Can a China 5 vehicle continue to drive after running out of urea?

[CarlosDella]

A China 5 vehicle cannot be driven after running out of urea. The function of urea solution is to chemically react with nitrogen oxides in vehicle exhaust to produce non-toxic nitrogen and water, thereby reducing the emission of toxic gases in vehicle exhaust and minimizing pollution. The SCR solution has significant advantages in the China IV diesel vehicle exhaust emission treatment system, and vehicle urea is an essential additive for the SCR solution. Precautions: 1. Regularly check the urea level in the urea tank and replenish urea solution in time. The consumption of vehicle urea solution is 4%-6% of diesel consumption. Estimate the amount of urea solution needed based on the trip and carry sufficient barrel urea solution if necessary. 2. When refilling vehicle urea solution, use a dedicated urea solution filling pipe to prevent impurities from mixing in. 3. Vehicle urea solution is alkaline and slightly corrosive. Avoid contact with metals (except stainless steel), as these materials react with trace amounts of ammonia in the urea solution to form compounds that affect SCR operation.
