The present research work aimed to analyse the performance and emission characteristics of a single cylinder, air cooled, compressed injection diesel fuelled with Jatropha methyl ester blends with Diethyl Ether (DEE) and Isobutanol (IB) additives. Each additive was added in the proportion of 5% and 10% by volume. Experiments were conducted with diesel, B20 and B30 JME (Jatropha Methyl Ester) blends added with selected additives. With these additives, the fuel properties improved. The engine test results showed an improvement in all the performance and emission characteristics with the fuel added and with additives. B20 + 10% DEE showed a better specific fuel consumption, brake thermal efficiency and lower NOx emissions. B30 + 10% IB had shown better CO, CO₂ and O₂ emissions.

本研究工作旨在分析单缸，风冷，压缩喷射柴油机的性能和排放特性，该柴油机由麻风树甲酯与二乙基醚（DEE）和异丁醇（IB）添加剂混合而成。每种添加剂以5体积％和10体积％的比例添加。实验是在柴油，B20和B30 JME（麻疯树甲基酯）混合物中加入选定的添加剂进行的。使用这些添加剂，可改善燃油性能。发动机测试结果显示，添加燃料和添加添加剂后，所有性能和排放特性均得到改善。B20 + 10％DEE显示出更好的比燃料消耗，制动器热效率和更低的NOx排放量。B30 + 10％IB表现出更好的CO，CO ₂和O ₂排放。
