Zusammenfassung:PROBLEM TO BE SOLVED: To materialize good startability/stability of an engine by avoiding liquid LPG fuel from mixing in the fuel supplied to the engine in a low temperature start without cost increase, in supply of LPG fuel to the engine. SOLUTION: In an LPG fuel supply method heating/vaporizing liquid LPG fuel stored in a fuel tank 1 with using heat of engine cooling water and injecting the same from an injector 5 to an intake conduit of the engine, and avoiding liquid LPG fuel from mixing in engine supply fuel by performing open close control of a shut off valve 2b provided at an upstream of a vaporizer 3A to restrict introduction quantity of LPG fuel into the vaporizer 3A in low temperature start, the restriction of introduction quantity of LPG fuel introduces LPG fuel of quantity corresponding to injector flow rate.
