Abstract

Procédé de surveillance du fonctionnement d'un filtre à particules diesel du conduit de gaz d'échappement selon lequel on détermine l'émission de noir de fumée en aval du filtre à l'aide d'un capteur de particules , on modélise l'émission prévisible de particules en aval d'un filtre à particules diesel limite à l'emplacement du capteur de particules, et on estime que le filtre est en ordre si l'émission de noir de fumée mesurée est inférieure à l'émission de noir de fumée modélisée et que le filtre est défectueux dans le cas contraire. On prend comme émission de noir de fumée modélisée, la concentration modélisée de particules à l'emplacement de montage du capteur.Method for monitoring the operation of a diesel particulate filter of the exhaust gas duct according to which the emission of carbon black downstream of the filter is determined using a particle sensor, the emission is modeled predictable particulate matter downstream of a diesel particulate filter limits the location of the particulate sensor, and the filter is deemed to be OK if the measured carbon black emission is less than the carbon black emission modeled and that the filter is defective otherwise. The modeled carbon black emission is taken as the modeled particle concentration at the sensor mounting location.
