The present study aimed to investigate the performance and exhaust emission characteristics of the diesel engine when fueled with a diesel mixed with different percentages of distilled Yang oleoresin. The purpose was to search for the optimal oil proportion to be eco-friendly and minimize the carbon footprint. Varied percentage concentrations of distilled Yang oleoresin were mixed with the diesel: 20% (B20), 40% (B40), 60% (B60), 80% (B80) and 100% (B100). A single-cylinder diesel engine was used to test the performance of the diesel, and blended diesel treatments, at speeds of 2,400 rpm, 2,000 rpm, 1,600 rpm, 1,200 rpm, and 800 rpm. The results showed that all blended fuel proportions gave maximum torque at a rotational speed of 1,600 rpm. The performance between B40 and diesel was not statistically significantly different (p > .05), however, B40 had a higher average torque and CO₂ emissions than pure diesel. In addition, the smoke of B40 was greater compared with diesel (~9.09%). The NOx emissions across all mixed fuel proportions were observed to be higher compared with diesel. In conclusion, B40 mixed fuel could provide an economically viable alternative to diesel because of its similar performance, emissions, and smoke.

本研究旨在研究柴油与不同比例的蒸馏扬油树脂混合后的性能和排气排放特性。目的是寻求最佳的油比例，以实现环保并最大程度地减少碳足迹。各种浓度的蒸馏杨酸树脂树脂与柴油混合：20％（B20），40％（B40），60％（B60），80％（B80）和100％（B100）。单缸柴油发动机用于测试柴油的性能，以及混合柴油处理的速度分别为2,400 rpm，2,000 rpm，1,600 rpm，1,200 rpm和800 rpm。结果表明，所有混合燃料比例在1600 rpm的转速下均提供最大扭矩。B40和柴油之间的性能在统计上没有显着差异（p > .05），但是，B40的平均扭矩和CO ₂排放量比纯柴油更高。此外，B40的烟雾比柴油大（〜9.09％）。观察到所有混合燃料比例中的NOx排放均比柴油更高。总而言之，由于B40混合燃料的性能，排放和烟雾相似，因此它可以提供比柴油更经济的替代方案。
