The Main Performance and Working Principle of Fuel Filters

Ⅰ. Evaluation of the fuel filter's primary functions


1. What is the purpose of a fuel filter?


The purpose of the fuel filter is to remove iron oxide, dust, and other solid pollutants from the fuel, avoid obstruction of the fuel system (particularly the nozzles), decrease mechanical wear and tear, and increase engine dependability. The fuel burner is made out of an aluminium casing and a stainless steel bracket on the interior. A high-efficiency filter paper assembly is installed in the holder. To maximize the circulation area, the filter paper is daisy-shaped.


The EFI filter and the carburettor filter such as the hyundai i20 air filter cannot be shared. This is due to the fact that EFI filters are typically exposed to fuel pressures of 200-300 kPa. As a result, the filter's pressure strength must normally be 500 kPa or more, and the carburettor filter cannot match these criteria.


2. The fuel filter's performance


(1) Maintain high performance conditions:

a. High filtration performance (cleaning efficiency);

b. Low oil resistance;

c. Long service life (storage for large amounts of impurities);


(2) Reliability and rationality quality conditions:

a. High pressure resistance, high vibration resistance, high durability, no oil leakage;

b. Low temperature resistance, high temperature resistance, high quality filter paper, adhesive, and rubber will not separate.

c. It is simple and light to use.


Ⅱ. The basis of operation of a gasoline filter


1. The diesel fuel filter's working principle


The diesel fuel pumped by the fuel delivery pump enters the shell by the inlet pipe interface, then passes through the filter core to the inner chamber of the filter element, and finally passes through the outlet pipe interface to the fuel injection pump. To accomplish the effect of filtering diesel fuel, mechanical impurities and particles in the diesel fuel are filtered out, and water is deposited in the casing. The filter can obtain the greatest performance after 5000 kilometers of regular operation of the diesel engine. The filter must be updated on a regular basis as the amount of deposited water and filtered contaminants increases, with the replacement period varying based on the actual grade of diesel utilized. Diesel filters should not be used for more than 10,000 kilometers under typical circumstances.


A drain plug is built into the bottom of certain diesel filters to help them last longer. The stopper can be unscrewed after a period of time to remove the precipitated water from the filter.


2. The principle of operation of the petrol filter


The petrol pumped by the oil delivery pump enters the housing by the input pipe interface, then passes through the filter core to the inner chamber of the filter element, and finally passes through the exit pipe interface to the carburetor. To produce the effect of filtering petrol, mechanical imperfections and dust in the fuel are filtered out in this procedure. The filter can reach the greatest performance after 5000 kilometers of regular operation of the petrol engine. Most automotive fuel filter manufacturers suggest that the filter must be updated at regular intervals as the amount of filtered contaminants rises, which should be determined by the actual quality of the gasoline used. The fuel filter should not be used for more than 10,000 kilometers under typical circumstances.
