Abstract: This exhaust gas purification device (2, 102), comprising an upstream pipe (4), in which a first exhaust gas purification member (6) is housed, a downstream pipe (8) in which a second exhaust gas purification member (10) is housed, a mixing chamber (12) and an injection device (20) for a nitrogen oxide reducing product;is characterized in that the mixing chamber includes a first deflector member capable of channeling the flow of exhaust gas such that it flows through the jet of nitrogen oxide reducing product substantially perpendicular to the second deflector member (36, 56), the second deflector member being configured to form two swirling flows of a mixture of exhaust gas and nitrogen oxide reducing product;and in that the device further includes an element (54, 58) for protecting the second member (10) for purifying exhaust gas.
