Definitions

  • the fuel system illustrated in Figure 1 comprises a fuel tank 10 within which a fuel filter 12 is located.
  • the fuel filter 12 incorporates a low pressure pump arranged to supply fuel from the tank 10 at relatively low pressure to the inlet of a high pressure fuel pump 14 through a supply line 16.
  • the high pressure pump 14 is arranged to charge an accumulator or common rail 18 which communicates with and is arranged to supply fuel under pressure to a plurality of injectors 20.
  • the injectors 20 are arranged to supply fuel at appropriate times to respective cylinders of a compression ignition internal combustion engine 22.
  • the returned fuel is supplied through the nipple 62 and return pipe 64 to the valve 66.
  • the valve 66 supplies the returned fuel to the interior of the bowl 30 from where the fuel is once more drawn by the first stage of the pump 42 to the chamber 74.
  • the temperature the fuel supplied to the chamber 74 and hence to the filter element 48 is increased, thus the disadvantages associated with attempting to filter cold, relatively viscous, waxy fuel are reduced.
  • warm fuel is returned to the interior of the bowl 30, some fuel will be drawn into the bowl 30 from the tank 10 through the pre-filter member 32 in order to replace fuel which is supplied to the engine.
