What is the vehicle emission standard in China?
2 Answers
The vehicle emission standards in China are China V and China VI. The relevant introduction to vehicle emission standards is as follows: Introduction to China V standard: The China V standard was implemented nationwide on January 1, 2018. It imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. Compared to the China IV standard, nitrogen oxide emissions must be reduced by 25%, and there are additional limits on non-methane hydrocarbons and PM emissions, which help reduce air pollution and prevent smog. How to check the vehicle emission standard: You can find the vehicle's emission standard by looking at the label on the back of the vehicle's environmental compliance sticker. The vehicle's certificate of conformity also contains a description of the emission standard on the first page, usually in the form of a string of characters. You can search online for the meaning of this string to determine the emission standard (China V, China VI, etc.).
Vehicle emission standards mainly refer to classifications like China 6, and I'll share some maintenance experience. Standards such as China 3, China 4, China 5, and China 6 require progressively lower pollutant emissions, with China 6 divided into Class A and B, where Class B is the strictest, controlling harmful particulates like PM2.5. To check your vehicle's standard, refer to the first page of the vehicle registration certificate or use the VIN on environmental websites. Older vehicles like China 2 emit more pollutants and may face traffic restrictions. High-standard vehicles use advanced catalytic converters to reduce nitrogen oxide emissions, saving money and being eco-friendly. It's recommended to regularly inspect the exhaust system to stay compliant and avoid costly repairs during annual inspections. High-emission vehicles might have higher insurance premiums, so upgrading early can save hassle. Keep an eye on the upcoming China 7 standards—small maintenance makes a big difference.
