Fuel filter 1111402XED96 for Great Wall Cannon

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 nozzle, cylinder liner, piston rings, etc., reducing mechanical wear, and avoiding performance issues due to blockage.

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 through the fuel line, is filtered through the filter element, enters the filter element cavity, and is then delivered to the carburetor via the outlet pipe. For electronic fuel injection engines, gasoline is drawn from the fuel tank by the fuel pump and pressurized to approximately 0.3 MPa before passing through the filter to remove impurities and water, then sent to the fuel distribution pipe, and then injected into the intake pipe by the injector. Excess fuel is returned to the fuel tank via the return pipe.

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

Structural components

Housing: Usually made of aluminum alloy, iron, or plastic, protecting the internal filter element and other components. Different types of fuel filters have different housing materials and shapes.

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. Different materials have differences in filtration efficiency and service life.

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

Other components: May also 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.
