Abstract:
1. A device for reducing the temperature of a bombe, which stores liquefied petroleum gas (LPG) fuel and is connected to a fuel supply line for supplying the fuel to an injector, using latent heat of LPG vaporization, the device comprising: 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 placed inside the bombe to an inside of the bombe for collecting the pressurized fuel into the bombe when the cut-off valve is closed; a relief valve installed in the fuel collection line to supply the fuel at an increased pressure; an injection nozzle injecting the fuel supplied from the relief valve into the inside of the bombe to vaporize the fuel, wherein a temperature of the inside of the bombe is reduced by the vaporization of the fuel.
