摘要

The line (10) has an intermediate space (20) between an outer wall (16) and an inner wall (18) of a double-walled region (14) designed flow throughable by a medium. A supply unit is provided for supplying heat quantity from the exhaust gas of an internal combustion engine, into the intermediate space. An initiating unit is provided for initiating a partial flow of the exhaust gas of the internal combustion engine into the intermediate space. An outlet port (32) is arranged downstream to the initiating unit.
