When did China 4 start?

[DiBentley]

China 4 emission standards started in 2011. Here are the specific methods to check which emission standard a vehicle belongs to: 1. Check the vehicle's environmental protection label, which usually has a clear mark on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring the original or a copy of the vehicle registration certificate to the local vehicle management office for inquiry. 4. For new vehicles, check the vehicle's factory certificate of conformity, which is usually kept at the vehicle management office. Therefore, it is recommended to make a copy for backup when purchasing a car. 5. Make a rough distinction based on the year the vehicle was registered. Most vehicles registered after 2008 are China 4, vehicles registered in 2007 could be either China 3 or China 4, vehicles registered before 2007 are mostly China 3 or China 2, and vehicles registered before 2005 are mostly China 2.
