Abstract (en)
[origin: EP2687286A2] The mixing device (1) has an inner tube (7) with a premixing area (10) formed inside the inner tube, which is arranged inside a housing (4) and is extended parallel to a main injection device (5) of a metering device (6) for feeding a liquid or a liquid-gas mixture. A main exhaust gas stream (12) is guided between the housing and the outer lateral surface (14) of the inner tube. The partial exhaust gas stream (17) flows through the premixing area in the main mixing area (16). The main exhaust gas stream comprises a larger exhaust gas volume proportion than the partial exhaust gas stream.
