    摘要: A system is provided for admixing a reducing agent to an exhaust gas flow of an internal-combustion engine. The system includes an exhaust line and a metering device for feeding the reducing agent into the exhaust line, the metering device is arranged in or on a hollow body arranged on the exhaust line. An inner volume of the hollow body is connected in an exhaust-gas-conducting manner with the exhaust line. The reducing agent is feedable by a nozzle into the hollow body. A jacket body is provided between the hollow body and the nozzle-fed reducing agent, which jacket body surrounds the reducing agent at least in areas in the inner volume. Accordingly, a depositing of reducing agent on the metering device and on the hollow body is substantially avoided.
