How to Check Whether a Vehicle Meets China 5 or China 6 Emission Standards?

[SimonFitz]

Methods to check whether a vehicle meets China 5 or China 6 emission standards include: 1. Check the vehicle's factory certificate; 2. Refer to 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 0.0045 grams per kilometer; China 6's limit is 0.25 grams per kilometer. China 5, fully named as the National Fifth Stage Motor Vehicle Pollutant Emission Standard, and China 6, fully named as the National Sixth Stage Motor Vehicle Pollutant Emission Standard, both regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot emitted from vehicle exhaust.
