How to Distinguish the National Emission Standard of a Car?
2 Answers
Here is a detailed introduction to the methods for checking a car's emission standard: 1. Check the relevant content on the compliance certificate: The vehicle compliance certificate contains many key pieces of information, including the emission standard, which will clearly indicate the national emission standard the vehicle complies with. 2. Review the environmental information list provided with the vehicle: When purchasing a car through official channels, the accompanying documents will include an environmental information list. The first section related to vehicle information will have an item for the emission stage, which will indicate whether the model is National V or National VI. 3. Query through specialized websites: After identifying the model you intend to purchase, you can find specific vehicle identification numbers in its related documents, such as the engine number and chassis number. By entering these numbers on the official vehicle environmental protection website, you can access the relevant environmental information of the vehicle, including the emission standard it complies with.
China VI vehicles have thicker exhaust pipes and multiple sets of engine sensors. Check the emissions chapter in the manual or visit the manufacturer's official website to view the configuration table. Light-duty vehicles manufactured after 2019 must comply with China VI standards, while heavy-duty vehicles have been granted an extension. Here's a handy trick: look at the OBD interface - China VI uses a 16-pin connector with a locking mechanism, whereas China V uses an 8-pin. Vehicles that take 92-octane fuel adhere to older standards; China VI recommends 95-octane fuel to meet environmental targets.
