Abstract

Dispositif de purification de gaz d’échappement , ligne d’échappement et véhicule associés Ce dispositif (16) de purification de gaz d’échappement, comprend : - un conduit (18), définissant un passage (26) de circulation de gaz d’échappement ; et - un injecteur (20) pour injecter un agent réducteur, l’injecteur (20) s’étendant dans le passage (26) de circulation et comprenant : - une buse d’injection (28) comprenant au moins un orifice d’injection (42) de l’agent réducteur gazeux ; et - une pluralité de couples de déflection (32), chaque couple de déflection (32) étant formé de deux déflecteurs (44) s’étendant chacun radialement entre la buse d’injection (28) et une extrémité radiale (46) et présentant chacun une hauteur radiale (H). Les déflecteurs (44) de chaque couple de déflection (32) présentent une hauteur radiale (H) différente de celle des déflecteurs des couples de déflection (32) qui lui sont adjacents. Figure pour l'abrégé : figure 1Exhaust gas purification device, associated exhaust line and vehicle This exhaust gas purification device (16) comprises: - a duct (18), defining a passage (26) for the circulation of gas. exhaust; and - an injector (20) for injecting a reducing agent, the injector (20) extending into the circulation passage (26) and comprising: - an injection nozzle (28) comprising at least one injection orifice (42) gaseous reducing agent; and - a plurality of deflection pairs (32), each deflection pair (32) being formed of two deflectors (44) each extending radially between the injection nozzle (28) and a radial end (46) and having each a radial height (H). The deflectors (44) of each deflection pair (32) have a radial height (H) different from that of the deflectors of the deflection pairs (32) which are adjacent to it. Figure for abstract: figure 1
