Abstract
A fuel filter is configured to filter fuel for an internal combustion engine and is associated with an electromagnetic wave generator configured to emit high frequency electromagnetic waves operable on the fuel to heat and thereby melt wax crystals suspended in the fuel.
Claims20
A fuel filter assembly for filtering fuel for an internal combustion engine comprising;
- an electromagnetic wave generator positioned in a fuel flow path and configured to emit high frequency electromagnetic waves that are operable on the fuel to heat and thereby dissolve wax crystals suspended in the fuel.
A fuel system for an internal combustion engine comprising;
- a fuel reservoir;
- a fuel pump configured to withdraw fuel from the fuel reservoir through a fuel conduit fluidly communicating the reservoir and the fuel pump;
- a fuel filter in fluid communication with the fuel conduit comprising a fuel filter manifold having a fuel inlet and a fuel outlet for receipt of fuel from the fuel conduit and return of fuel to the fuel conduit;
- and
- an electromagnetic wave generator associated with the fuel filter manifold configured to emit high frequency electromagnetic waves directly operable on the fuel to heat and thereby dissolve wax crystals suspended in the fuel.
