PURPOSE: A fuel supplying structure of an LPG vehicle is provided to enhance a fuel consumption ratio and to reduce an exhaust gas by maintaining stably an idle driving at the LPG vehicle. CONSTITUTION: A vaporizer(10) is operated to decompress a high pressure fuel induced from a bombe, to mix the decompressed fuel with air at a mixer(20), and to supply the mixed fuel to a combustion chamber. The vaporizer(10) is provided with a first chamber(11), a second chamber(12) and a chamber(13) for controlling a pressure of the second chamber. A solenoid valve(30) is installed at the chamber(13) to control the pressure induced to the chamber(13). A connecting pipe(31) is connected to the solenoid valve(30) in order to induce an atmosphere together with air flowing between a throttle valve(21) and a venturi(22). The pressure of the second chamber(12) of the vaporizer(10) is varied according to an opening angle of the throttle valve(21). An electronic control unit(40) checks a variation of the opening angle of the throttle valve(21) and if the engine is an idle state, the solenoid valve(30) is operated so that the pressure induced from the vaporizer(10) to the chamber(13) is higher than an atmospheric pressure. |
