What does China V mean for vehicles?

[MariaLee]

China V for vehicles refers to the China V emission standard, which is the abbreviation for the National Fifth Stage Emission Standard for Motor Vehicle Pollutants. It imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Compared to the China IV standard, the China V standard reduces nitrogen oxide emissions from standard light-duty vehicles by 25%, and requires carbon monoxide emissions from gasoline vehicles meeting the China V standard to be no more than 1000 milligrams per kilometer. Vehicle emission standards are established to implement environmental protection regulations, reduce and prevent pollution from vehicle exhaust, protect the ecological environment, and ensure human health. They are designed to control the emission of harmful gases from vehicle exhaust.
