Exhaust line injection and mixing device

Abstract

Exhaust line injection and mixing device The injection and mixing device comprises: - a casing (13) having an exhaust gas inlet (15) and an exhaust gas outlet (17), the casing (13) internally delimiting a passage (19) for the exhaust gases from the exhaust gas inlet (15) to the exhaust gas outlet (17), the exhaust gas inlet (15) opening into an inlet zone (45) of the passage (19); - an injector (21) of a liquid comprising a nitrogen oxide reducer or a precursor of such a reducer; - a deflector (39) housed inside the casing (13) and defining in the passage (19) a first passage (41) connecting the inlet zone (45) to the exhaust gas outlet (17), in which the exhaust gases flow at a first average velocity, and a second passage (43) connecting the inlet zone (45) to the exhaust gas outlet (17), in which the exhaust gases flow at a second average velocity lower than the first average velocity, the injector (21) injecting the liquid into the second passage (43).
