à particules (9) est effectuée. Dans le cadre de ces systèmes et procédés déjà connus, des moyens de mesure supplémentaires sont requis jusqu'à présent pour initier la régénération. L'invention vise éliminer lesdits moyens de mesure supplémentaires. A cet effet, l'invention consiste à mémoriser dans l'unité de commande (25) un diagramme caractéristique, au moyen duquel peut être déterminée la charge en suie du filtre à particules (9) en fonction de la charge en suie du capteur de débit massique de gaz d'échappement (24, 34) et du débit massique de gaz d'échappement. L'élément de détection utilisé est un capteur de débit massique de gaz d'échappement (24, 34) qui est commuté dans le cas d'une charge en suie trop élevée dans un mode de nettoyage. On déduit de la charge en suie du capteur de débit massique de gaz d'échappement (24, 34) la charge en suie du filtre à particules (9), qui permet de déterminer le moment de l'exécution de la régénération du filtre à particules (9).
