What does China 5 and China 6 mean for cars?
2 Answers
China 5 and China 6 refer to the automobile exhaust emission standards. More knowledge about automobile exhaust emission standards is as follows: 1. Automobile exhaust emission standards regulate the content of harmful gases such as carbon monoxide, PM, and carbon smoke emitted from automobile exhaust. The larger the number, the more environmentally friendly the automobile exhaust is. 2. The difference between China 5 and China 6 mainly lies in the reduction degree of harmful substances in exhaust emissions. The China 6 standard is an upgrade of the China 5 standard, and it will become one of the strictest standards in the world. Compared with the China 5 standard, China 6 strictly controls the emission limits of pollutants. Under the exclusion of working conditions and test influences, the carbon monoxide emissions of gasoline vehicles are reduced by 50%, the emission limits of total hydrocarbons and non-methane total hydrocarbons are reduced by 50%, and the nitrogen oxide emission limits are tightened by 42%.
China's National 5 and National 6 standards are simply our country's vehicle emission regulations. When I recently changed cars, I specifically looked into this. National 5 was implemented around 2017, while the stricter National 6 standards were rolled out in batches after 2019. These mainly limit pollutants like carbon monoxide and nitrogen oxides in exhaust emissions to reduce pollution. When buying a car, you need to check this label carefully. National 6 models might cost more upfront, but they save fuel expenses in the long run due to more advanced technology. Especially in cities, National 6 vehicles help reduce smog problems and are better for people's health. In the used car market, National 5 vehicles have depreciated in value due to new registration restrictions under current regulations. I recommend prioritizing National 6 when choosing a car - it's both environmentally friendly and practical, making it much more cost-effective in the long term.
