What are the symbols for China V and China VI?

[HarrisonRose]

The symbols for China V and China VI are V and VI, respectively. Here is more related information: 1. The symbols from China I to China VI are I, II, III, IV, V, and VI. On July 1, 2000, China first introduced the China I emission standard, which was formulated with reference to European emission standards and aligned with international standards. Roman numerals are used for the symbols from China I to China VI. The implementation of vehicle pollutant emission standards can reduce vehicle exhaust emissions and environmental pollution. 2. Vehicle exhaust refers to harmful gases such as CO (carbon monoxide), HC-NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) emitted from the exhaust. These harmful gases pose significant risks to human health and seriously threaten physical and mental well-being. Currently, the China VI emission standard has been introduced, which is an improvement over the China V standard. The China VI emission standard is divided into two phases, China VIa and China VIb, with nationwide implementation planned for July 1, 2020, and July 1, 2023, respectively.
