Master Deng said that because of the understanding of Kelansu, there are no other brands used, and the urea produced by Kelansu is well-known among the owners, so it is safe and comfortable to use. Figure 1 shows the filter element after using tens of thousands of kilometers of inferior urea, followed by the filter element after using 300,000 km of kelan, which is good or bad. Through the above comparison, we can see that the SCR system filter element using kelan urea is clean and has no crystal structure; however, the filter element using inferior urea is full of crystal and dirt, and the inferior urea is used for the car urea pump and urea nozzle. The harm of the urea metering pump is very large, which may cause damage to the local or even the entire SCR system. Once damaged, the maintenance cost is very high. At present, the concept of environmental protection has been deeply rooted in the hearts of the people. Inferior urea still exists in the market, causing great damage to the environment and the interests of drivers. In this small series, the majority of car owners are reminded to use high-quality urea, please use kelan.
