摘要

The present invention relates to a fuel system of a bi-fuel vehicle including a fuel supply line, an engine, and a bombe, wherein LPG fuel passes the fuel supply line, and the engine and the bombe are connected to each other via a fuel return line. According to the present invention, the fuel system of a bi-fuel vehicle comprises: a 3-way valve installed in the fuel return line, moving LPG fuel to a canister connected to a fuel tank wherein LPG fuel is returned by selective opening thereof; and a return tube divaricated and formed in the fuel return line, installed to let LPG fuel pass the canister wherein LPG fuel is returned in accordance with operation of the 3-way valve, and moving LPG fuel to the fuel return line after the temperature of LPG fuel gets lower due to heat exchange when LPG fuel passes the canister.
