Abstract

L’invention concerne un procédé de diagnostic de l'absence d'un filtre à particules (4) dans une ligne d'échappement (2) d'un moteur (1) à combustion interne, ladite ligne d'échappement (2) étant équipée d'un filtre à particules équipé d'un capteur (6) de pression différentielle connecté en amont et en aval du filtre à particules (4), caractérisé en ce que le procédé comprend une étape de calcul du gradient de débit volumique de gaz d’échappement traversant le filtre à particules (4), une étape de comparaison de ce gradient à un gradient minimum de pression différentielle et une étape dans laquelle on diagnostique que le filtre à particules (4) est soit présent si le gradient de pression différentielle est supérieur au gradient minimum de pression différentielle, soit absent si le gradient de pression différentielle est inférieur au gradient minimum de pression différentielle. Figure 1The invention relates to a method for diagnosing the absence of a particulate filter (4) in an exhaust line (2) of an internal combustion engine (1), said exhaust line (2) being equipped with a particulate filter equipped with a differential pressure sensor (6) connected upstream and downstream of the particulate filter (4), characterized in that the method comprises a step of calculating the volume flow rate gradient of gas exhaust passing through the particulate filter (4), a step of comparing this gradient with a minimum differential pressure gradient and a step in which it is diagnosed that the particulate filter (4) is either present if the differential pressure gradient is greater than the minimum differential pressure gradient, or absent if the differential pressure gradient is less than the minimum differential pressure gradient.
