What is the China V Emission Standard?
3 Answers
China V Standard is an emission standard for vehicle exhaust. The vehicle exhaust emission standard regulates the content of harmful gases such as carbon monoxide, PM, and soot emitted from vehicle exhaust. The higher the number, the more environmentally friendly the vehicle's exhaust is. Requirements of the China V Standard: The carbon monoxide emission per kilometer driven must not exceed 1000 milligrams; the non-methane hydrocarbon emission per kilometer driven must not exceed 68 milligrams; the nitrogen oxide emission per kilometer driven must not exceed 60 milligrams; the fine particulate matter emission per kilometer driven must not exceed 4.5 milligrams. Differences between China V and China VI: Different emission limits, different prices, and different scrapping time limits.
The China 5 emission standard is a vehicle pollutant regulation implemented nationwide around 2017 in China. I understand it aims to reduce harmful substances in exhaust gases such as carbon monoxide, hydrocarbons, and nitrogen oxides. Compared to the China 4 standard, China 5 imposes stricter requirements—for instance, the carbon monoxide emission limit is nearly halved, which compels new vehicles to incorporate improved engine technologies and high-efficiency catalytic converters during design. As an ordinary car owner, I pay special attention to this label when purchasing a car because new vehicles generally comply with China 5. However, in the used car market, vehicles meeting China 4 or below face restrictions on registration in some cities, leading to a sharp price drop, so caution is needed when changing cars. From an environmental perspective, I believe this is beneficial as it helps improve air quality and reduces the health impacts of smog, especially amid urbanization. Achieving the standard may require more advanced components, potentially raising maintenance costs slightly, but in the long run, it promotes the development of green transportation.
After driving for over a decade, I'm quite familiar with the China 5 emission standards. Implemented nationwide in 2017, these Chinese automotive emission regulations aim to control tailpipe pollutants like carbon monoxide and nitrogen oxides at lower levels, such as setting nitrogen oxide limits below 0.06 grams per kilometer. Compared to the previous China 4 standard, China 5 vehicles emit cleaner exhaust. I've witnessed the changes in the used car market firsthand—China 4 vehicles' prices plummeted, with some areas even banning them from roads. That's why I insisted on choosing a China 5 compliant car when upgrading—not only does it hold value better, but it also saves future hassles. Technically speaking, automakers had to enhance catalytic converter and fuel system designs, which might require specialized maintenance during routine servicing. The environmental benefits are evident—urban air quality has genuinely improved, and I feel more at ease driving such vehicles. When purchasing a car, thorough research is essential to avoid risks associated with older standard vehicles.
