What is the reason why a China V vehicle does not consume urea solution?

The reason why a China V vehicle does not consume urea solution is that the urea nozzle is clogged. It is necessary to check whether the urea nozzle is crystallized and blocked, and whether the control unit is not supplying power to control the nozzle. More information about automotive urea solution is as follows: 1. The scientific name of automotive urea solution is Diesel Exhaust Fluid (DEF). It is used in diesel engines and is a liquid applied in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. 2. Its composition consists of 32.5% high-purity urea and 67.5% deionized water. Although automotive urea is also urea, it is vastly different from agricultural urea. Automotive urea has strict ratio requirements, essentially composed of high-purity urea and deionized water, with the proportion strictly controlled. One of the standards for quality is the degree of impurity control. Agricultural urea contains more particles, metal ions, minerals, and other impurities, which are very harmful. Extended information: The China V Motor Vehicle Pollutant Emission Standard, also known as the 'China V Standard,' has an emission control level equivalent to the European Euro 5 emission standard currently in effect. From China I to China IV, each upgrade in the standard reduces single-vehicle pollution by 30% to 50%.
