EXHAUST LINE WITH REAGENT INJECTOR

摘要

The invention relates to an exhaust line that comprises: a duct (3) including an injection segment (7) with an inner channel defined by a side wall, the exhaust gas flow including exhaust gas central streams in a central area of the inner channel (17) and exhaust gas peripheral streams in the vicinity of the side wall; a reagent injector (5) capable of injecting a reagent in an injection direction (F1). The duct (3) is conformed so that the exhaust gas central streams flow substantially parallel to the central line (L1) of the inner channel, the exhaust line (1) including a means (31) for imparting to at least some peripheral streams a rotary movement, through the inner channel, about a rotation axis that is slightly inclined relative to the injection direction (F1).
