摘要： PROBLEM TO BE SOLVED: To enhance reliability and durability of a fuel injection valve. SOLUTION: Mixed fuel is formed of which a fluid to be mixed fed from a tank for the fluid to be mixed is mixed in liquid fuel fed from a fuel tank and the fluid to be mixed is not in a supercritical state. The mixed fuel is fed to the fuel injection valve 2 so that a pressure of the mixed fuel in the fuel injection valve 2 is higher than a critical pressure of the fluid to be mixed. A fin 19 extended inside a combustion chamber 11 is formed in a tip of the fuel injection valve 2. The fin 19 is heated by combustion gas or flame so that a temperature of the mixed fuel inside the fuel injection valve 2 tip becomes higher than a critical temperature of the fluid to be mixed, and by this, the fluid to be mixed in the mixed fuel in the fuel injection valve 2 becomes a supercritical state. Then the mixed fuel is injected from the fuel injection valve.
