What are the symbols for China V and China VI?

[Peeta]

The symbol marks for China 5 and China 6 are "China V" and "China VI" respectively in English representation. The following are the differences between the two: 1. Emission limits: "China VI" adopts the principle of fuel neutrality, meaning that regardless of the fuel used, the emission limits are the same. However, in the previous "China V" stage, the emission standards for diesel vehicles and gasoline vehicles were different. Moreover, the limit requirements of the "China VI standard" are about 40% to 50% stricter than those of "China V". 2. Emission standards: Compared with China V, the China VI standard reduces nitrogen oxides by 77% and particulate matter by 67%, introduces a limit requirement for particle number (PN), and tightens the requirements for the durability of emission control devices and on-board diagnostic systems (OBD). However, the emission standards for the "China VIa" stage are basically the same as those for "China V", only taking the strictest values from the "China V" emission requirements. 3. Regulatory requirements: China VI puts forward stricter compliance supervision requirements, including type inspection and information disclosure, production consistency inspection, new production vehicle inspection, in-use vehicle compliance inspection, etc., and simplifies the compliance determination method.
