How to Identify China IV and China V Vehicles?

[McHeidi]

Check the vehicle's environmental protection label, which has clear markings on the back. Below are the differences between China IV and China V: Exhaust Emissions: Compared to previous standards, China V regulations reduce nitrogen oxide (NOx) emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles compared to China IV. Emission Standards: The China V emission standard reduces nitrogen oxide (NOx) emissions by 28% compared to China IV, and the combined hydrocarbon and nitrogen oxide (HC+NOx) index is lowered by 23%. For diesel vehicles, particulate matter (PM) concentration is reduced by 82%, and the new particulate number (PN) testing is specifically targeted at diesel vehicles, with PN standards only applicable to diesel vehicles.
