  • Patent number: 10794537
    Abstract: A system for filling an LPG vehicle with LPG using an auxiliary bombe is provided. The system may be configured for easily filling a main bombe with LPG even in the hot season (summertime) or the like during which the outside temperature rapidly rises, by using an auxiliary bombe in addition to using the main bombe. The system may also be capable of always smoothly refilling the main bombe with LPG by moving a portion of the LPG in the main bombe to the auxiliary bombe, when the pressure in the main bombe is higher than the LPG filling pressure of a filling gun in the hot season during which the outside temperature rapidly rises, so that the pressure in the main bombe becomes lower than the filling pressure.

  • Patent number: 10343515
    Abstract: A fuel filling apparatus and method for a bi-fuel vehicle using both gasoline and liquefied petroleum gas (LPG) as fuel are provided to an LPG fuel tank. The fuel filling apparatus and method are capable of temporarily burning a portion of LPG fuel after collecting a fuel portion, using a gasoline fuel tank and a canister, when the internal pressure of the LPG fuel tank in the bi-fuel vehicle is equal to or greater than an LPG filling pressure of a filling gun. Additionally, the internal pressure of the LPG fuel tank is decreased to a level below the LPG filling pressure of the filling gun, thereby achieving smoother LPG fuel filling of the LPG fuel tank by the filling gun.

  • Patent number: 9957930
    Abstract: An apparatus and a method for charging an LPG fuel vehicle are provided to charge a LPG tank with LPG fuel by decreasing part of pressure in the LPG tank when pressure in the LPG tank, which stores the LPG fuel, is greater than charging pressure. That is, pressure in the LPG tank is decreased to be equal to or lower than charging pressure of a charger and the LPG tank with LPG fuel is charged more smoothly from the charger, by capturing part of the LPG fuel in the LPG tank and allowing the LPG fuel to be combusted in the engine when pressure in the LPG tank of the vehicle is greater than LPG charging pressure of the charger.
