| description | The invention relates to an exhaust aftertreatment device (7) for metering a liquid aftertreatment agent into an exhaust stream of an internal combustion engine, comprising a mixing chamber (22), in which the exhaust aftertreatment agent is mixed with the exhaust stream, a mixing chamber (22) having a circularly cylindrical mixing pipe (8), which has a funnel-shaped end section (9) widening the periphery toward a free end, having a funnel element (17) opening at least partly conically in the direction of the mixing pipe (8), which has a plurality of passage openings (18) in the lateral wall (19) of the funnel element, and wherein an injection valve (21) for the exhaust aftertreatment agent is arranged at the end of the funnel element (17) that faces away from the mixing tube (8), in orderto inject the exhaust aftertreatment agent into the funnel element (17). According to the invention, the funnel element (17) is located at least substantially within the end section (9), coaxially with respect to the end sect |
