How fuel filters work

The fuel filter is connected in series on the pipeline between the fuel pump and the throttle body inlet. The function of the fuel filter is to remove the iron oxide, dust and other solid impurities contained in the fuel to prevent the fuel system from being blocked (especially the fuel injector). Reduce mechanical wear, ensure stable engine operation and improve reliability. The structure of the fuel burner consists of an aluminum shell and a bracket with stainless steel inside. The bracket is equipped with a high-efficiency filter paper, which is in the shape of a chrysanthemum to increase the flow area. EFI filters cannot be used with carburetor filters.

Since the EFI filter often bears the fuel pressure of 200-300KPA, the compressive strength of the filter is generally required to reach more than 500KPA, while the carburetor filter does not need to reach such a high pressure.

Fuel filter classification

1. Diesel filter
The structure of the diesel filter is roughly the same as that of the oil filter, and there are two types: replaceable and spin-on. However, its working pressure and oil temperature resistance requirements are much lower than those of oil filters, while its filtration efficiency requirements are much higher than those of oil filters. The filter element of diesel filter mostly uses filter paper, and some also use felt or polymer material.

Diesel filters can be divided into two types:
(1), diesel water separator
The important function of the diesel water separator is to separate the water in the diesel oil. The presence of water is extremely harmful to the diesel engine fuel supply system, and corrosion, wear, and jamming will even worsen the combustion process of diesel. Engines with emissions above the National III level have higher requirements for water separation, and high requirements require the use of high-performance filter media.

(2), diesel fine filter
The diesel fine filter is used to filter the fine particles in the diesel oil. The diesel engine with emissions above the national three is mainly aimed at the filtration efficiency of 3-5 micron particles.
2. Gasoline filter
Gasoline filters are divided into carburetor type and EFI type. For gasoline engines using carburetors, the gasoline filter is located on the inlet side of the fuel pump, and the working pressure is low. Generally, nylon shells are used. The gasoline filter is located on the outlet side of the fuel transfer pump and has a high working pressure, usually with a metal casing. The filter element of the gasoline filter mostly uses filter paper, and some also use nylon cloth and polymer materials.

Because the combustion method of the gasoline engine is different from that of the diesel engine, the overall requirements are not as harsh as the diesel filter, so the price is cheap.
3. Natural gas filter
Natural gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, urban, household and other gas fields. The gas filter is an indispensable device on the pipeline for conveying the medium. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, positioning valve or other equipment to eliminate impurities in the medium and protect the normal operation of the valve and equipment. Use, reduce equipment maintenance costs.
