What does China 6 mean?
2 Answers
China 6 refers to the requirement that a vehicle's emission standards meet the specifications of the sixth phase of the national emission standards. The China 6 emission standards were gradually implemented starting from the end of 2019. The national emission standards are categorized as: China 1, China 2, China 3, China 4, China 5, and China 6. The higher the number, the more environmentally friendly the vehicle's exhaust emissions are. The latest national standard introduced is the sixth phase emission standard, which is more stringent, with lower limits on various harmful gases. Vehicle emission standards regulate the levels of harmful gases emitted from vehicle exhaust, such as carbon monoxide, hydrocarbons, and nitrogen oxides. The purpose of setting these standards is to curb the production of these harmful gases, encouraging automobile manufacturers to improve emission standards and reduce the generation of harmful gases.
Well, China 6 is actually the sixth phase of China's vehicle emission standards. I've looked up a lot of information, and it's a new set of rules set by the government for new vehicle emissions, requiring much fewer pollutants in the exhaust. Specifically, it includes controlling carbon monoxide, nitrogen oxides, and those tiny particulate matters, making cars emit less dirty stuff. This thing was fully implemented starting in 2019, divided into China 6a and China 6b phases, with the b phase being stricter. For example, gasoline cars must be equipped with particulate filters to clean the exhaust. I think the reason is that environmental issues are too severe, with heavy smog in big cities, so the government wants to control vehicle pollution from the source. For car owners, China 6 vehicles might be a bit more fuel-efficient and technologically advanced, but they are more expensive when buying, and the resale value of older China 5 cars has dropped. In the long run, it's good, promoting the development of new energy vehicles and making the air cleaner. I recommend choosing China 6 vehicles, especially for new purchases, to avoid trouble with policy changes.
