Abstract: The present invention relates to a bi-fuel feed system. The bi-fuel system includes a gasoline supply unit pressurizing and supplying a gasoline fuel stored in a gasoline tank at a preset pressure; a liquid petroleum gas (LPG) supply unit supplying an LPG fuel stored in a bombe; a first injector directly injecting the gasoline supplied from the gasoline supply unit into a combustion chamber of an engine; a second injector injecting the LPG fuel supplied from the LPG supply unit into the intake air fed to the combustion chamber of the engine; and a control unit controlling operation of the gasoline supply unit and the LPG supply unit, and the first and second injectors based on a target RPM of the engine. Therefore, in case where the fuel injection types are different from each other, such as the direct injection type gasoline fuel supply system and the LPG fuel supply system, it is possible to exactly supply the gas fuel into the engine of the vehicle by calculating injection point and injection time of the LPG fuel based on the injector driving signal of the gasoline fuel supply system.
