The reducing agent dosing system has a feed pump (1), particularly a pump unit, by which a reducing agent (2) is conveyed from a reducing agent tank over a conveying line and is introduced in an exhaust gas stream (4) of an internal combustion engine over a nozzle (3). The feed line is formed by a double-walled feed line (5), particularly a double-walled hose, where the reducing agent is conveyed through an inner line (6). The reducing agent is sprayed inside or outside the nozzle by compressed air. An independent claim is included for a method for operating a reducing agent dosing system. |
