The three major automotive filter devices are fuel filters, oil filters, and air filters.
They have their own principles in it:
1. The fuel filter string is on the line between the fuel pump and the throttle body inlet. The function of the fuel filter is to remove solid impurities such as iron oxide and dust contained in the fuel to prevent blockage of the fuel system (especially the injector), reduce mechanical wear, ensure stable operation of the engine, and improve reliability. Filter Equipment The structure of the fuel oil consists of an aluminum shell and a stainless steel bracket. The rack is equipped with a high-efficiency filter paper unit. The filter paper is daisy-shaped to increase the flow area. The EFI filter cannot be used with the carburetor filter. Because the EFI filter is often subjected to a fuel pressure of 200 to 300 kPa, the filter device generally requires a compressive strength of 500 kPa or more, and the carburetor filter does not have to achieve such a high pressure.
2. The oil filter is located in the engine lubrication system. Its upstream is the oil pump, and downstream is the parts of the engine that need lubrication. The function is to filter harmful impurities in the oil from the oil sump, and supply the lubricating oil to the motion pair such as the crankshaft, the connecting rod, the camshaft, the supercharger and the piston ring to play the role of lubrication, cooling and cleaning. Extend the life of these components.
3. The air filter is located in the engine intake system and is an assembly of one or more clean air filter components. Its main function is to filter out harmful impurities in the air that will enter the cylinder to reduce the early wear of cylinders, pistons, piston rings, valves and valve seats.
The three major categories of filter equipment are here for everyone.
