摘要 本研究重点研究氧化铈 (CeO2) 纳米粒子的粒径对使用纯印楝生物柴油 (NBD100) 的四冲程单缸水冷柴油发动机排放特性的影响。印楝油被酯交换成生物柴油并用于这项工作。 NBD100中包含有10nm和20nm各种粒径的氧化铈作为添加剂，称为NBDCeO210和NBDCeO220。实验结果证明，燃料的所有化学和物理性能均符合ASTM标准。在 3.5 bar BMEP 下，NBD100 的 CO 和 HC 排放量比柴油低 4.3% 和 4.7%。 CeO2纳米颗粒使NBDCeO220比NBD100进一步减少了CO和HC排放4.2%和3.6%。 NBD100 的 NOX 排放量在 3.5 bar BMEP 下高出 5.6%。与NBD100相比，使用NBDCeO210和NBDCeO220作为燃料时，尾气NOx排放量分别降低了2.7%和3.6%。此外，使用 NBD100 进行燃油时，尾气排放量降低了 1.7%。
ABSTRACT This study focuses on the effect of particle size of cerium oxide (CeO2) nanoparticle on the emissions characteristics of four-stroke, single cylinder water-cooled diesel engine fueled with neat neem biodiesel (NBD100). Neem oil is transesterified into biodiesel and employed in this work. Cerium oxide as an additive in various particle-size of 10 nm and 20nm is included to NBD100 and termed as NBDCeO210 and NBDCeO220. The experimental result proved that all the chemical and physical properties of fuels are in sequence with ASTM standards. The CO and HC emissions are 4.3% and 4.7% lower for NBD100 than diesel at 3.5 bar BMEP. CeO2 nanoparticle further reduces CO and HC emissions 4.2% and 3.6% correspondingly for NBDCeO220 than NBD100. The degree of NOX emission in NBD100 is 5.6% higher at 3.5 bar BMEP. When compared to NBD100, tailpipe NOx emission was found to be 2.7% and 3.6% lower when fueled with NBDCeO210 and NBDCeO220. In addition, the tailpipe smoke emission was found to be 1.7% lower when fueled with NBD100.
