Crude oil production and its resources have been restricted today due to its depletion and consumption rate. Biodiesel involves less production cost, environmentally friendly, renewable, non-toxic and biodegradable. In this examination, a novel source likes Cassia javanica has been used as a feedstock for biodiesel utilizing the transesterification process. The impacts in biodiesel on exhaust gas emissions vary depending on the type of biodiesel and petrodiesel. Blends of biodiesel up to 20% mixed with petrodiesel fuels have been be used in all diesel engines and is more easily storage and distribution tools. The purpose of the current study investigates the analysis of biodiesel and their blends with diesel oil in four-stroke ICE applications like unburned hydrocarbons, sulfates, particulate matter, polycyclic aromatic hydrocarbon, carbon monoxide, and nitrated aromatic hydrocarbons. It ended that Cassia javanica methyl ester biodiesel blend (B20) with the addition of SiO₂ nanoparticles exhibits a better engine performance and emission reduced compared to fossil fuels. Cassia javanica methyl ester can use directly in diesel engines without requiring extensive engine changes.

决明子爪哇生物柴油与SiO2纳米颗粒共混用于IC发动机应用

由于原油的消耗和消耗率的增加，今天的原油生产及其资源受到限制。生物柴油的生产成本更低，环境友好，可再生，无毒且可生物降解。在这次考试中，有像Cassia javanica这样的新颖消息来源利用酯交换法已被用作生物柴油的原料。生物柴油对废气排放的影响因生物柴油和石油柴油的类型而异。所有柴油发动机都使用了混合比例高达20％的生物柴油与石油柴油的混合物，并且更容易存储和分配工具。本研究的目的是研究四冲程ICE应用中的生物柴油及其与柴油的混合物的分析，例如未燃烧的碳氢化合物，硫酸盐，颗粒物，多环芳烃，一氧化碳和硝化芳烃。结果表明，添加了SiO _2的决明子爪哇甲基酯生物柴油混合物（B20）与化石燃料相比，纳米颗粒具有更好的发动机性能并减少了排放。决明子爪哇甲酯可以直接用于柴油发动机，而无需大量更换发动机。
