How to Identify the Letter for China 6 Vehicle Emission Standards?

In China's vehicle emission standards from China 1 to China 5, the corresponding characters are I, II, III, IV, and V respectively, while China 6 is represented as Ⅵ. The implementation of the China 6 emission standard will be divided into two phases: "China 6a" and "China 6b", with corresponding time points on July 1, 2020, and July 1, 2023. In fact, China 6a is only a transitional stage from China 5 to China 6, and by 2023, the China 6 emission standard will be fully implemented. Below are the requirements for the China 6 emission standard: 1. The China 6 standard: The China 6 standard is extremely high and is considered one of the strictest vehicle emission standards globally. Compared to the China 5 emission regulations, China 6 adds limits for nitrous oxide and particulate matter particle counts, and requires a 50% reduction in carbon monoxide content during cold start conditions, a 30% reduction in hydrocarbon content, and a 30% reduction in carbon monoxide content. 2. China 5 vehicles can still be driven after the implementation of China 6 standards: Even after the implementation of the China 6 standard, China 5 vehicles can still be driven on the road, although registration and licensing may become more difficult. For those China 5 vehicles in stock, they will definitely be sold at discounted prices, and the closer the date of China 6 implementation gets, the cheaper they will become.

Checking if a car meets the China 6 emission standard is quite simple. Generally, you can look for stickers or labels on the car body, especially near the door or rear windshield, where there will be an environmental protection label marked 'China VI' indicating it meets the standard. The emission standard is also listed on the vehicle registration certificate—just check carefully to find it. When I bought my car, I paid attention to this because China 6 represents higher environmental requirements and lower exhaust emissions, which is better for air quality, especially in big cities with smog issues. If you can't find it, checking the vehicle manual or entering the VIN on the official website is also convenient. Regular maintenance is crucial too, such as changing the oil and inspecting the exhaust system to help the car maintain the standard. When buying a car, don’t just focus on appearance—emission standards directly affect future usage costs and environmental responsibility.

Car enthusiasts often discuss how to identify the China 6 emission standard in their chats. From my experience, check multiple locations: First, the vehicle nameplate under the rear seat or in the engine compartment – look for the "China VI" marking; Second, the environmental label on the windshield is immediately visible; Also, the Certificate of Conformity in the purchase documents provides detailed specifications. The China 6 standard requires cleaner vehicle emissions, significantly benefiting pollution reduction. For maintenance, use high-quality fuel and perform timely inspections. DIY checks are simple and effortless – just remember the key letters are VI, and don't confuse it with older standards. Sharing this knowledge helps friends choose eco-friendly vehicles, collectively protecting our air.

If you've just started driving and want to know if your car meets China VI emission standards, simply ask the seller or check the emission section on the vehicle registration certificate, which should display the letters 'China VI'. No need to understand technical terms—just confirm those letters indicate low emission standards. Pay attention to this when buying a used car, and opting for a new car is even safer and more reliable.
