Differences between China 5 and China 6 Emission Standards
2 Answers
Here are the differences between China 5 and China 6 emission standards: 1. Different requirements for carbon monoxide emissions: (1) China 5 vehicles have a carbon monoxide content of 1000mg per kilometer. (2) China 6 vehicles have a carbon monoxide content of 500mg per kilometer. 2. Insufficient control levels: (1) The emission control level of the China 5 standard is equivalent to the fifth-stage emission standard currently implemented in Europe. (2) The China 6 standard emission control level is formulated to prevent environmental pollution caused by exhaust emissions from compression-ignition and gas-fueled spark-ignition engine vehicles and to protect human health.
The main difference between China 5 and China 6 emission standards lies in their stringency. As a car owner, I've noticed that China 6 vehicles have stricter emission limits during daily driving, with significant reductions in carbon monoxide and nitrogen oxide emissions, which noticeably improves urban air quality. China 6 also introduces real-driving emission tests, unlike China 5 which only conducts laboratory simulations, making fuel consumption and exhaust performance assessments more realistic. Although China 6 cars are slightly more expensive when purchasing, I believe it's worth it because they may have lower fuel consumption, saving money in the long run. China 5 vehicles face more restrictions in big cities, possibly unable to be transferred in, which affects their resale value. In the long term, upgrading standards reduces the risk of smog, allowing everyone to breathe more easily, and also drives automotive technology innovations, such as more energy-efficient designs.
