What does China 6 mean for automobiles?
3 Answers
China 6 refers to the regulations on the emission limits of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot from vehicle exhaust. It is a standard established to prevent pollution caused by the exhaust of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. The methods to check China 6 compliance are: 1. Check the new vehicle's certificate of conformity; 2. Check the accompanying environmental information; 3. Query the VIN code online. The content of the China 6 emission standard includes: 1. Carbon monoxide content is 500 milligrams per kilometer; 2. China 6 fine particulate matter content is 3 milligrams; 3. Nitrogen oxides content is 35 milligrams; 4. Non-methane hydrocarbons content is 35 milligrams.
I've driven many cars and recently switched to a new one compliant with China 6 emission standards. Simply put, China 6 is the latest environmental regulation set by the Chinese government for vehicle emissions, divided into two phases: China 6a and China 6b. Its goal is to significantly reduce pollutants like nitrogen oxides and particulate matter in exhaust gases. Previous China 5 standards were more lenient, while China 6 is much stricter, especially with China 6b being fully implemented from 2023, requiring new cars to meet European emission standards. This brings substantial benefits for ordinary people – after choosing a China 6 compliant car, I noticed no difference in city driving, but fuel consumption might be slightly lower, and it passes annual inspections more easily because the detector readings are cleaner. In major cities, non-China 6 vehicles might face driving restrictions or be denied license plates. When buying a car, I recommend checking the emission label on the compliance certificate and prioritizing China 6b. This not only supports environmental protection but also safeguards your health. In the long run, before electric vehicles become widespread, China 6 serves as a transition – driving it to suburban areas noticeably improves air quality.
I drive to work every day and just researched the China 6 standard recently. It's an automotive emission regulation implemented in China since 2019, called the China 6 standard, aiming to reduce pollution and improve air quality. There are two phases: a and b, with b having stricter requirements. In practical use, I haven't noticed any difference - China 6-compliant cars run just as smoothly, but the benefits include lower emissions, easier annual inspections in big cities, and sometimes even better fuel efficiency. A friend who bought a China 6b car has been driving it for a year and actually saw improved fuel consumption instead of increased. When choosing a car, opt for China 6 models - many new cars come with it as standard now without significant price increases. With government policy support, older non-China 6 vehicles might face phase-out, so upgrading helps avoid future hassles. Remember that the China 6 standard also has fuel requirements - using matching fuel ensures effective emission reduction. Protecting the environment is everyone's responsibility.
