What do China 5 and China 6 vehicles mean?
2 Answers
China 5 and China 6 refer to the national vehicle exhaust emission testing standards. Here is a related introduction to the differences between China 5 and China 6: 1. Different control levels: The emission control level of the China 5 standard is equivalent to the European Stage 5 emission standard currently in effect. The China 6 standard for motor vehicle pollutant emissions is designed to prevent environmental pollution from the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Different release dates: The China 5 standard was released on September 17, 2013. The China 6 standard for motor vehicle pollutant emissions was released on June 22, 2018 (for heavy-duty diesel vehicles). 3. Different issuing departments: The China 5 standard was issued by the Ministry of Environmental Protection. The China 6 standard for motor vehicle pollutant emissions was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine.
When I first bought a car, I was also confused about China 5 and China 6. Actually, these refer to the national vehicle emission standards - China 5 means the fifth phase national standard, while China 6 is the sixth phase with stricter limits on pollutants in exhaust emissions, such as carbon monoxide and particulate matter. I chose a China 6 compliant car because it's more environmentally friendly, easier to drive in big cities like Beijing with fewer traffic restrictions, and I don't need to worry about being barred from entering central areas. In the long run, China 6 cars have better resale value and are easier to sell when trading in. The upgrade in emission standards is mainly to improve air quality, reduce smog, which is crucial for our respiratory health. When choosing, you should consider personal needs - for example, I considered cost-effectiveness. Most new cars now meet China 6 standards, but used China 5 cars might be cheaper. Just remember to check local traffic regulations before purchasing.
