| 摘要 |
The invention relates to a reducing agent metering system for injecting a reducing agent into the exhaust gas stream of a combustion engine for selective catalytic reduction, with a feed pump, by means of which reducing agent is conveyed from a reducing agent tank via a delivery line and is introduced via at least one nozzle into the exhaust gas stream of the combustion engine, whereby the delivery line is formed by a hose (1) that has on the outside an electrical conductor (2) that encloses the hose (1) like a jacket, whereby the reducing agent metering system has a monitoring unit by means of which the electrical conductivity between the reducing agent in the hose (1) and the electrical conductor (2) is monitored. |
