The application range of fuel filters is very wide, and we definitely need to know its characteristics before using it so that we can better apply it.

The application range of fuel filters is very wide, and we definitely need to know its characteristics before using it so that we can better apply it.If you are interested in this topic, then let's take a look together, hoping to bring help to some relevant people.

The role of fuel filters is to prevent particulate matter, moisture and impurities in the fuel, and to ensure that the precision components of the fuel system are protected from wear and other damage.In fact, when working, his principle is to connect in series on the pipeline between the fuel pump and the fuel inlet of the throttle body.The role of the fuel filter is to remove iron oxide, dust and other solid impurities contained in the fuel, and prevent clogging of the fuel system (especially the fuel injector).In this case, mechanical wear can naturally be reduced, the engine operation can be stable, and the reliability can be improved.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 carburetors.Since the EFI filter often undergoes a fuel pressure of 200-300KPA, its compressive strength is generally required to reach more than 500KPA at this time, 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 engine oil, and there are two types: replaceable and rotary-mounted.However, its working pressure and oil temperature resistance requirements are much lower than that of the oil filter, but its filtration efficiency is much higher than that of the oil filter.Most of the filter elements are made of filter paper, but some are made of felt or polymer materials.The important role in use is to separate the moisture in diesel.The presence of water is extremely harmful to the engine oil supply system, corrosion, wear, clogging and even deterioration of the diesel combustion process.Due to the high sulfur content in China, it will even react with water to generate sulfuric acid during combustion, corroding engine parts.Of course, some traditional methods of water removal are mainly sedimentation, through the funnel structure.Engines with emissions above National Level III have higher requirements for water separation and high requirements, and high-performance filter media are required.Therefore, fuel filters are used to filter fine particles in diesel.Diesel engines that emit more than national three 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, developed and produced a variety of filters, as many as hundreds of varieties and specifications of high-quality sub-series products.
