When did the China V emission standard start?

[SanNaomi]

The China V emission standard was implemented in certain regions in phases, by area and stage starting from April 1, 2016, and was enforced nationwide from January 1, 2017. The emission control level of the China V standard is equivalent to the Euro 5 emission standard currently implemented in Europe. The European Union has been enforcing it since 2009, which imposes stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles emitted by motor vehicles. Here is some information about the China V emission standard: (1) The China Fifth Stage Motor Vehicle Pollutant Emission Standard, abbreviated as the "China V Standard". (2) Emission standards are primarily used for testing new vehicles, and cars sold on the market should comply with the emission requirements of the time.
