What does China National V and VI mean for vehicles?
2 Answers
China National V and VI refer to the emission standards for vehicle exhaust, which regulate the content of harmful gases such as carbon monoxide, nitrogen oxides, and particulate matter emitted from vehicle exhaust. Under the China National V standard, the nitrogen oxide emission limit is 0.18 grams per kilometer, the particulate matter concentration limit is 0.0045 grams per kilometer, and the non-methane hydrocarbon emission limit is 0.23 grams per kilometer. For the China National VI standard, the nitrogen oxide emission limit is 0.16 grams per kilometer, the particulate matter concentration limit is 0.022 grams per kilometer, and the non-methane hydrocarbon emission limit is 0.18 grams per kilometer.
China's National V and National VI are emission standards set by the state, primarily aimed at controlling tailpipe pollution. I think this is quite important for environmental protection. National V limits nitrogen oxides and particulate matter emitted by vehicles, while National VI is even stricter, divided into National VIa and National VIb, requiring approximately a 40% reduction in pollution. After implementation, urban air quality has noticeably improved, reducing smoggy days, so we wear masks less often when going out. Health-wise, children's respiratory issues may decrease, benefiting society as a whole. The government encourages automakers to upgrade technology through subsidy policies. By choosing National VI-compliant vehicles when purchasing cars, we can contribute to environmental protection. In the long run, it promotes sustainable living, helping everyone adapt to green transportation habits.
