Abstract: In order to solve the problem of pollutant emission control of gasoline vehicles in China, the Ministry of Ecology and Environment has issued a new national standard on limits and measurement methods for emissions from gasoline vehicles. It has studied the changes in the national standard, the implementation process of the new regulations, and internal standard recommendations. Vehicle manufacturers should focus on the processes and control points, and set up a framework for the pollutant emission test and control system of newly produced gasoline vehicles under the new regulations to provide a reference for the pollutant emission test and evaluation work of vehicle manufacturers. It also conducts preliminary explorations for improving and innovating China's emission standard system.
