  • Publication number: 20180031180
    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.

  • Publication number: 20170120745
    Abstract: A fuel filling apparatus and method for a bi-fuel vehicle using both gasoline and liquefied petroleum gas (LPG) as a fuel are provided to. The fuel filling apparatus and method are capable of temporarily burning a portion of LPG fuel after collecting the fuel portion, using a gasoline fuel tank and a canister, when the internal pressure of an 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.
