What does China V mean for vehicles?
2 Answers
China V for vehicles refers to the China V emission standard, which is the abbreviation for the National Fifth Stage Emission Standard for Motor Vehicle Pollutants. It imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Compared to the China IV standard, the China V standard reduces nitrogen oxide emissions from standard light-duty vehicles by 25%, and requires carbon monoxide emissions from gasoline vehicles meeting the China V standard to be no more than 1000 milligrams per kilometer. Vehicle emission standards are established to implement environmental protection regulations, reduce and prevent pollution from vehicle exhaust, protect the ecological environment, and ensure human health. They are designed to control the emission of harmful gases from vehicle exhaust.
China's National V (China 5) is essentially the fifth-stage vehicle emission standard implemented in China, specifically designed to limit harmful pollutants emitted by new vehicles, such as nitrogen oxides and particulate matter. I understand that this standard was mandatorily enforced nationwide starting in 2017, imposing stricter requirements than the previous National IV, primarily aimed at reducing air pollution issues, including haze control. The practical impact is significant—for instance, automakers need to modify engines and exhaust systems, which may slightly increase costs, but it benefits the environment and public health in the long run. When purchasing a car, opting for a National V-compliant vehicle makes license plate registration easier in some major cities, whereas older National IV vehicles may face restrictions. In summary, National V represents a crucial step forward in environmental protection, driving us toward cleaner transportation methods.
