摘要： A fuel-filling system of an LPG vehicle is provided. LPG remaining in an LPG bombe is forcibly fed to a fuel injection pipe using a fuel pump and is used to pressurize new LPG, which is injected into the fuel injection pipe, toward the LPG bombe. Thus, the LPG bombe is refilled with new LPG despite warmer weather conditions.

摘要： 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.

摘要： A returnless fuel supply system applicable to an LPG vehicle is provided. The system supplies LPG fuel from an LPG bombe to an engine at a predetermined pressure or greater and prevents the generation of vapor in the LPG fuel, thereby eliminating a need to return a portion of the LPG fuel supplied to the engine to the LPG bombe. Through the application of the returnless fuel supply system that does not return the high temperature fuel to the LPG bombe, the cause of the internal pressure increase in the LPG bombe is eliminated, and thus efficient refueling of LPG bombe with LPG fuel is achieved.

摘要： A controller of a fuel system for a vehicle is provided in which heat is dissipated outside from a printed circuit board to cool the controller. The dissipated heat is utilized to maximize the efficiency of the purge operation using a canister by waste heat. The controller is integrated with an air filter for removing foreign substances from air to be suctioned into a canister, and is configured to realize heat exchange between air passing through the air filter and a motor driver.
