Fuel filters play a vital role in today's modern, tolerant engine fuel systems. Unfiltered fuel may contain various pollutants, such as paint chips and dirt that hit the fuel tank during refueling, or steel The rust caused by the moisture in the tank, if these substances are not removed before the fuel enters the system, due to the wear effect of the particles on the high-precision components used in modern injection systems, they can cause rapid wear and failure of fuel pumps and injectors. Fuel filters also improve performance because there are fewer pollutants in the fuel and it can be burned more efficiently.

fuel filter? Let's take a look.

The function of the fuel filter is to filter out harmful particles and water in the engine gas system, protect the oil pump nozzle, cylinder liner and piston ring, reduce wear and avoid clogging. The fuel filter removes solid impurities such as iron oxide and dust contained in the fuel, prevents the fuel management system from clogging (especially the fuel injector), reduces the wear and tear of construction machinery and equipment, ensures the stable development and operation of the engine, and improves product reliability. There are three types of fuel filters: diesel filters, gasoline filters and natural gas filters. The fuel filter is a consumable. During the management process of the vehicle, it needs to be replaced and maintained regularly, otherwise it will not play an important role in qualified protection.

fuel filter has been filtered. Early gasoline filter elements were sheet metal gap type, metal wire mesh type, nylon cloth type, porous ceramic type, etc.; diesel filter elements were cylindrical felt type, nylon cloth type, cotton yarn type, etc. These filter elements have good control performance and long service life. However, the general development has the disadvantages of low filtration efficiency, complex structure, high cost, and inconvenient maintenance work, and they have been gradually eliminated.

At present, both gasoline filters and diesel filters generally use microporous paper filter elements, which are treated with phenolic resin and made into a folding tube type, which has good passing performance, high filtration efficiency, simple structure, and low cost., Easy maintenance and other advantages.

Now, most engines are equipped with disposable non-removable paper filter fuel filters. The replacement cycle is generally 10000km, and the mandatory replacement cycle is 30000km. If the fuel impurity content is large, The driving distance should be shortened accordingly. In addition, the filter has in and out of the oil port arrow mark, do not install reverse when replacing, if not carefully turned over, even in the overturned state of work for a short time, must be replaced.

China Filter has gone through more than 30 years. Bengbu initiated the establishment of national testing standards in Bengbu in the 1980 s, thus promoting the rapid rise of the entire industry. In particular, the Wenzhou model has shone brilliantly, from automobile accessories to automobile parts. There has been a qualitative leap from the outside to the inside of the car. However, the fuel filter, that is, the gasoline filter, has not been paid attention to. It is changed frequently in 4 filters, A product that is easy to be ignored, the gasoline filter has been lurking for many years. With the acceleration of the speed of the car, the rapid heating of oil prices, the transformation of the environment, the environmental protection of skills, and the reduction of carbon emissions, the gasoline filter has been changed from external to built-in, from carburetor The change to electronic injection, the built-in gasoline filter has become a trend.
