Heavy Duty Diesel Filter

Product number:612630080087

Product introduction：

Diesel filters can be divided into: diesel water separator, diesel fine filter. The important function of the oil-water separator is to separate the water in the diesel. The existence of water is extremely harmful to the fuel supply system of the diesel engine. Rust, wear, and seizure will even deteriorate the combustion process of diesel. Due to the high sulfur content in Chinese diesel, it will even react with water to generate sulfuric acid to corrode engine parts when combustion occurs. The traditional way of water removal is mainly sedimentation, through the funnel structure. Engines with emissions above National III put forward higher requirements for water separation, and high requirements require the use of high-performance filter media.

Diesel fine filter is used to filter fine particles in diesel oil. Diesel engines with emissions above National III are mainly aimed at the filtration efficiency of 3-5 micron particles。

The brands that sell well include: Bosch, Manhu, Parker, Fleetguard, etc. The Chinese brands include: Daffite. And Weichai original gasoline filter.

Gasoline filters can be 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 relatively small. Generally, nylon shells are used. The gasoline filter is located on the outlet side of the fuel pump, and the working pressure is relatively high, usually with a metal casing. The filter element of the gasoline filter mostly uses filter paper, and some use nylon cloth and polymer materials.
