Methods to distinguish between China 6a and 6b are: 1. Check the relevant content on the vehicle qualification certificate; 2. Review the environmental protection information included with the vehicle; 3. Query through dedicated websites. China 6 refers to the National Sixth Stage Emission Standards for Motor Vehicles, which are established to prevent pollution from the exhaust of compression ignition and gas fuel ignition engine vehicles, protect the ecological environment, and safeguard human health. The impacts of the China 6 standard include: 1. Effectively reducing the gap between laboratory certification emissions and actual usage emissions; 2. Improving the emission control levels of vehicles under actual operating conditions; 3. Effectively preventing cheating behaviors that lead to actual emission exceedances.
