Abstract (en)
[origin: WO2015153350A1] An apparatus for supplying Diesel Exhaust Fluid to an engine exhaust gas treatment system includes a reservoir to collect trapped air if the dosing module is clogged with crystalized urea. The reservoir is placed at the dosing valve inlet on a T-connection. The reservoir provides a closed chamber to receive trapped air in the DEF supply line, allowing DEF to flow to the dosing module. When DEF contacts the crystallized urea causing the clog, the urea dissolves, freeing the injector so that normal action of the dosing module is restored.
