The state administration of quality supervision and inspection and the national standards commission issued the mandatory national standards for motor vehicles in phase V. The plan is to be implemented at the end of 2016. The sulfur content is the most critical environmental protection indicator in vehicle gasoline. In order to further reduce the emission of vehicle pollutants, the national V standard lowers the sulfur content limit from 50ppm in the fourth stage to 10ppm, which is 80% lower. Manganese has the potential risk to human health, and the vehicle emission control system will also have adverse effects. According to the principle of prevention, the limit value of the manganese content indicator is reduced from 8mg/L in the fourth stage to 2mg/L, which stipulates that no artificial addition is allowed. In order to further reduce the photochemical pollution caused by the evaporation of gasoline, and reduce the gas intake system of the automobile engine, the national five standard reduced the level of olefin from 28% to 24% in the fourth stage. Due to the decrease of octane number caused by the reduction of sulfur and manganese, the number of gasoline used in phase V was adjusted from 90, 93 and 97 to 89, 92 and 95 respectively. At the same time, considering the development trend of the automobile industry, the index requirements of motor gasoline are added in the standard appendices.
