What is the symbol for the China VI emission standard?
1 Answers
The symbol for the China VI emission standard is VI. On July 1, 2000, China introduced the first national emission standard, China I, which was formulated with reference to European emission standards and aligned with international standards. From China I to China VI, Roman numerals are used as the symbols. Below is an introduction to the emission standards: 1. The implementation of automobile pollutant emission standards aims to reduce vehicle exhaust emissions and environmental pollution. Vehicle exhaust refers to harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot) emitted from exhaust gases. These harmful gases pose significant risks to human health and severely threaten physical and mental well-being. 2. Currently, China has introduced the China VI emission standard, which is considered the strictest emission standard in the country. 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. 3. The China VI emission standard is extremely stringent, and it is believed that the implementation period for this standard will be longer. Many regions have already adopted the China VIa standard ahead of schedule.
