What is the symbol for China VI emission standard?
3 Answers
The symbols for China 1 to China 6 emission standards are I, II, III, IV, V, and VI respectively, with China VI being represented as VI. On July 1, 2000, China first introduced the China 1 emission standard, which was based on European emission standards and aligned with international standards, hence the use of Roman numerals for China 1 to China 6 symbols. The functions of the environmental protection label include: 1. Serving as proof of a vehicle's compliance with emission standards; 2. Acting as the basis for determining the periodic environmental inspection cycle of vehicles; 3. Implementing traffic control measures for high-emission vehicles and serving as a pass for vehicles in restricted zones; 4. Providing a basis for relevant authorities to manage vehicle environmental compliance.
I recently bought a new car and carefully checked the nameplate, where I saw the words 'China VI' prominently displayed. This is the official symbol for China's sixth-stage emission standards. It usually appears on the environmental label sticker on the front windshield, and sometimes the body nameplate uses the Roman numeral 'VI' to indicate it. This symbol means the vehicle complies with the latest environmental regulations implemented since 2019, aimed at significantly reducing pollutant emissions such as PM particulate matter and NOx nitrogen oxides. When buying a car, I paid special attention to this label because it reflects the vehicle's environmental performance; China VI-compliant cars not only save fuel but also help reduce urban smog. This was the most important factor for me when choosing a new car, as environmental protection starts with me and supports sustainable development goals. I recommend everyone to regularly check the emission system during car maintenance to ensure it doesn’t exceed standards, making driving more reassuring and protecting the environment.
After years of working on cars, I've encountered various models and often found the 'VI' symbol under the hood or on environmental labels representing the China 6 emission standard. Previously, China 5 was just marked with a V, but now it's upgraded to stricter requirements. Car owners often overlook this, but it's crucial in practical use. Since 2020, the full implementation of China 6b phase has required a significant reduction in vehicle emissions. During repairs, I use diagnostic tools to test values and ensure compliance. This symbol reminds us that automotive environmental protection is progressing, driven by national policies to improve air quality. In routine maintenance, I emphasize replacing air filters and oxygen sensors to keep emissions clean. Simple maintenance by car owners can contribute to environmental protection—don’t let a small symbol lose its original meaning.
