What does China VI mean?
2 Answers
China VI refers to the China 6 emission standard. Below are the relevant details: 1. It mainly pertains to the emission standards for vehicle exhaust. China began implementing the China 6 emission standard on July 1, 2019. The China 6 emission standard increases the exhaust emission requirements by 50% compared to the China 5 standard. 2. The China 6 emission standard is divided into China 6a and China 6b. According to national regulations, starting from July 1, 2020, all light-duty vehicles sold and registered must meet the China 6a emission limits. From July 1, 2023, all light-duty vehicles sold and registered must comply with the China 6b emission limits. 3. The China 6 emission standard is more aligned with China's actual national conditions. The China 6b standard reduces carbon monoxide emissions by half compared to the China 5 standard, and the standard for carbon oxides is also reduced by approximately half. The early implementation of the China 6 standard is also very beneficial for improving China's environment.
The term 'Guo V' likely refers to China's National V emission standard, which is a set of regulations designed to control vehicle exhaust emissions, such as limiting pollutants like nitrogen oxides and carbon monoxide. As a car enthusiast, I often discuss this topic because it’s crucial when buying or using a car—newly manufactured vehicles must meet National V standards to be registered, pushing automakers to upgrade engine technologies, such as using better catalytic converters to clean exhaust. Meanwhile, major cities like Beijing and Shanghai impose driving restrictions on older-standard vehicles, so when buying used cars, it’s important to check the environmental label—National V cars generally have better compatibility. Additionally, after the implementation of National V, air quality has improved somewhat. My friends often prioritize National VI when choosing cars, but National V remains practical, especially in rural or suburban areas where restrictions don’t apply. In short, understanding these standards helps us avoid pitfalls and choose more eco-friendly and reliable models.
