  • Apparatus for reducing fuel waxing
    Patent number: 8051840
    Abstract: A fuel filter for an internal combustion engine is provided comprising a fuel conduit configured to transport fuel from a fuel tank to an internal combustion engine. A fuel filter manifold has an inlet and an outlet for fluid communication with the fuel conduit. A fuel filter housing is associated with the fuel filter manifold and is configured to receive fuel from and dispense fuel to the fuel filter manifold. A filter element is disposed within the fuel filter housing between the inlet and the outlet and is configured to filter fuel passing through the fuel filter housing. An electromagnetic transducer is associated with the fuel filter and is configured to emit high frequency waves operable on the fuel to reduce, via ultrasonic cavitation, wax crystals suspended in the fuel.
