[XavierMarie]

Methods to check whether a vehicle meets China 5 or China 6 emission standards are: 1. Check the vehicle's factory certificate; 2. Review the vehicle's environmental standard list; 3. Examine the vehicle conformity certificate. The differences between China 5 and China 6 are: 1. Different carbon monoxide emission levels: China 5 allows 1000mg; China 6 allows 700mg. 2. Different emission limits: China 5's limit is 0.0045g per kilometer; China 6's limit is 0.25g per kilometer. China 5, fully named the National Fifth Stage Motor Vehicle Pollutant Emission Standard, and China 6, fully named the National Sixth Stage Motor Vehicle Pollutant Emission Standard, both regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot emitted from vehicle exhaust.
