Abstract

Mélangeur de réducteur pour gaz d’échappement L’invention concerne un mélangeur (1) pour mélanger un gaz d’échappement et un réducteur, comprenant une boîte et un pulvérisateur de réducteur, le gaz d’échappement circulant dans la boîte depuis un orifice d’entrée (4) jusqu’à deux orifices de sortie (5) selon une circulation (C), le pulvérisateur pulvérisant le réducteur dans la circulation (C), la boîte comprenant une première chambre et une deuxième chambre, la première chambre s’étendant principalement selon un axe de pulvérisation (P) sensiblement parallèle à un plancher (7) et médiateur des deux orifices de sortie (5), étant fermée de manière étanche à l’exclusion de l’orifice d’entrée (4), d’un orifice de pulvérisation (6) et d’une fenêtre (10), la fenêtre (10) sortant de la première chambre (7) selon un axe de fenêtre (F) perpendiculaire au plancher (7), et la deuxième chambre (9) étant fermée de manière étanche à l’exclusion de la fenêtre (10) et des deux orifices de sortie (5).
