What is the China VI Vehicle Emission Standard?

[NoraFitz]

China VI Vehicle Emission Standard refers to the National Sixth Stage Emission Standard for motor vehicles. The China VI standard is divided into two phases: 6A and 6B. Compared to China VI-A, China VI-B imposes stricter requirements on the emissions of carbon monoxide, non-methane hydrocarbons, nitrogen oxides, and PM particulate matter. Vehicle emission standards refer to the harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter. To curb the generation of these harmful gases and encourage automobile manufacturers to improve their products to reduce the source of these emissions, relevant vehicle emission standards have been established.

As an ordinary person who has been driving for many years, the China 6 standard is China's sixth-stage vehicle emission regulation. Simply put, it's a new rule set by the government to make car exhaust cleaner. Compared to the previous China 5 standard, China 6 is divided into two parts: China 6a and China 6b, with the b phase being more stringent, aiming to reduce pollutants like nitrogen oxides and particulate matter to protect the environment and prevent smog. It has a significant impact on us car owners—newly purchased gasoline or diesel vehicles must comply with it, otherwise, it's hard to get licensed. When I last changed my car, I specifically checked for the China 6 label and thought it was quite worthwhile since it contributes to cleaner air and even saves some fuel costs. Maintenance has also changed; China 6 vehicles have more sensors in their systems, making them prone to fault codes, so repairs require caution to avoid improper modifications. Overall, it's progress but adds a bit of hassle.

I have always been an environmental supporter. The China VI standard is the sixth edition of emission control regulations for vehicles in China, with its core objective being to significantly reduce tailpipe pollution and improve air quality. It sets stricter limits, controlling the emissions of harmful substances such as carbon monoxide and nitrogen oxides, with particularly noticeable effects on large diesel vehicles. The China VI standard is divided into phases a and b, with phase b fully implemented in 2023, helping to reduce urban smog and greenhouse gases, supporting the carbon neutrality goal. As a citizen, I recommend everyone prioritize China VI-compliant vehicles when choosing a car. Although new cars may be slightly more expensive, they save fuel and promote health in the long run. After its promotion, there has been a noticeable improvement in air quality in places like Beijing, proving that environmental policies truly work.

Having been in the automotive industry for a while, I'm quite familiar with the China 6 standard: the sixth upgrade of China's motor vehicle emission regulations, primarily targeting new vehicle manufacturing and sales. China 6 is stricter than the old standards, controlling pollutant limits such as hydrocarbon and particulate matter concentrations, aiming to prevent pollution and regulate the market. It has two versions, a and b. After version b is implemented, all vehicles sold by dealers must meet the standard. When buying a new car, just look for the China 6 label, and you're good to go. Non-compliant vehicles may face registration restrictions. In practice, it pushes manufacturers to adopt new technologies, such as high-efficiency catalysts, making cars more energy-efficient and environmentally friendly, giving customers peace of mind when purchasing.
