This work investigates the experimental study to examine the operation characteristics of a neat neem oil methyl ester (BD100) along with silver oxide nano-particles as a metal-based additive in various mass fractions. Silver oxide nano-particle is mixed into 100% of BD100 at 5 and 10 ppm. The experimental investigation on diesel engine reveals that the addition of silver oxide nano-particles to BD100 resulted in enhancement of brake thermal efficiency (BTE) with a reduction in brake specific fuel consumption (BSFC). The tested emission parameters such as CO, HC, NOx, and smoke were decreased by 12.22, 10.89, 4.24, and 6.61% for BD100+ AgO (5 ppm) and 16.47, 14.21, 6.66, and 8.34% for BD100 respectively when compared to BD100. Overall, improvement in ignition characteristics of the engine was finer by adding 5 and 10 ppm of silver oxide nano-particle to BD100 on account of the enhanced surface area to volume ratio.
本工作研究了实验研究，以检查纯印楝油甲酯（BD100）与氧化银纳米粒子作为金属基添加剂在不同质量分数下的运行特性。氧化银纳米粒子以 5 和 10 ppm 的比例混合到 100%的 BD100 中。在柴油机上的实验研究表明，将氧化银纳米粒子添加到 BD100 中，可提高制动热效率（BTE），同时降低制动比油耗（BSFC）。与 BD100 相比，BD100+AgO（5 ppm）的 CO、HC、NOx 和烟度等测试排放参数分别降低了 12.22%、10.89%、4.24%和 6.61%，BD100 分别降低了 16.47%、14.21%、6.66%和 8.34%。总的来说，由于氧化银纳米粒子的表面积与体积比的增加，向 BD100 中添加 5 和 10 ppm 的氧化银纳米粒子可改善发动机的点火特性。
