Automotive urea must use the electronics industry class one ultra-pure water. Because the SCR catalyst carrier is prone to metal ion poisoning and thus lose the catalytic effect, the automotive urea solution must use the electronic industry's first class ultra-pure water (resistivity ≥18MΩ? cm). The urea solution for vehicles will begin to freeze at -11 ° C, and will freeze completely at -20 ° C in actual use. At present, the technology is to reduce the freezing point of the solution by adding modifiers, and to prevent the solution from solidifying.
