What Standard Does China VI Refer To?
3 Answers
China VI refers to the China 6 emission standard. Starting from 2019, various cities and regions across the country have gradually begun implementing the China 6 standard. Below is an introduction to the China 6 emission standard: 1. The strictest emission standard: China 6 is known as the most stringent emission standard in history. The implementation of the China 6 standard imposes stricter requirements on pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons. 2. Introduction to China 6a: China 6a serves as a transitional phase to China 6b. The China 6a standard was implemented during the transition period from China 5 to China 6. 3. Requirements of China 6b: It mandates that for every kilometer driven, a car must not emit more than 500 milligrams of carbon monoxide, 35 milligrams of non-methane hydrocarbons, or 35 milligrams of nitrogen oxides.
China VI is the national sixth-stage vehicle emission standard. I've been following vehicle emissions since 2000, and the upgrade from China V to China VI was officially implemented in 2019, bringing significant changes. Previously, China V vehicles emitted more harmful substances, but China VI standards became much stricter, reducing pollutants like nitrogen oxides and particulate matter by nearly half, making driving more eco-friendly. When choosing a car, look for the 'China VI' label on the emission tag—many new cars now display it. I recommend car owners prioritize purchasing China VI-b models, as they meet the strictest requirements and won't face urban driving restrictions. Although the cost of upgrading might be higher, cleaner air benefits everyone. During routine maintenance, pay attention to the emission system to avoid issues that could cause problems during annual inspections. This way, driving becomes worry-free and truly worthwhile.
With over a decade of experience in the automotive world, I've always enjoyed delving into technical details. China VI refers to the national sixth-stage emission standard, which sets new limits for gasoline and diesel vehicles. For instance, particulate matter must be filtered out by over 90% using a GPF (Gasoline Particulate Filter). Compared to China V, the China VI-b phase implemented after 2020 is even stricter, incorporating real-world driving emission tests to ensure consistently low emissions. When purchasing a vehicle, simply look for the VI mark on the conformity certificate, though diesel vehicles may be slightly more expensive after the upgrade. In the long run, this helps reduce PM2.5 levels and improves urban smog conditions, doubling the environmental benefits when combined with the trend toward electric vehicles. Future China VII standards will be even stricter, so tech enthusiasts might want to keep an eye on developments.
