What does National VI mean?
2 Answers
National VI refers to the China VI emission standard, which is the automotive emission standard implemented in China. It strictly controls the emission limits of pollutants. Under the exclusion of working conditions and test influences, the carbon monoxide emissions of gasoline vehicles are reduced by 50%, the total hydrocarbon and non-methane hydrocarbon emission limits are decreased by 50%, and the nitrogen oxide emission limits are tightened by 42%. Methods to check the emission standard of a vehicle: 1. Look at the fuel consumption label on the new car; 2. Check the new car's nameplate, find the vehicle model number (a combination of numbers and letters), and take a photo with your phone; 3. Find the engine model number of the new car; 4. Visit the Motor Vehicle Environmental Protection Website, input the vehicle model and engine model to query.
Speaking of China VI, it's the latest generation of vehicle emission standards, officially known as the China 6 Emission Standard. Simply put, it aims to make vehicle emissions cleaner by reducing particulate matter and carbon monoxide. I recall that in China, China VI was gradually implemented starting from 2019, being much stricter than the previous China 5 standard. It requires upgraded engine technologies in new vehicles, such as installing particulate filters or optimizing fuel systems, to reduce harmful substances in exhaust gases. For us car owners, when buying a new car, we need to check the environmental label on the windshield to confirm if it meets China VI standards. Otherwise, driving into restricted zones in cities like Beijing, Shanghai, Guangzhou, or Shenzhen could get you stopped. I often hear friends say that maintaining a China VI-compliant car requires extra attention to fuel quality—using poor-quality fuel can easily clog the filters. Overall, this standard pushes the automotive industry toward greener development, making the air cleaner.
