PROBLEM TO BE SOLVED: To ensure engine startability at the time of low temperature and idling stability after start-up, and ensure controllability and responsiveness. SOLUTION: A fuel supply device is provided with a liquid phase injector 25 for injection-supplying LPG fuel stored in a cylinder 17, as liquid phase fuel to an engine 1; a gas phase injector 16 for injection-supplying LPG fuel stored in the cylinder 17, as gas phase fuel to the engine 1; a fuel temperature sensor 31 and a fuel pressure sensor 32 for detecting the state of LPG fuel supplied from the cylinder 17 to the liquid phase injector 25; and an electronic control unit(ECU) 36 for controlling the respective injectors 16, 25. The ECU 36 controls the liquid phase injector 25 to supply liquid phase fuel to the engine 1 in the case of judging the state of LPG fuel detected by the respective sensors 31, 31, to be liquid phase, and controls the gas phase injector 16 to supply gas phase fuel to the engine 1 in the case of judging the state of LPG fuel to be gas phase. |
