Zusammenfassung: | The invention relates to a mixing device (7) for introducing a liquid (9) into an exhaust gas stream, having an exhaust gas line section (11), set up for conducting exhaust gas along the exhaust gas line section (11), and having a metering device (13), arranged and set up for introducing a liquid (9) into the exhaust gas line section (11). Here, at least one sound source (15) is provided which is arranged relative to the exhaust gas line section (11) and the metering device (13) in such a way that thorough mixing of the liquid (9) which is introduced into the exhaust gas line section (11) by means of the metering device (13) with the exhaust gas which flows in the exhaust gas line section (11) is promoted by way of sound which is emitted by the at least one sound source (15) when the at least one sound source (15) emits sound. |
