Abstract

L'invention concerne un système de traitement postcombustion de gaz d'échappement de moteur comprenant un coude acheminant un écoulement de gaz d'échappement dans une direction courbe vers une partie rectiligne. Un gicleur est monté dans le coude pour introduire une pulvérisation d'un fluide ayant un axe de symétrie dans l'écoulement de gaz d'échappement. L'axe de symétrie croise l'écoulement de gaz d'échappement avançant dans la direction courbe au niveau d'un angle de croisement inférieur à 50 degrés.
