以菜籽油为燃料 ,对 S195柴油机燃油性能进行了研究。结果表明 :在发动机结构不经改动的情况下 ,燃用菜籽油或菜籽油与柴油的混合油是可行的 ;发动机燃用菜籽油或混合油时 ,其排放污染下降 ,但耗油率均有所上升 ,且燃烧室和喷油嘴积炭较多 ;发动机燃用 5 0 %菜籽油与 5 0 %轻柴油的混合油 ,且供油提前角为 2 0°CA时燃烧性能较好 Using rapeseed oil as fuel, the fuel performance of S195 diesel engine was studied. The results show that it is feasible to use rapeseed oil or rapeseed oil mixed with diesel oil under the condition of unmodified engine structure. When the engine is rapeseed oil or mixed oil, the emission pollution will decrease but fuel consumption Rate increased, and the combustion chamber and fuel injector coke more; engine combustion 50% rapeseed oil and 50% light diesel oil mixture, and the fuel advance angle of 20 ° CA when the combustion performance better
