1985年末,我国农机总动力已达2.84亿马力,比1980年末增长42%。但由于同期的燃料油产量增长较慢,农机用油的供需矛盾已日渐加剧。以湖北省为例,1985年,柴油机每马力的年供柴油量已降至40公斤左右,只是1980年供油量的2/3。乌桕是我国特有的亚热带树种,分布遍及湖北、浙江、广西、贵州等十七省区,年产桕籽约一亿公斤。桕籽表面含桕脂(“皮油”),种仁含梓油,全籽含油率为46.5%-47.3%。研究用梓油作为柴油机的代用燃料的可能性,对解决农机燃料的供需矛盾,具有实际意义。
By the end of 1985, the total power of agricultural machinery in our country reached 284 million horsepower, an increase of 42% over the end of 1980. However, the contradiction between the supply and demand of agricultural machinery oil has been aggravated by the slow growth of fuel oil production over the same period. Take Hubei Province as an example. In 1985, the annual supply of diesel per horsepower for diesel engines dropped to about 40 kg, only 2/3 of that for 1980. Blackbird is a subtropical species endemic to our country, distributed throughout seventeen provinces and autonomous regions such as Hubei, Zhejiang, Guangxi and Guizhou with an annual output of about 100 million kilograms. Sesame seed surface contains grease (“skin oil”), seed kernel oil containing Zi, the whole seed oil rate of 46.5% -47.3%. Studying the possibility of Catalpol as a substitute fuel for diesel engine has practical significance for solving the contradiction between supply and demand of agricultural fuel.
