What National Emission Standard Are Vehicles Currently Implementing?
2 Answers
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.
