How to Identify China VI Emission Standard?
3 Answers
The simplest method is to check the vehicle's environmental protection label, where the 'Emission Standard' section will indicate which China standard it meets. However, the environmental protection label has now been abolished, meaning current vehicles no longer carry this label. For new vehicles, you can check the vehicle's factory certificate or conformity certificate. You can also verify this by logging into the public inquiry platform of the Motor Vehicle Environmental Protection Website, where you'll need to enter the vehicle's VIN number and the last 6 digits of the engine number. Here is some related information: 1. Symbols for China 1 to China 6: The symbols from China 1 to China 6 are I, II, III, IV, V, and VI, respectively. The China 1 emission standard was first introduced on July 1, 2000. Since it was modeled after European emission standards to align with international norms, the symbols from China 1 to China 6 also use Roman numerals. New emission standards have been introduced every few years since then. 2. China VI has two phases: The 'China VI Standard' is divided into two phases: 'China VI a' and 'China VI b,' which were planned for nationwide implementation on July 1, 2020, and July 1, 2023, respectively. However, the China VI standard is extremely stringent, far surpassing the European Euro 6 emission standards and the U.S. Tier 3 standards, making it one of the strictest emission standards globally. The implementation period for the China VI standard is also longer.
Last time I went car shopping, I specifically researched the China 6 emission standards. Nowadays, new vehicles basically all meet the China 6b standard, which essentially means stricter exhaust pollution control. The most straightforward way is to check the Vehicle Conformity Certificate or the onboard environmental information list - these documents will clearly display 'China VI' labeling. Many models also have a blue oval environmental label in the engine compartment with 'CHINA VI' printed on it. If you want to see specific emission data, you can check the appendix of the user manual or scan the environmental QR code on the windshield with your phone. Nowadays, salespeople at 4S stores are quite knowledgeable - you can directly ask them 'Does this car meet China 6b standards?' and you'll definitely get an accurate answer.
Oh, I know this inside out! When our company fleet was being updated, I went through China VI materials every day. The key points are: the production date must be after July 2023 (China VIa was July 2020), the vehicle model must include the letter 'B', and check the models listed after the 417th batch of announcements from the MIIT. But recently, I discovered a trick: the exhaust pipes of China VI vehicles are exceptionally clean to the touch, unlike older vehicles that leave your hands black after a drive. A seasoned mechanic taught us to check the fuel—it must be labeled 'Suitable for China VI Vehicles'. Regular fuel can clog the particulate filter. The funniest part was when a colleague checked the wrong batch and mistakenly bought a China VIa vehicle instead of a VIb, almost failing the annual inspection.
