What is the equivalent of Euro VI in China's emission standards?
2 Answers
Automotive environmental Euro VI is equivalent to China's National VI-A emission standard, but it is not as stringent as the National VI-B emission standard. In China, the European emission standards have been widely adopted. The Euro VI emission standard was introduced in 2014, while China's National VI emission standard was proposed by the Ministry of Environmental Protection in December 2016. Compared to National V, the National VI standard is nearly 50% stricter in terms of pollutant emission limits, with the same requirements applying to diesel vehicles. In terms of data, carbon monoxide emissions will be reduced by 50% from the previous baseline, with similar reductions for total hydrocarbons and non-methane hydrocarbon emissions. Nitrogen oxide emissions are required to decrease by approximately 42%.
When it comes to automotive environmental standards, Euro VI represents the sixth-stage European emission regulations, which impose strict limits on nitrogen oxides and particulate matter in exhaust gases. In China, it basically corresponds to the China VI standard, as China VI has adopted the technical requirements of Euro VI, making the two very similar in terms of pollutant emission limits. In my practical work, I often encounter car owners who are confused about this issue. Actually, when purchasing a car, you can check the environmental label or the compliance certificate—if it states China VI, it means it meets the Euro VI level. The promotion of China VI is currently in full swing, with many new car models adopting this design, significantly reducing urban air pollution. However, it's important to regularly check the emission system during maintenance to avoid exceeding standards due to aging. In short, understanding these standards can help you choose a greener car.
