[MacMelanie]

Methods to determine whether a car is China 5 or China 6 standard are: 1. Check the vehicle fuel consumption label; 2. Check the environmental inspection compliance mark. The differences between China 5 and China 6 standards are: 1. Different carbon monoxide emission requirements: China 5 standard allows 1000 mg per kilometer for carbon monoxide; China 6 standard allows 500 mg per kilometer for carbon monoxide. 2. Different particulate matter emission requirements: China 5 standard allows 5 mg for particulate matter; China 6 standard allows 3 mg for particulate matter. 3. Different nitrogen oxide emission requirements: China 5 standard allows 60 mg for nitrogen oxides; China 6 standard allows 35 mg for nitrogen oxides. 4. Different non-methane hydrocarbon emission requirements: China 5 standard allows 68 mg for non-methane hydrocarbons; China 6 standard allows 35 mg for non-methane hydrocarbons.
