In order to use coconut oil as a diesel fuel, the manufacturing process, the fuel properties and the diesel combustion characteristics of coconut oil' methyl ester (CME)are investigated. CME is made by alkyl catalyst transesterification with water washing. From the experimental analysis, it is shown that the reaction conditions of transesterification from coconut oil to CME to satisfy the EU standard of bio-diesel are that the ratio of methanol amount to its stoichiometric value is 1.8 to 2.0, the KOH amount is 1% mass to coconut oil, the reaction temperature is 60℃, and the reaction time is one hour. CME has low kinematic viscosity and high volatility compared to RME and PME. The pour point of CME is -5.0℃ and it is not reduced by adding the pour point depressant.The combustion characteristics and exhaust emissions of CME are investigated using a single cylinder direct injection diesel engine, and are compared to PME, RME and JIS No.2 gas oil. The injection timing and ignition delay o … More f CME are almost the same as those of JIS No.2 gas oil. The thermal efficiency of CME is almost the same as the other test fuels. The exhaust emissions (HC, CO, NOx and Smoke) of CME are low compared to the other test fuels due to the higher oxygen content of CME. Especially, at 100% load condition, about 50% reduction in smoke emission is found in CME compare to that of JIS No.2 gas oil. From the practical viewpoint, a blend of 20% CME with 80% JIS No.2 gas oil (CME-B20) is tested. The pour point of CME-B20 is -12.5℃, is same as that of JIS No.2 gas oil. The CO, HC and Smoke emissions of CME-B20 are lower than those of JIS No.2 gas oil.The exhaust emissions and carbon deposit in combustion chamber of diesel engine continuously operated for 50 hours by fuelling CME, CME-B20, RME and JIS No.2 gas oil are investigated. The carbon deposit in combustion chamber after 50 hour run for CME is about 60% higher than that for JIS No.2 gas oil. The carbon deposit of CME-B20 after 50 hour run is slightly lower than that of CME. The acid value of lubricant engine oil after 50 hour run for CME is almost the same as that for the gas oil. It is considered that the carbon deposit of CME must be investigated in detail with the carbon deposit formation mechanism in combustion chamber.From the experimental results, it is concluded that CME is a good alternative fuel as diesel fuel compared PME and RME.

为了使用椰子油作为柴油，研究了椰子油甲酯（CME）的制造过程，燃料特性和柴油成分特征。 CME是通过水洗烷基催化剂酯交换来制造的。从实验分析中，可以表明，从椰子油到CME的酯交换条件以满足生物柴油的欧盟标准是，甲基量与其化学计量值的比率为1.8至2.0，KOH量为1％的质量为1％质量与椰子油，反应温度为60°，反应时间为一小时。与RME和PME相比，CME具有低运动粘度和高波动性。 CME的倒数为-5.0℃，并且不会通过添加倾角降压剂来减少它。使用单个气缸直接注射柴油发动机研究了CME的混合物特性和排气排放，并将其与PME，RME和JIS 2号气体油进行比较。注射时间和点火延迟o…更多的F CME几乎与JIS 2号气体油相同。 CME的热效率与其他测试燃料几乎相同。与其他测试燃料相比，由于CME的氧含量较高，CME的排气排放（HC，CO，NOX和烟）较低。特别是，在100％的负载条件下，在CME中发现烟气排放量约为50％，与JIS 2号气体油相比。从实际的角度来看，测试了20％CME与80％JIS No.2气体油（CME-B20）的混合物。 CME -B20的倒数为-12.5℃，与JIS 2号气体油相同。 CME-B20的CO，HC和烟气排放低于JIS 2号天然气油。通过加油CME，CME-B20，RME和JIS 2号天然气油，柴油发动机组合室中的排气排放和碳矿床连续运行50小时。 CME运行50小时后，混合室中的碳沉积物比JIS 2号气体油高约60％。 50小时后，CME-B20的碳沉积略低于CME。 CME运行50小时后，润滑油机油的酸值几乎与气体油相同。据认为，CME的碳沉积必须与组合室中的碳沉积形成机制进行详细研究。从实验结果中，可以得出结论，CME是柴油燃料与PME和RME相比，CME是一种很好的替代燃料。较少的
