What does China National V mean for vehicles?

[DeCamilla]

China National V refers to the fifth stage of the national motor vehicle pollutant emission standards, abbreviated as "National V Standard". Its emission control level is equivalent to the fifth stage emission standard currently implemented in Europe. Vehicle emission standards regulate the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). To curb the generation of these harmful gases and encourage automobile manufacturers to improve their products to reduce these emissions at the source, both Europe and the United States have established relevant vehicle emission standards. Among them, the European standards are the reference for China's vehicle emission standards.
