Why is a China V vehicle not consuming urea?

[McSkylar]

Check if the urea nozzle is crystallized. More information about China V vehicles not consuming urea is as follows: 1. Introduction: The scientific name of automotive urea is Diesel Exhaust Fluid (DEF). It is used in diesel engines and is a liquid applied in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition is 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, basically consisting 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 impurities such as particulates, metal ions, and minerals, which are very harmful. 2. Check the urea nozzle: This involves checking whether the urea nozzle is crystallized, causing blockage, and whether the control unit is not supplying power to the nozzle.
