Fuel filter's working principle:

To guarantee the cleanliness of oil, extending the life of diesel fuel filter, fuel delivery systems for motor vehicles generally use two-stage filter, that is, by using precipitation with an oil-water separator (strain) and diesel fuel filter (thin). When engine, diesel by diesel after coarse filtration for precipitation, diesel fuel filter-paper filter level filter for oil, filter filter material produced by our factory adopts the imported filter paper, high filtration efficiency, small flow resistance and long service life. It is an ideal choice for fuel supply system.

Diesel fuel filter's application:

Fuel system parts for diesel oil water corrosion of rusty and damaged by impurities, diesel fuel filter diesel engine fuel supply system can effectively filter out harmful particles and diesel with impurities such as moisture, improve the quality of diesel to protect the pump fuel injectors, cylinder liner and piston ring, reduce the abrasion, avoid blocking, thus protecting the engine performance and service life.

Fuel filter's struction is the same as oil filters,divided into lube and Interchangeable. But its work under pressure and oil temperature requirements are much lower than the oil filter, the filter efficiency requirements are much higher than the oil filter. Diesel fuel filter’s filter element is filter paper, also use felt or polymer material. Diesel fuel filtr can be divided into fuel-water separator diesel, diesel fuel fine filter. The important feature of fuel water separator is to separate water in the fuel. Water for fuel system of diesel engine great harm, rust, wear, stuck or even worsen the diesel combustion process. Because of higher sulphur content of diesel fuel, combustion occurs, even water and produce sulfuric acid corrosion of engine parts. Traditional methods of water main is settling, through the funnel structure. Engine on water separation more than three emissions put forward higher requirements, high demand requires a high-performance filtration media. Diesel fuel fine filter is used to filter small particles in diesel, third-year junior high emissions of diesel engines above deals mainly with 3-5 micron particle filtration efficiency. Diesel polishing filter is used to filter small particles in diesel, in the country more than three diesel engine emissions is mainly targeted at 3-5 micron particle filtration efficiency.
Currently high-performance diesel fuel filter (meeting three more emission of electronic controlled diesel engine), including fine filter and fuel water separator, is monopolized by foreign brand,such as BOSCH, Mann-Hummel , Parker, Fleetguard and so on,Internal brand is Difite.
