At the beginning of the tests on application of ethanol gasoline in 2001, Chinese government promulgated a national standard, GB 18351-2001 "Ethanol Gasoline for Motor Vehicles". The standard specifies three kinds of ethanol gasoline, namely E10 (90 RON), E10 (93 RON) and E10 (95 RON). There were ethanol gasoline grades (90 RON and 93 RON) and conventional unleaded gasoline(97 RON) available in the areas where tests were carried out. Vehicle owners were worded about the harmful action of ethanol to their vehicles because of lack of knowledge regarding ethanol fuel, and they only refueled their cars with conventional 97 RON unleaded gasoline. This idea might cause unnecessary costs to customers and could bring about difficulty to the tests as well. Besides, some other technical questions emerged during the experimental application of ethanol gasoline, such as water content, ethanol content in gasoline, etc. Based on the experiences accumulated during the application tests, the national standard GB 18351-2001 "Ethanol Gasoline for Motor Vehicles" was revised. The revised edition is designated as GB 18351-2004. 展开更多

Promoting the use of ethanol gasoline is an important approach for China to achieve sustainable and high quality development.Based on the daily air quality data of Tianjin,China,from 2013 to 2020,this paper investigates whether the implementation of the ethanol gasoline policy helped improve air quality using regression discontinuity analysis.We find that the implementation of the ethanol gasoline policy had a very limited positive effect on the overall air quality index(AQI)and no obvious effect on the reduction of particulate matter(PM_(2.5) and PM_(10)).However,the results reveal that the ethanol gasoline policy reduced SO_(2),NO_(2),and CO by about 36%,19%,and 20%,respectively.These findings provide policy insights for other cities in China and other rapidly developing cities in the world to promote the use of ethanol gasoline. 展开更多
