On July 2000 1, the state issued the first national emission standard, which was formulated with reference to European emission standards and met international standards. The symbols from country one to country six use Roman numerals.
The implementation of automobile pollutant emission standards is to reduce automobile exhaust emissions and environmental pollution. Automobile exhaust refers to harmful gases such as CO (carbon monoxide), HC+ nitrogen oxides (hydrocarbons and nitrogen oxides) and PM (particulate matter, smoke and dust) discharged from the exhaust. These harmful gases do great harm to human body and seriously threaten human physical and mental health.
At present, China has started the national six emission standards. Compared with the national five emission standards, the national six emission standards should be the most stringent first emission standards in China. China ⅵ emission standard is divided into two stages, namely, China ⅵ emission standard A and China ⅵ emission standard B, which are planned to be implemented uniformly throughout the country on July 1 day, 2020 and July 1 day, 2023 respectively.
The national six emission standards are extremely strict. I believe that it will take longer to implement the national six emission standards. At present, many areas have already implemented the National Six Emission Standard A in advance. For areas like Beishangguang, the implementation time is much earlier.
