Fuel filters function as a defense against contaminated fuel. Their function is to deal with minor contamination that escapes preventive measures to keep the fuel tank clean. A diesel engine may have a primary and a secondary fuel filter. A primary filter is the main defense against water and larger particles in the fuel supply, but it does not guard against microscopic particles of dirt and water. These are filtered out by the secondary filter.

This provides for priming and positive pressure in the injection pump. In common with all diesel fuel systems, a fuel filter and water trap is used to ensure that only very clean fuel is delivered to the pump. Return pipes are used for excess fuel leakage, for purging the pump and for lubrication of the injectors.

Understanding the impact of different biodiesel blends on fuel supply systems as well as the performance of the engine is crucial. The fuel filter is a key part of keeping the fuel clean and free of contaminants. When biofuels are used, fuel filters can become clogged more quickly than when pure petroleum fuels are used [4]. Because of its high water content and hydrophilicity, biodiesel considerably lowers filter media tensile strength [5]. Biodiesel’s filter-clogging tendency is proportional to its moisture content. A biodiesel fuel flow issue arises when there are too many saturated fatty acids in the fuel [6]. Because it is more viscous than diesel (30% more), Ceiba pentandra biodiesel displays poorer flow characteristics in the fuel supply system and the filter. To improve filtration efficiency, a smaller pore size is essential. As more particles are filtered and accumulated in the filter, however, the pressure drop increases [5]. The deposition of particles is proportional to the pressure drop they cause [7].
