Abstract: PROBLEM TO BE SOLVED: To improve the startability of an internal combustion engine by quickly supplying a gasified fuel into cylinders even during a cold startup.SOLUTION: The engine 10 includes a normal fuel tank 32, a gasified fuel tank 36, an in-tank injection valve 38, a gasified fuel supply valve 40, and others. An ECU 60 operates to supply the gasified fuel stored in the gasified fuel tank 36 during the operation of the engine to a surge tank 20 during the startup. When the gasified fuel is short during the startup, after a negative pressure is generated in the gasified fuel tank 36 utilizing cranking, the in-tank injection valve 38 is driven to newly generate gasified fuel. The gasified fuel is supplied to the surge tank 20, and the engine is re-started. Thereby, during the startup, the gasified fuel stored beforehand can be immediately supplied into the cylinders, and even if the gasified fuel is short, new gasified fuel can be quickly generated, and the engine can be smoothly re-started.
