Abstract

Procédé de nettoyage des gaz d'échappement d'un moteur thermique (10) en transformant les oxydes d'azote des gaz d'échappement par le dosage impulsionnel d'hydrocarbures dans le canal des gaz d'échappement (13) en amont du catalyseur des oxydes d'azote (16). On détermine la concentration en hydrocarbures des gaz d'échappement à l'aide d'un capteur (17) dans la veine des gaz d'échappement en aval du catalyseur (16), et on influence la quantité dosée d'hydrocarbures à l'aide de la concentration en hydrocarbures par le capteur d'hydrocarbures (17) ayant traversé le catalyseur d'oxydes d'azote (16) de façon à éviter juste le passage d'hydrocarbures à travers le catalyseur d'oxydes d'azote (16).
