Apparatus and method for filling LPG vehicle with LPG

An apparatus for filling a liquefied petroleum gas (LPG) vehicle with LPG, comprising:

• an auxiliary chamber disposed in an LPG bombe of the LPG vehicle;
• an auxiliary injection line branched from a fuelling line extending to the LPG bombe from a fuel inlet port for fluidic connection of the fueling line to the auxiliary chamber, wherein the LPG is supplied into the LPG bombe through the fuelling line;
• a solenoid valve mounted in the auxiliary injection line to selectively allow or block a flow of LPG from the fueling line to the auxiliary chamber;
• a temperature sensor to detect a temperature in the bombe;
• and
• a controller to control the solenoid valve to be opened when the temperature detected by the temperature sensor is equal to or higher than a critical temperature,
• wherein the LPG flows to the auxiliary injection line through the fuelling line from a filling gun while being filled to the auxiliary chamber, when the solenoid valve is opened by the controller.
