Fuel filter 26320-2S000 for Hyundai

Function

Protecting engine components: It can filter out harmful particles and water in the engine fuel system, preventing iron oxide, dust, and other solid impurities from entering, protecting the oil pump, oil nozzle, cylinder liner, piston rings, and other components, reducing mechanical wear, and avoiding performance issues due to clogging.

Ensuring fuel purity: It makes the fuel entering the engine for combustion cleaner, allowing for more complete combustion, reducing carbon deposits, improving engine power output and stability, and also helping to reduce harmful substances in exhaust emissions.

Working principle

Gasoline filter: For carburetor-type gasoline engines, the gasoline output from the fuel pump enters the housing through the oil pipe, is filtered through the filter element, enters the filter element cavity, and then is delivered to the carburetor through the outlet pipe. For electronic fuel injection engines, the gasoline is drawn from the fuel tank by the fuel pump, pressurized to approximately 0.3 MPa, and then impurities and water are removed by the filter before being sent to the fuel distribution pipe, then injected into the intake pipe by the fuel injector, with excess fuel being returned to the fuel tank.

Diesel filter: Diesel fuel first enters the diesel water separator, where water is separated by sedimentation and filtration, then it passes through a diesel fine filter to remove small particles, providing clean diesel fuel for the engine.

Structural components

Housing: Usually made of aluminum alloy, iron, or plastic, it protects the internal filter element and other components. The material and shape of the housing vary depending on the type of fuel filter.

Filter element: This is the core component of the fuel filter, mainly used to filter impurities from the fuel. Common filter element materials include paper, chemical fiber, ceramic, and stainless steel. Filter elements of different materials differ in filtration efficiency and service life.

Inlet and outlet: These are used to connect fuel lines, allowing fuel to smoothly enter the filter for filtration and then delivering the filtered fuel to the engine or other components.

Other components: These may include sealing gaskets, springs, dust covers, and sedimentation cups. Sealing gaskets prevent fuel leaks, springs secure the filter element, dust covers prevent dust and other impurities from entering the filter, and sedimentation cups collect water and heavier impurities from the fuel.
