Recently, many netizens have asked what is the working principle and characteristics of the oil filter?I want to know, so today the fuel-water separator manufacturer will share with you, what are the characteristics and working principles of the fuel filter?Let's take a look:

1. Classification of fuel filters

There are three types: diesel, gasoline and natural gas.Its role is to filter out harmful particles and moisture in the engine gas system, thereby protecting the oil pump nozzle, cylinder liner, piston ring, etc.Reduce wear and avoid clogging.

There are two types of gasoline filters: carburetor type and EFI type.For gasoline engines using carburetors, it is located on the oil inlet side of the oil pump and the working pressure is low.Generally use nylon sleeves.For EFI engines, it is located on the outlet side of the oil pump and has a high working pressure. A metal housing is usually used.Filter paper is mostly used for filter elements, and nylon cloth and polymer materials are also used.

The fuel-water separator manufacturer said that 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 nozzle).Reduce mechanical wear, ensure stable engine operation, and improve reliability.

2. The working principle of the fuel filter

Generally, there are various impurities in gasoline, and a certain amount of dirt will be deposited in the fuel tank after a long time.The above reasons will affect the quality of gasoline.The role of the gasoline grid is to filter the above-mentioned impurities. The gasoline in the fuel tank is filtered through the gasoline grid and reaches the combustion chamber of the engine, so that its clean purity can be effectively guaranteed.

Third, the performance characteristics of the fuel filter

If the filter is installed in the fuel line, it is called an external filter.On the contrary, internal filters refer to filters installed inside fuel pumps and fuel tanks.Among them, the fuel tank filter or its protective sleeve is usually considered a maintenance-free part.

The fuel filters of many imported vehicles are connected by drum-shaped tubes.In order to ensure the reliability of the connection and sealing, the same gasket must not be reused.In addition, even if a brand new gasket is used, the tightness of the connection and fastening must be checked.When the fuel system needs to replace the “O” ring, make sure that the specifications and models are correct, and check whether the elasticity and hardness of the ring are appropriate.

According to the fuel-water separator manufacturer, the non-loop fuel system has only one internal filter (in the fuel tank). Although this kind of all-in-one pump, filter, and delivery unit is expensive, when fuel delivery is blocked or engine performance decreases as a result, it must also be properly maintained and maintained in time.At the same time, it is also necessary to check the faults in all fuel pipelines and the cracking and crimping conditions at the hose clamps.
