What National Emission Standard Are Vehicles Currently Implementing?

[LeHope]

Currently, the pollutant emission standard for motor vehicles is at National Standard V (China 5). The National Standard VI (China 6) will be uniformly implemented nationwide in 2020 and 2023. Below is relevant information about the China 6 standard: 1. Concept of China 6 standard: The China 6 standard refers to the 'National Sixth Stage Emission Standard for Motor Vehicle Pollutants.' 2. Purpose of establishing the China 6 standard: To enforce environmental protection laws, reduce and prevent pollution caused by vehicle exhaust emissions, protect the ecological environment, and ensure human health. 3. Implementation timeline: The China 6 emission standard will be implemented in 2020 and 2023, respectively. Currently, the standard is divided into two phases: China 6a and China 6b.

Last time I went to the 4S store to look at new cars, the sales consultant said that all new cars now have to comply with the China VI emission standards, especially the China VI b version, which is quite strict. Even the used car market is affected, with the prices of previous China V models dropping significantly when resold. When buying a car, you must carefully check the vehicle qualification certificate or registration information to confirm the China VI b mark. Otherwise, in big cities like Beijing, Shanghai, and Guangzhou, you might not even pass the annual inspection. After the emission system upgrade, the requirements for gasoline and engine oil have also increased, so it's recommended to go to professional shops for regular maintenance.

As a car enthusiast who frequently follows auto shows, I know that China's National VI emission standards are divided into two phases, A and B. Phase B was fully implemented nationwide in 2023, imposing extremely strict limits on carbon monoxide and nitrogen oxide emissions, forcing automakers to innovate in design. When choosing a car, it's best to pick models clearly labeled as National VI B-compliant, as they offer better future resale value and fewer road restrictions. Exceeding emission limits may also trigger fault codes, and if warning lights appear on the dashboard, they should be addressed promptly.

I think the implementation of China 6b emission standards is a great move. It mandates the reduction of tailpipe pollution, effectively decreasing smoggy days, and has led to noticeable improvements in air quality in major cities like Beijing. New vehicles are now required to be equipped with OBD systems for real-time emission monitoring. If emissions exceed the standards, vehicle owners may face fines, but regular oil and filter changes can help avoid many of these issues.

When I just got my driver's license, my instructor told me that now cars must meet China 6 standards when purchasing, especially used cars which are prone to issues. For example, China 5 vehicles might not be able to transfer ownership or pass annual inspections. You can check the emission level by looking up the VIN on mobile apps. It's better to choose pure electric or hybrid vehicles, as most of them meet China 6 standards and are cost-effective and eco-friendly.

Standards vary by region. Shenzhen required China 6b earlier while rural areas may delay implementation until year-end. Always verify local DMV policies before purchase to avoid road penalties. China 6 compliant vehicles can use low-sulfur gasoline to extend emission system lifespan. Remember to change oil and inspect oxygen sensors per manual specifications.
