With soaring fuel prices, engine emissions, and demand for energy security, the development of alternative fuels from renewable resources has become significant. The current work explores the filtration performance of a commercial diesel filter operated with diesel blends of raw and processed karanja oils. Three processes viz. esterification, transesterification, and degumming were performed with karanja oil, and their diesel blends (20% v/v) were tested in a continuous run filtration system. The fuel filter plays a significant role in removing the contaminants/impurities from the fuel. Hence, the pressure difference across the fuel filter was monitored at the flow rates (0.03 m³/h and 0.075 m³/h) and fuel temperatures (30°C and 70°C). Besides, the effects of weight gain and surface morphology on the filter characteristics were observed during the study. Further, the head loss factors of fuel filter under varying operating conditions were deduced from the experimental measurements. The results of different processed oil blends were compared with fossil diesel to find the suitable blend. By considering the fossil diesel as the reference case, the average pressure difference for the degummed blends was significantly lower compared to other tested blends, which highlights the importance of the degumming process. Furthermore, the tested images of filter revealed the presence of minor components such as sludge or gums on the filter surface for the fuel without the degumming process.

随着高昂的燃料价格，发动机排放和对能源安全的需求，利用可再生资源开发替代燃料已变得意义重大。当前的工作探讨了一种商业柴油滤清器的过滤性能，该滤清器使用的是原料和加工后的魔芋油的柴油混合物。三个过程，即。用魔芋油进行酯化，酯交换和脱胶，并在连续运行的过滤系统中测试其柴油混合物（20％v / v）。燃油滤清器在去除燃油中的杂质/杂质方面起着重要作用。因此，在流量（0.03 m ³ / h和0.075 m ³/ h）和燃油温度（30°C和70°C）。此外，在研究过程中还观察到了增重和表面形态对过滤器特性的影响。此外，从实验测量中得出了在变化的工况下燃油滤清器的水头损失系数。将不同加工油混合物的结果与化石柴油进行比较，以找到合适的混合物。通过将化石柴油作为参考案例，与其他测试混合物相比，脱胶混合物的平均压力差明显更低，这突出了脱胶过程的重要性。此外，过滤器的测试图像显示，在不经过脱胶过程的情况下，燃料的过滤器表面上存在微量成分，例如污泥或树胶。
