Abstract:
Various methods and systems are provided for a pressure relief valve of a fuel system. In one example, a valve includes a first chamber in fluid communication with a first fuel line, a second chamber in fluid communication with a second fuel line and in fluid communication with a fuel storage tank, a piston separating the first chamber from the second chamber, and a needle coupled to the piston and controlling a flow passage between the second fuel line and the second chamber, where the piston and needle are sized such that a force applied on the piston by the first chamber parallel to an axis of movement of the piston maintains the needle in a closed position when the first fuel line flows fuel at a first pressure and the second fuel line flows fuel at a second pressure, the second pressure greater than the first pressure.

Claim (Index 15):
The system of  claim 14 , wherein, during priming prior to engine cranking, the high pressure fuel pump is deactivated and the low pressure fuel pump is operated to supply fuel at a first pressure to the pressure relief valve, the fuel at the first pressure applying a force to close the pressure relief valve, wherein during engine cranking, the low pressure fuel pump is operated to supply fuel at the first pressure and the high pressure fuel pump is activated to supply fuel at a second pressure to the pressure relief valve, wherein during engine operation, the low pressure fuel pump is operated to supply fuel at the first pressure and the high pressure fuel pump is operated to supply fuel at a third pressure, the second pressure and third pressure each higher than the first pressure and wherein the fuel supplied at the first pressure is supplied at a pressure in a range of 5-7 bar, the fuel supplied at the second pressure is supplied at a pressure in a range of 700-1000 bar, and the fuel supplied at the third pressure is supplied at a pressure in a range of 2200-2750 bar.
