Abstract:     A fuel delivery system includes a fuel tank configured to receive liquid natural gas. A first conduit extends from a vapor holding portion of the fuel tank to an economizer valve. A second conduit extends from a liquid holding portion of the fuel tank to the economizer valve. Fluid coupled to the economizer valve is a vaporizer which is heated by coolant from the engine and is positioned below the fuel tank. The economizer valve selectively withdraws either liquid natural gas or vaporized natural gas from the fuel tank depending on the pressure within the vapor holding portion of the fuel tank. A delivery conduit extends from the vaporizer to the engine. A return conduit having a check valve formed therein extends from the delivery conduit to the vapor holding portion of the fuel tank for pressurizing the fuel tank.

First Claim:
Show all 19 claims
We claim:     1. A fuel system for delivering natural gas to an engine, the system comprising:
  • (a) a fuel tank configured to receive the natural gas at cryogenic temperatures, the fuel tank having a liquid holding portion and a vapor holding portion;
  • (b) a vaporizer disposed an elevational distance below the fuel tank, the vaporizer having an inlet end and an outlet end;
  • (c) a first conduit extending from the liquid holding portion of the fuel tank to the inlet end of the vaporizer;
  • (d) a second conduit extending from the outlet end of the vaporizer to the fuel tank;
  • (e) means for delivering the natural gas from the vaporizer to the engine;
  • (f) an economizer valve, fluid coupled with the first conduit; and
  • (g) a conduit extending from the vapor holding portion of the tank to the economizer valve.
