When did China National V trucks start to appear?

Because China only began implementing the China National V emission standards in 2017, most China National V trucks were manufactured after 2017. Additional information: 1. China National V standards: The China National V emission standards impose stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. From China National I to China National IV, each upgrade in standards reduces single-vehicle pollution by 30% to 50%. 2. Differences: Compared to the China National IV standards, the new standards can reduce nitrogen oxide emissions from light-duty vehicles by 25% and from heavy-duty vehicles by 43%. Based on Shanghai's annual vehicle registration volume of approximately 350,000 units, it is estimated that annual new vehicles can reduce nitrogen oxide emissions by about 1,000 tons.
