디이겔엔진의 代替燃料 로서 大豆油는 大豆油의 높은 粘性에 起因하는 문제점이 지적되고 있다. 이의 해결방법으로 大豆油와 디이제러油결 混合, 大豆油의 에스테르化 그리고 디이젤油 添加劑의 添加 등이 제시되고 있다. 本硏究는, 大豆油, 그의 에틸 에스테르 그리고 이러한 代替燃料의 디이젤油와 混合物 또는 그 混合物 의 添加劑와의 混合物의 粘性學的 性質과 그 크기를 實驗的 方法으로 구하였다. 그 결과 상기의 液休는 모두 뉴톤니안 液休이고, 添加劑는 상기 混合物의 粘性을 낮추는데 별로 효과가 없는 것으로 .판단되었다. N/A

N/A Performance of a screw press was investigated experimentally with soybeans of various temperatures in order to find out a proper temperature of soybean to extract the oil by the mechanical method. Crude oil extracted by the screw press was chemical analyzed to determine a level of processing the oil for the oil to be used as a fuel for a compression ignition, eagine. The crude on was degummed and dried by a plant type laboratory experimental setup to decicide whether the processes are effective to improve quality of the oil as a fuel. The degummed oil and the degummed and dried oil were also chemically analyzed and were compared with the crude oil and the commercially degummed and dried soybean oil, The results are as follows: 1. In extraction of soybean oil by a screw press, heating soybeans is effective to increase oil production and to decrease energy consumption of the press. A proper temperature of soybean to extract the oil by the press was determined as about 50℃. 2. Soybean oil production and electric energy consumption of the press are about 83 ml and 58 Wh per 1 ㎏ of soybeans heated to about 50℃, respectively. 3. The quality of crude oil produced by the press is similar to that of the commercially degummed and dried oil. The crude oil does not need to be degummed or dried for use as an engine fuel.
