China draws lessons from European automobile emission standards, and domestic new cars will be marked with European standards for engine exhaust emissions.

The implementation history of automobile exhaust emission standards in China: On July 1 day, 2004, the second national emission standard was implemented nationwide; On July 2007 1, the third national emission standard was implemented nationwide. 20 15 65438+ 10/month 1, the national four emission standards are implemented nationwide.

National III and IV standards refer to Euro III and Euro IV automobile emission standards. Compared with Euro II, Euro III further reduced the emission limit of pollutants. The emission limit of Euro III standard is 30% lower than that of Euro II standard, while that of Euro IV standard is further reduced by 60%.

In order to ensure that the vehicle meets the emission limit requirements stably in use and ensure the durability of vehicle emission control performance, the requirements for on-board diagnostic system (OBD) and in-use vehicle compliance are increased. On June 0, 20 18+ 1 year, China will implement the fifth-stage national four motor vehicle emission standards.

The national five is also the automobile exhaust emission standard, which is equivalent to the European five standard of the European Union. Since 2009, the European Union has implemented stricter restrictions on motor vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide and suspended particulate matter. From country I to country IV, bicycle pollution will be reduced by 30% to 50% every time the standard is raised.

In order to better reduce air pollution, in 2003, Tokyo promulgated the first Japanese law on PM2.5 and below, even stricter than the standards being implemented in Europe and America. On April 1 day, 2006, Japan began to implement the Law on the Regulation of Tail Gas of Special Purpose Vehicles, which was the first law in Japanese history to regulate the exhaust emissions of off-road vehicles.

Later, in September 2009, the Japanese government added the index of PM2.5 to the Japanese air quality standard, which is the same as the American standard. With the continuous implementation and improvement of emission standards and regulations, Japanese automobile exhaust emission control has entered the period of legal regulation, and its air pollution problem has been obviously and effectively solved, which is worth learning from China.
