What does China V and China VI mean?
2 Answers
China V is China 5, and VI is China 6. Both China V and China VI refer to the national automobile emission standards issued by the government, with the full name being Limits and Measurement Methods for Emissions from Light-duty Vehicles. China V and China VI were established at different stages, with the purpose of controlling and reducing vehicle pollutant emissions and improving ambient air quality. The differences between China V and China VI are: 1. The sulfur content in China V and China VI standard gasoline is different. The upper limit of sulfur content in China V standard gasoline is 10 mg per kilogram, while in China VI standard gasoline, it is 50 mg per kilogram; 2. The durability mileage for China V and China VI standards differs. It has been increased from the original 80,000 kilometers under China V standard to 160,000 kilometers under China VI standard. Within 160,000 kilometers, vehicle pollutant emissions should meet the limit requirements of this standard.
I often see questions about China V and China VI standards. These actually refer to the stages of China's vehicle emission standards. China V is the National Phase 5 standard, implemented around 2017, requiring lower emissions of pollutants like nitrogen oxides and particulate matter. China VI is the National Phase 6 standard, gradually implemented starting in 2020, with stricter regulations, higher pollutant limits, and requirements for more efficient exhaust after-treatment technologies. Having driven for over a decade myself, I noticed that after upgrading to a China VI-compliant vehicle, the engine ran smoother and fuel consumption slightly decreased. The standard upgrades primarily aim to improve air quality, reduce smog and health risks, with minimal impact on daily driving. However, when buying new cars, it's important to choose models compliant with the latest standards to avoid urban driving restrictions. I recommend regularly checking your vehicle's emission system to prevent minor issues from escalating into major problems.
