摘要： A medium supply system of an exhaust gas cleaning device for treating the exhaust gas of an internal combustion engine comprising a storage tank and a supply line which is connected to the storage tank for supplying the medium to a dosing unit connected to an exhaust pipe and to a recycling line for recycling the medium to the storage tank. The supply line and/or the recycling line are provided with at least one conduit area comprising at least one first and second parallel partial channels for the medium circulation, wherein said partial channels exhibit different insulation properties. An exhaust gas cleaning device comprising the inventive supply system and a method for the operation thereof are also disclosed.

摘要： The invention proposes a method for metering a reagent, in which the reagent is sprayed into a spray tube (12) via an electrically activated metering valve (24), and is mixed in the spray tube (12) with compressed air, and in which the reagent mixed with compressed air is introduced by means of the spray tube (12) into an exhaust gas duct (10) and is atomized, and a device for carrying out the method. The procedure according to the invention is distinguished in that the duration of the metering valve activation signal (34) is corrected depending on the differential pressure between the hydraulic pressure (p_Rea_hyd) of the reagent in the metering valve (24) and the pneumatic pressure (p_D_pneu) in the spray tube (12). The procedure according to the invention permits a high degree of accuracy in the metering of the reagent.
