Abstract
MÉLANGEUR ET SYSTÈME DE POST-TRAITEMENT D’ÉCHAPPEMENT POUR UN MOTEUR Le présent modèle d’utilité concerne un mélangeur et un système de post-traitement d’échappement pour un moteur. Le mélangeur comprend : une coque externe comprenant une extrémité d’entrée pour la réception d’un gaz d’échappement de moteur ; et une coque interne située à l’intérieur de la coque externe, la coque interne comprenant une chambre d’agent réducteur pour la réception d’un agent réducteur pulvérisé vers le mélangeur ; une paroi de chambre de la chambre d’agent réducteur comprenant une paroi poreuse, et un interstice entre la paroi poreuse et la coque externe définissant un passage d’échappement, de façon à ce qu’une partie de l’échappement du moteur entré dans le mélangeur à partir de la première extrémité d’entrée entre dans la chambre d’agent réducteur à travers la paroi poreuse et l’autre partie de celui-ci s’écoule à travers le passage d’échappement.
