Through analysis on the new standard of automobile gasoline, the difference between the automobile gasoline technical indices of Stage IV and Stage V was presented. The new standards make it clear that the sulfur content of automobile gasoline should be less than 10 mg/kg, manganese content under 0.002 mg/kg, and the olefin content less than 24 Vol%. Also the quality index range of vapor pressure and grades of automobile gasoline are adjusted and quality index of density is added. The transitional period of technical requirements of automobile gasoline of Stage V will last to December 31th, 2017. That means the technical requirements of automobile gasoline of Stage IV will be repealed since January 1st, 2018. The influence of promulgation and implementation of the new standard in improving the automobile gasoline quality of our country and also the impact on refining industry, consumers and inspection work was elaborated. The new standard well satisfied the requirements on automobile gasoline emission standards of Stage V , and the key technical indices of major items match those of“Euro V”standards.
