摘要 |
A liquid propane fuel storage and delivery system for a vehicle engine with a fluid handling component module removably top-mounted on an appropriate vehicle-mounted pressurized liquid propane fuel storage tank. The module includes: (1) a fuel tank 80% stop-fill subsystem that automatically opens and closes the tank fill port to control tank fuel fill; (2) a hydrostatic back-check valve to prevent reverse fuel flow from the tank to atmosphere via the fill port; (3) an excess fuel bypass return check valve that maintains a predetermined amount of pressure in the fuel line as required to achieve acceptable engine performance; (4) a return check bypass valve that bypasses the return check valve to allow an extra amount of vapor-purging liquid fuel to be flushed through the system and returned to the tank through the fill solenoid prior to engine start-up; (5) an excess flow valve to limit fuel flow to atmosphere in case of a severed fuel line; (6) a supply solenoid valve assembly that prevents fuel flow to the engine if the solenoid is not energized; (7) a supply line over-pressure check valve to prevent a pump outlet line from being overstressed due to pressure build up; (8) a tank pressure relief valve; (9) a tank drain valve; (10) a "leak-free" electrical coupling; and (11) a fuel pod assembly housing one or two fuel pumps pumping either in parallel or series flow. |
