What does VI represent in the national emission standards?

[LaPresley]

VI represents China VI (National 6) emission standard. The methods to check the China VI standard are: 1. Check the vehicle's environmental protection compliance label; 2. Check the page where the vehicle certification number begins; 3. Estimate the vehicle's emission standard based on its manufacturing year; 4. Use the original or copy of the motor vehicle registration certificate to inquire at the local vehicle management office. The China VI standard is established to prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. The emission limits for China VI are: 1. Carbon monoxide emission limit: 700mg; 2. Non-methane hydrocarbon emission limit: 68mg; 3. Nitrogen oxide emission limit: 60mg; 4. Particulate matter emission limit: 4.5mg.

Oh, I still remember the first time I saw the 'VI' symbol—it was while studying my new car's manual. It actually represents China's Stage VI emission standard, commonly known as 'China 6.' As someone with a bit of interest in cars, I think understanding this is quite important: China's emission standards have evolved from China 1 all the way up to the current China 6. 'VI' is the Roman numeral for 6, and it was widely implemented around 2019, with the core goal of reducing harmful substances in exhaust emissions, such as nitrogen oxides and particulate matter, which significantly contributes to environmental protection. In the past, driving older cars often resulted in black smoke emissions, but with the improved standards for new vehicles, the air has become cleaner. If you're considering buying a car, I’d recommend prioritizing China 6-compliant models—not only do they comply with regulations, but they can also save you some fuel costs and hold better resale value in the used car market. This kind of standard upgrade reflects the country's emphasis on environmental protection and drives technological innovation in the automotive industry.

When I changed my car, I noticed the VI logo, which represents the China VI emission standard. As an ordinary car owner, I find it quite intuitive: VI is the Roman numeral for 6, directly corresponding to the sixth phase standard. The China VI standard has been implemented since 2019 and is much stricter than the previous China V, such as reducing carbon dioxide emissions to make urban air cleaner. Personally, after driving a China VI-compliant car, I've noticed slightly lower fuel consumption and reduced noise, which makes for a great experience. Checking vehicle information is simple—just look at the nameplate or environmental label. The benefit of this standard is that it encourages innovation among car manufacturers, leading to new models that are more energy-efficient and eco-friendly. Overall, the China VI (VI) is a positive change that helps make our daily driving greener and more efficient, and it's definitely worth recommending.

VI stands for China 6, the sixth emission stage. The China 6 standard was implemented in 2019, and the VI logo is commonly seen on vehicles, indicating strict environmental requirements that help reduce pollution. After the upgrade, air quality has improved. I drive a China 6 vehicle, and there's less exhaust when starting up, making city driving more pleasant. This is beneficial for the environment, simple and easy to understand.
