To determine whether a vehicle meets China III or China IV standards, you can: 1. Check the vehicle's environmental protection label, which has clear markings 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 motor vehicle registration certificate to the vehicle management office for inquiry; 4. For new vehicles, you can find the information in the vehicle's factory certificate. China III refers to the National Stage III Motor Vehicle Pollutant Emission Standards, while China IV refers to the National Stage IV Motor Vehicle Pollutant Emission Standards. Automobile exhaust emission standards regulate the content of harmful gases such as carbon monoxide, nitrogen oxides, and carbon smoke emitted from vehicle exhaust.
