The Fuel Filter Media is connected in series between the fuel pump and the throttle body inlet port. The role of the Fuel Filter Media is to contain in the fuel in the iron oxide, dust and other solid debris removed to prevent the fuel system plug (especially the nozzle). Reduce mechanical wear, ensure stable operation of the engine, improve reliability. The structure of the fuel is composed of an aluminum shell and a stainless steel rigid bracket, which is composed of high efficiency filter paper on the bracket, and the filter paper is chrysanthemum-shaped to increase the circulation area. EFI filter can not be used with the oil filter.
As the EFI filter often withstand 200-300KPA fuel pressure, so the filter pressure strength is generally required to reach more than 500KPA, and the oil filter is not necessary to achieve such a high pressure.
Classification of Fuel Filter Medias
1, diesel filter
Diesel filter structure is roughly the same with the oil filter, there are two kinds of interchangeable and screw-mounted. But its work pressure and oil temperature requirements are much lower than the oil filter, and its filtration efficiency requirements are much higher than the oil filter. Diesel filter filter using filter paper, but also the use of blankets or polymer materials.
Diesel filter can be divided into two types:
(1), diesel water separator
Diesel water separator is an important function of separation of diesel water. The presence of water for the diesel engine fuel system is extremely harmful, corrosion, wear, Fuel Filter Media stuck and even worsen the combustion process of diesel. More than three emissions of the engine on the water separation of higher requirements, high requirements on the need to use high-performance filter media.
(2), diesel fine filter
Diesel oil filter is used to filter the small particles in diesel, the country more than three emissions of diesel engine is mainly for 3-5 micron particles filter efficiency.
2, gasoline filter
Gasoline filter with carburetor and EFI of the points, the use of carburetor gasoline engine, gasoline filter is located in the pump side of the import, the work pressure is small, Fuel Filter Media generally use nylon shell, EFI engine The petrol filter is located on the outlet side of the pump and has a high working pressure, usually with a metal housing. Gasoline filter filter using filter paper, but also the use of nylon cloth, polymer materials.
Gasoline filter As the gasoline engine combustion mode and diesel engine is different from the overall requirements as diesel filter harsh, so the price is cheap.
3, natural gas filter
Natural gas filter is widely used in metallurgy, chemical, petroleum, paper, medicine, food, mining, electricity, city, home and other gas fields. Gas filter is an indispensable device for conveying media piping, usually installed at the inlet end of a relief valve, relief valve, locating valve or other device, Fuel Filter Media to eliminate impurities in the medium to protect the valve and equipment Use, reduce equipment maintenance costs.
