1 前言随着国民经济的发展,内燃机在国民经济中尤其是在工农业生产、交通运输以及国防建设中所处的地位越来越高,而作为内燃机燃料来源的石油的储量却是有限的。为了克服能源紧缺的问题除有必要继续致力于改善内燃机性能、提高内燃机效率的研究外,人们也十分关注对内燃机燃料进行改质处理以及应用其它非石油系燃料的研究。早在60年代,美、英、日、西德等国就开始对内燃机燃料进行磁化处理的研究。他们的研究表明:磁化燃油能改善燃烧,降低油耗。国内从80年代初期也开展了磁化燃料的运用研究,并在水运、公路、铁路运输各 1 Introduction With the development of the national economy, the status of internal combustion engines in the national economy, especially in industrial and agricultural production, transportation and national defense construction is becoming more and more high while the reserves of petroleum used as the fuel source of internal combustion engines are limited. In order to overcome the problem of energy shortage, besides the ongoing efforts to improve the performance of internal combustion engines and improve the efficiency of internal combustion engines, much attention has been paid to the research on the modification of internal combustion engine fuels and the application of other non-petroleum fuels. As early as the 1960s, the United States, Britain, Japan, West Germany and other countries began to study the internal combustion engine fuel magnetization. Their research shows that magnetized fuel can improve combustion and reduce fuel consumption. Domestic since the early 1980s also carried out the use of magnetized fuel research, and in water, roads, rail transport each
