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. 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.

Description

technical field [0001] The present invention relates to a fuel filling device and method for a dual-fuel vehicle, and more particularly, to a dual-fuel vehicle that uses gasoline and liquefied petroleum gas (LPG) as fuel to more easily refill the liquefied petroleum gas ( A fuel filling device and method for filling LPG) into an LPG fuel tank. Background technique [0002] Generally, in a dual-fuel vehicle using gasoline and liquefied petroleum gas (LPG) as fuel, a system for supplying gasoline fuel to the engine and a system for supplying LPG fuel to the engine are configured separately from each other, and therefore, gasoline fuel is performed in a separate manner. Loading and LPG fuel loading. [0003] Such as figure 1 As shown, by driving the refueling pump installed at the gas station, the drive based on the refueling pump transfers the LPG fuel from the LPG storage tank to the grease gun, and fills the LPG fuel into the LPG fuel tank of the vehicle with the help of t...
