Why the filter must be changed？

I’ve seen a lot of talk about this kind of thing lately. But many people don’t know how to choose, PAWELSON® filter manufacturers will explain to you today:

The oil filter is located in the engine lubrication system. Its upstream is the oil pump, and downstream is the various parts in the engine that need to be lubricated. Its function is to filter out harmful impurities in the oil from the oil pan, and supply the crankshaft, connecting rod, camshaft, supercharger, piston ring and other moving pairs with clean oil, which plays the role of lubrication, cooling and cleaning. Extend the life of these components. The air filter is mainly responsible for removing particulate impurities from the air. When the piston machine (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed.

PAWELSON®, a Chinese filter manufacturer, said that the air filter consists of a filter element and a housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. 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 filter the iron oxide contained in the fuel. The structure of the fuel filter is composed of an aluminum shell and a bracket with stainless steel inside. The bracket is equipped with a high-efficiency filter paper. , to increase the flow area. EFI filters cannot be used with carburetor filters. Because 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.

According to PAWELSON®, there are various impurities in general gasoline, and certain dirt will be deposited in the fuel tank after long-term use. The above reasons will affect the quality of gasoline. The function of the gasoline grid is to filter the above impurities. The gasoline in the fuel tank reaches the combustion chamber of the engine through the filtering of the gasoline grid, and its cleanness and purity can be effectively guaranteed.
