Diesel motors are used vastly as main sources of power in industry and transportation in modern countries. They are heavy-duty and their durability and simplicity makes them technically and economically handy. Diesel engines performance depends on clean fuel, mainly because of injection equipment and ultra-high pressure pumps. So, the most appropriate fuel conditioning equipment must be used. Polymeric filter media are usually used in diesel fuel filtration. Despite removing most of diesel impurities, they are unable to trap micron-size particulates. In addition, small water droplets coalescence is rarely possible. Electrospun Nano-fibrous Membranes (ENMs) are increasingly gaining momentum for their filtration efficiency in the last decade. Fineness and large surface area per unit volume of ENMs make them an effective method for particulate removal and purification. In this study, optimized ENMs were prepared and their filtration performance of micron-sized particulate matters and separation of water droplets from diesel fuel was investigated.
