泵送:由于根据车型系列使用2个罐来存储尿素与水的混合物(AdBlue~),因此需要进行泵送。将尿素与水的混合物(AdBlue~.)从被动罐输送至主动罐称为泵送。泵送期间,传输泵将尿素与水的混合物(AdBlue~)从被动罐泵入加注管路内。由于被动罐内的加注管路与主动罐加注管路彼此分开,因此尿素与水的混合物(AdBlue~)不会返回被动罐而是流入主动罐内。组件的安装
Pumping: Pumping is required because two tanks are used to store the urea-water mixture (AdBlue ~ ) depending on the model series. The transfer of the urea-water mixture (AdBlue ~ .) From the passive tank to the active tank is called pumping. During pumping, the transfer pump pumps a mixture of urea and water (AdBlue ~ ) from the passive tank into the fill line. Due to the separation of the fill line and the active tank fill line in the passive tank, the mixture of urea and water (AdBlue ~ ) does not return to the passive tank but instead flows into the active tank.
