燃料乙醇(下称乙醇),与汽油相比,具有辛烷值高、可燃界限宽、排放中有害物质浓度低,在汽油中以低比例掺烧时对发动机结构不必作改动等优点,因此燃料乙醇作为可再生能源,在当今石油资源供应紧张的情况下,是一种较为理想的汽车燃料,在世界上已得到较大规模的使用,我国已在黑龙江、吉林、辽宁、安徽、河南、广西、河北、山东、江苏、湖北等地开展了乙醇汽油的推广使用工作。但是,乙醇毕竟
Compared with gasoline, fuel ethanol (hereinafter referred to as ethanol) has the advantages of high octane number, wide combustible limit, low emission of harmful substances and no need to modify engine structure when gasoline is mixed at a low ratio. Therefore, fuel As a renewable energy source, ethanol is an ideal fuel for automobiles in the current situation of tight supply of petroleum resources. It has been used on a large scale in the world. China has already used it in Heilongjiang, Jilin, Liaoning, Anhui, Henan, Guangxi , Hebei, Shandong, Jiangsu, Hubei and other places to carry out the promotion of the use of ethanol gasoline.
