This report investigated the influence on diesel injection, engine performance, combustion characteristics, emissions, and other characteristics of combustion of single droplets of neat FAME fuels. The experiments used chemical reagents, methyl oleate (OME, C18:1), methyl Laurate (LME, C12:0), and mixtures of methyl palmitate (PME, C16:0) and OME or LME as the base fuels. Notable results obtained are as follows:(1) The bulk modulus was determined by measurements of the speed of sound under low fuel pressure conditions (>40MPa), and the results showed that the bulk modulus of OME was about 7% higher than gas oil. The delay in injection was examined by measuring the time difference between the start of the pressure rise in the injection pipe and the start of injection. With OME and LME there were shorter injection delays than with ordinary gas oil.(2) Engine experiments were carried out with biodiesel fuels derived from unused rapeseed oil, soybean oil, and palm oil. This elucidated the influence on engine performance, combustion characteristics and emissions of the three kinds of raw materials. Compared with gas oil, the FAME fuels showed similar brake thermal efficiencies at high loads, and the smoke densities were significantly lower under whole load conditions. The ignition characteristics were considerably improved when PME was blended with LME or OME.(3) With a suspended droplet combustion technique, the combustion characteristics of FAME droplets were analyzed with images taken by a high speed video camera. It was found that when PME is blended with OME the ignition delay shortens and the speed of combustion increases. During the combustion process, the formed soot was collected on a glass fiber filter and the mass was weighed by a micro balance. The results showed that the soot formation rate(defined as the mass ratio of soot to droplet) with OME is below 15% of that of gas oil droplets.

该报告调查了对柴油注射，发动机性能，燃烧特性，排放和其他整齐燃料燃烧的特征的影响。该实验使用了化学试剂，甲基油酸盐（OME，C18：1），甲基月光酸盐（LME，C12：0）以及甲基棕榈酸酯（PME，C16：0）和OME或LME作为碱燃料的混合物。所获得的值得注意的结果如下：（1）散装模量是通过在低燃油压力条件下（> 40MPA）的声速测量来确定的，结果表明OME的批量模量比天然气油高约7％。通过测量注射管的开始和注射开始之间的时间差来检查注射的延迟。使用OME和LME的注射延迟比普通的气体油短。（2）发动机实验是用源自未使用的菜籽油，大豆油和棕榈油的生物柴油燃料进行的。这阐明了三种原材料的发动机性能，燃烧特性和排放的影响。与气体油相比，名望燃料在高载荷下显示出相似的制动热效率，并且在整个负载条件下，烟雾密度显着降低。当PME与LME或OME混合时，点火特性大大改善。（3）使用悬挂的液滴燃烧技术，使用高速摄像机拍摄的图像分析了名望液滴的燃烧特性。已经发现，当PME与OME混合时，点火延迟缩短并且燃烧速度会增加。在燃烧过程中，将形成的烟灰收集在玻璃纤维过滤器上，并通过微平衡称重质量。结果表明，用OME的烟灰形成速率（定义为烟灰与液滴的质量比）低于气体油滴的15％。
