Diesel Generator Tech

Here, I am willing to share the basic working principle of diesel engine fuel filter. The purpose of any diesel  fuel filter is to remove foreign particles as well as water. The use of a suitable filtration system on diesel engines is a must to avoid damage to closely fitted injection pump and injector components.  Filter's ability varies between the type and manufacturer. On diesel engines primary and secondary filters are used. The primary filter is capable of removing dirt particles down to 30 microns and the secondary filter between 10 to 12 microns. Secondary filters are available between 3 and 5 microns, which are used in severe service operations. The primary filter is usually located between the tank and the supply pump, the FWS is one type of the primary filters. The secondary filter between the supply pump and the injection pump. Diesel fuel filter is referred to as full-flow filter, because all the fuel must pass through it before reaching the injection ...
