How is China 6 labeled?
3 Answers
China 6 is labeled as VI. China 6 is currently the strictest automobile emission standard, which is formulated to implement the Environmental Protection Law of the People's Republic of China and the Air Pollution Prevention and Control Law of the People's Republic of China, prevent and control the environmental pollution caused by the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. Automobile emission standards refer to the regulations on the content of harmful gases such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), PM (particulate matter), soot, etc., emitted from automobile exhaust. With the increasing severity of automobile exhaust pollution, the country has promoted the advancement of automobile emission control technologies through strict regulations.
When buying a car, I often check the "China 6" label, which is clearly marked as "China VI" or "China VI" on the vehicle's nameplate, especially near the engine compartment door or below the door frame on the passenger side. For new cars, the certificate of conformity and user manual also clearly indicate the standard, such as China 6a being a transitional standard introduced in 2019, while China 6b is stricter and became mainstream after 2020. When choosing a car, it's important to review these documents or ask the dealership salesperson to avoid purchasing the wrong one. During daily use, the environmental green label on the windshield also indicates the emission level. Upgrading to China 6 is much better for the environment, as it reduces pollution. I've checked this way for both cars I bought in recent years, and it's quite straightforward.
During car repairs, I've encountered many inquiries about locating the China VI emission standard mark. Primarily, check the nameplate sticker under the hood where 'China VI' is printed in large characters. Alternatively, the VIN code can assist identification - decoding tools make it instantly clear. The vehicle conformity certificate is the definitive authority, explicitly stating the emission standard in black and white. China VI is divided into phases a and b, with b having stricter requirements. Post-2023 vehicles almost universally comply with phase b, with detailed identification methods explained in the owner's manual. I recommend owners periodically verify their standard to avoid inspection or registration issues - it's a simple DIY check by lifting the hood. Don't cut corners, as this directly impacts smooth annual inspections.
