This study offered a comprehensive investigation on engine performance and emission characteristics of Kirloskar make tangentially vertical (TV1) model single-cylinder direct injection diesel engine fuelled with diesel as a benchmark fuel. Steam distilled orange oil was converted into orange oil methyl ester (OME) by means of transesterification process. The physical and chemical properties of fuels were measured and conformed to ASTM biodiesel standards and compared with diesel. Likewise, the chemical compositions of the prepared biodiesel were estimated by using GC-MS analysis. OME comprises of 86.37% of (E)-3-propylidenecyclopentene (CH) in the maximum range. The presence of free fatty acids such as linoleic acid, palmitic acid and myristic acid in OME permits it to be the acceptable renewable resource for the production of biodiesel. Further, the work was progressed with the addition of oxygenated additives like ethanol and diethyl ether to OME to attain the improved fuel properties. Five and 10% volume of ethanol and diethyl ether were added to OME as oxygenated additives respectively. OME10DEE showed higher performance characteristics than diesel and OME blends. Further, a significant reduction in HC, NOx and smoke emission was noticed with OME10DEE. The present work recommended the application of OME10DEE as an alternative fuel on account of its better engine performance and emission characteristics than other fuel blends.
本研究对 Kirloskar 制造的切向垂直（TV1）模型单缸直喷柴油机的发动机性能和排放特性进行了全面研究，以柴油为基准燃料。通过酯交换过程将橙油转化为橙油甲酯（OME）。测量燃料的物理和化学性质，并符合 ASTM 生物柴油标准，并与柴油进行比较。同样，通过 GC-MS 分析估计制备的生物柴油的化学成分。OME 在最大范围内包含 86.37%的（E）-3-亚丙基环戊烯（CH）。OME 中存在游离脂肪酸，如亚油酸、棕榈酸和肉豆蔻酸，使其成为生产生物柴油的可接受的可再生资源。此外，通过添加含氧添加剂，如乙醇和乙醚，来进一步改进 OME 的燃料性能。分别向 OME 中添加 5%和 10%体积的乙醇和乙醚作为含氧添加剂。OME10DEE 表现出比柴油和 OME 混合物更高的性能特性。此外，OME10DEE 显著减少了 HC、NOx 和烟度排放。鉴于 OME10DEE 在发动机性能和排放特性方面优于其他燃料混合物，本研究建议将其用作替代燃料。
