Fuel filter 26320-3N000 for Hyundai

Function

Protecting engine components: It can filter out harmful particles and water from the engine fuel system, preventing iron oxide, dust, and other solid impurities from entering, protecting the oil pump, oil nozzle, cylinder liner, piston ring, etc., reducing mechanical wear, and avoiding performance impairment 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, gasoline from the fuel pump enters the housing via the fuel line, is filtered through the filter element, enters the filter element cavity, and is then delivered to the carburetor via the outlet. For electronic fuel injection engines, gasoline is drawn from the fuel tank by the fuel pump and pressurized to approximately 0.3 MPa, then impurities and water are removed by the filter before being sent to the fuel distributor, and then injected into the intake pipe by the injector. Excess fuel is returned to the fuel tank via the return line.

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

Structural composition

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 for filtering impurities from the fuel. Common filter element materials include paper, chemical fiber, ceramic, and stainless steel. Filter elements of different materials differ in filtering efficiency and service life.

Inlet and outlet: Used to connect fuel lines, allowing fuel to enter the filter for filtering and delivering the filtered fuel to the engine or other components.

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