DOSING SYSTEM FOR DOSING A REDUCING AGENT FOR EXHAUST GAS AFTERTREATMENT

摘要

The invention relates to a device for dosing a reducing agent, especially urea or a urea-water solution, for reducing the nitrogen oxides contained in the exhaust gas of an internal combustion engine. The invention also relates to a transport device (10) for transporting a reducing agent. Said transport device (10) is arranged in such a way that it can be fixed to or inside the reservoir (12). The transport device (10) forms a module which is separate from an apportioning device (32;52) containing a proportioning valve. Said apportioning device can be connected to the transport device (10) by means of a reducing agent line (38).
