Zusammenfassung:	PROBLEM TO BE SOLVED: To provide simple constitution to perform the injection of fuel with high metering precision even during the generation of vapor. SOLUTION: An ECU 6 decides the generating state of vaporized fuel in a liquid injection injector 21 to perform injection of fuel in a liquid phase based on the detecting signals of a fuel pressure sensor 72 and a cooling water temperature sensor 75. A gas injection injector 22 to decide the generation state of vaporized fuel in a liquid injection injector 21 to effect fuel injection in a liquid phase and perform liquid injection in a gaseous phase according to the degree of the generation of vaporized fuel is caused to effect assist injection. Shortage in fuel due to injection of fuel in a gas liquid mixing state by the liquid injection injector 21 is prevented from occurring.
