fuel filter is very wide, we must know its characteristics before using it, so that we can better apply it. If you are interested in this topic, then take a look at it together, hoping to help some relevant people.

The role of the fuel filter is to prevent particulate matter, moisture and impurities in the fuel, and to ensure that the precision parts of the fuel system are protected from wear and other damage. In fact, when working, his principle is to connect the fuel pump and the throttle body in series between the pipeline. The function of the fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel to prevent the fuel system from clogging (especially the fuel injector). In this case, it can naturally reduce mechanical wear, make the engine run stably, and improve reliability. The structure of the fuel filter consists of an aluminum housing and an internal stainless steel bracket. The bracket is equipped with high-efficiency filter paper, which is chrysanthemum-shaped to increase the circulation area. Fuel filters cannot be used with carbureted oil. Since the EFI filter often bears the fuel pressure of 200-300KPA, its compressive strength is generally required to reach more than 500KPA, and the carburetor filter does not need to reach such a high pressure.

The structure of the fuel filter is roughly the same as that of the oil, and there are two types: replaceable and spin-on. But its working pressure and oil temperature resistance requirements are far lower than the oil filter, and its filtration efficiency is much higher than the oil filter. The filter element is mostly made of filter paper, and some are made of felt or polymer materials. An important role in the use of diesel oil is the separation of moisture. The existence of water is extremely harmful to the oil supply system of the engine, and corrosion, wear, blockage and even deterioration of the combustion process of diesel oil. Due to the high sulfur content in China, it will even react with water to form sulfuric acid during combustion, which will corrode engine parts. Of course, some traditional ways of removing water are mainly sedimentation, through the funnel structure. Engines with emissions above national level III have higher requirements for water separation and high requirements, requiring the use of high-performance filter media. Therefore, the fuel filter is used to filter fine particles in diesel. Diesel engines that emit more than three in the country are mainly aimed at the filtration efficiency of 3-5 micron particles. Since its establishment, the company has introduced advanced technology and key equipment at home and abroad, and developed and produced various filters, as many as hundreds of varieties and specifications of high-quality sub-series products.
