研究了在环境条件下使用生物柴油工业副产品油籽饼生物合成银纳米粒子。通过目视和分光光度分析银纳米颗粒（AgNP）的形成。棕色的出现表明 AgNP 的形成，这通过 UV-Vis 在 435 nm 处出现表面等离子体带得到证实。通过 FT-IR、粒度分析仪、XRD 和 FESEM 对合成的 AgNPs 进行了表征。 FESEM结果显示纳米粒子的晶粒尺寸在18-30nm范围内。在本研究中，生物合成的纳米银被用作生物柴油的添加剂，并研究了其对发动机性能的影响。在 Kirlosker 制造的 4 冲程、水冷、单缸、直喷、固定压缩比柴油机上进行了实验，以确定柴油机的排放特性和性能评价。柴油-生物柴油-AgNPs 混合物。使用超声波发生器将AgNPs以25ppm和50ppm的质量分数掺入生物柴油中，以使其适当分散并提高混合物的稳定性。结果表明，由于在生物柴油中添加了纳米银颗粒，断裂热效率显着提高，其中较低的纳米银颗粒剂量水平进一步提高了发动机的性能。因此，使用纳米颗粒混合生物柴油可以提高发动机的性能效率，并有利于进一步减少有毒气体排放方面的碳足迹。因此，纳米技术在生物燃料中的应用将有助于减少柴油消耗，从而减少原油进口，从而减轻政府外汇负担，从而有助于提振经济。
Biosynthesis of silver nanoparticles under ambient condition using oil seed cake which is a byproduct from biodiesel industry is investigated. The formation of silver nanoparticles (AgNPs) was analyzed visually and spectrophotometrically. Appearance of brownish color indicated the formation of AgNPs which was confirmed by the appearance of surface Plasmon band at 435 nm by UV-Vis. The synthesized AgNPs were characterized by FT-IR, particle size analyzer, XRD and FESEM. FESEM results revealed the grain size of nanoparticles is in the range of 18-30nm. In the present study, biosynthesized AgNPs were used as an additive for biodiesel and its influence on engine performance was studied. Experiment were carried out on Kirlosker make, 4 stroke, water cooled, single cylinder, direct injection, diesel engine at fixed compression ratio to determine emission characteristics and performance evaluation of diesel &; diesel-biodiesel–AgNPs blends. AgNPs were blended into biodiesel in the mass fraction of 25ppm and 50ppm using ultrasonicator for proper dispersion and for improving the stability of the blends. The results showed significant increase in break thermal efficiency due to addition of silver nanoparticles in biodiesel, where lower dosing level of AgNPs further improved the performance of the engine.Hence usage of nanoparticles blended biodiesel enhances the engine performance efficiency and will facilitate further reduction of carbon footprint in terms of noxious gas emissions. Therefore application of nanotechnology in biofuels will help in reduction of diesel consumption, which in turn will help in boosting the economy by reducing the import of crude oil thereby reducing the burden on government foreign exchange.
