What is the emission standard for vehicles from 2006?

[StPreston]

Vehicles from 2006 are generally compliant with either China II or China III emission standards. Methods to check a vehicle's emission standard include: 1. Review the motor vehicle conformity certificate; 2. Check the accompanying vehicle list; 3. Visit the official website for motor vehicle exhaust pollution supervision and management; 4. Inspect the back of the environmental protection label on the vehicle's front windshield; 5. Bring the vehicle registration form to the local vehicle management office for inquiry. Major automobile emission pollutants include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as the active layer of catalytic converters, secondary air injection, and exhaust gas recirculation systems with cooling devices, these pollutants are controlled and reduced to levels below the prescribed standards.
