Zusammenfassung:The invention provides an injection device (5) for a vehicle exhaust line and a corresponding exhaust line (1). The injection device (5) comprises: an injection chamber (7) having an injection zone (11) in which an exhaust stream flows in a direction of flow (F1); an injector (9) oriented to inject a jet of liquid (J) into the injection zone (11) in an injection direction forming with the flow direction (F1) an angle of between 270 degrees and 360 degrees ; a first impactor (25) having a first impact surface (29) arranged to directly intercept at least 30% of the liquid jet (J); at least one second impactor (27) having a second impact surface (37), having a zone (39) located under the edge of the first impact surface (29) in the direction of flow (F1), so that the liquid entrained along the first impact surface (29) by the exhaust gas flow falls on the second impact surface (37).
