Device and method for reducing temperature of bombe using latent heat of LPG vaporization

摘要

A device for reducing the temperature of a bombe, which stores liquefied petroleum gas (LPG) fuel and may be connected to a fuel supply line for supplying the fuel to an injector, using latent heat of LPG vaporization, may include a fuel pump installed in the bombe and connected to an end of the fuel supply line for pressurizing the fuel, a cut-off valve installed in the fuel supply line for selectively cutting off fuel supply to the injector, a fuel collection line branched from the fuel supply line to the inside of the bombe for collecting the supplied fuel into the bombe when the cut-off valve may be closed, and an injection nozzle connected to the fuel collection line and injecting the fuel collected through the fuel collection line into the inside of the bombe. 4 of 4 S2 Out put standby message Indicating that P AE r - are lndic-tin tha NOW OPEN IGI "fuel filling is in preparation" 00000000 00 237 mues Close solenoid valve S4 Forcibly drive fuel pump (Absorb latent heat through relief pressure) S5 Temperature or pressure of bombe < predetermine N value?
