Fuel Filters

Fuel filters are key components for engine performance and durability. What kind of engine, gasoline or diesel fuel filters prevent particles and water from damaging the engine? Injection systems are more susceptible to contamination: Fuel filters need to be replaced regularly to avoid major engine failures.

Filters are designed to meet user needs and to provide the highest possible filtering standards. The fuel filter offers at least twice the efficiency of 20 µm filtration accuracy, in line with the recommendations of new engine fuel systems and car manufacturers. The new engine filters offer excellent ease of use.

Duty of Fuel Filter

Fuel filters ensure trouble-free operation of the fuel to the engine. It’s a critical part of the system because today’s fuel injectors have tight-fitting parts that are easily clogged with dirt and sand. Instead of creating a completely burnt fine fuel spray, they start producing a completely flame-free current. Replacing the fuel filter keeps the injectors clean for longer, which means more power and better gas measurement.

Fuel filters remove dust and moisture from the fuel to protect the engine’s injection pump and nozzle from wear and clogging. The fuel is sent from the fuel tank to the engine by suction produced at the feed pump. The fuel pump is located in this circuit. The fuel passes through the inlet of the filter, enters the filter box and then passes through the filter medium, where foreign matter is removed.

Types and Features of Fuel Filters

Depending on how they are connected during replacement, there are two types of fuel filters: spin filters and cartridge filters. In rotatable filters, the filter medium is located in a metal box with a thread on the bottom. This type offers excellent machinability as the entire case can be replaced. In Cartridge Filters, only the filter media is replaced, thus helping to reduce the amount of waste material produced per replacement.

Depending on how the fuel circuit is configured, a main filter and a prefilter are used. The main filter is mainly responsible for the capture of fine contaminants. The negative pressure types use the suction pressure generated by the feed pump and are placed closer to the fuel tank than the feed pump. Positive pressure filters use the rise pressure from the feed pump and are located closer to the motor than the feed pump. Some vehicles may have both negative and positive pressure main filters.
