Biodiesel has been renowned as potential and alternative fuel for years. In order to improve the quality of the conventional fossil fuels, biodiesel, and air pollution from combustion, additives are essential to exploit. In this study, the uses of cerium oxide (CeO) nanoparticle additive for B20 fuel in a diesel engine are investigated. The CeO nanoparticles with cetyl-trimethyl ammonium bromide are doped into the B20 fuel by using ultrasonicator. The purpose of the experimental work was adopted to enhance engine combustion and reduce the emissions with an approach of CeO nanoparticle additive. The experiment was conducted on a diesel engine using different propagation of CeO nanoparticle in blended mahua methyl ester fuel such as B20 + CeO 50 ppm, B20 + CeO 100 ppm, and B20 + CeO 150 ppm. The obtained results are compared with the diesel and B20 fuels. The minor changes are obtained in B20 fuel properties due to the addition of CeO nanoparticles. The performance of brake thermal efficiency and combustion of pressure data is observed to be enhanced by the addition of a metal-based additive. The CO, HC, and smoke are decreased for B20 fuel with nanoparticles. The NO is reduced by dosing the CeO due to the oxidation of unburned CeO in the exhaust.
生物柴油多年来一直被誉为潜在的替代燃料。为了提高传统化石燃料、生物柴油和燃烧产生的空气污染的质量，添加剂是必不可少的。在这项研究中，研究了氧化铈（CeO）纳米颗粒添加剂在柴油机中对 B20 燃料的用途。采用超声仪将十六烷基三甲基溴化铵掺杂的 CeO 纳米颗粒掺入 B20 燃料中。实验工作的目的是采用 CeO 纳米颗粒添加剂来增强发动机燃烧并减少排放。该实验在一台柴油机上进行，使用不同浓度的 CeO 纳米颗粒在混合麻疯树甲酯燃料中的传播，如 B20+CeO50ppm、B20+CeO100ppm 和 B20+CeO150ppm。将得到的结果与柴油和 B20 燃料进行了比较。由于添加了 CeO 纳米颗粒，B20 燃料的性能略有变化。由于添加了金属基添加剂，制动热效率和燃烧压力数据的性能得到了提高。纳米颗粒的加入降低了 CO、HC 和烟度。由于废气中未燃烧的 CeO 的氧化，CeO 的加入降低了 NO。
