植物油作柴油机燃料的研究课题已于去年底通过部级鉴定。根据贵州省山地农机所四年多的研究表明,菜籽油作为柴油机、特别是95系列柴油机和其它间接喷射式柴油机的燃料,效果良好。例如,195柴油机用本省产的菜籽油,柴油机工作平稳,出力不降,排烟、排温都与柴油差不多。由于其热值比柴油低约10％,所以油耗率稍高。植物油与柴油可以任意比例混合。因其油性好,不存在精密偶件过量磨损问题。使用菜籽油时,发动机不需改动。作应急燃料短期使用菜籽油时,应注意以下几点:
The research topic of vegetable oil for diesel fuel passed the ministerial level appraisal at the end of last year. According to a study conducted by a mountain farm machinery company in Guizhou Province for more than four years, rapeseed oil works well as a fuel for diesel engines, especially for 95 series diesel engines and other indirect injection diesel engines. For example, 195 diesel engine with rapeseed oil produced in this province, diesel engine work smoothly, output does not drop, exhaust, exhaust temperature are almost diesel. Fuel consumption rate is slightly higher because its calorific value is about 10% lower than diesel. Vegetable oil and diesel can be mixed in any proportion. Because of its good oily, there is no problem of excessive wear of precision couplings. The use of rapeseed oil, the engine does not need to change. Emergency fuel short-term use of rapeseed oil, we should note the following:
