PROBLEM TO BE SOLVED: To stably obtain atomization action of a liquid fuel. SOLUTION: A throttle portion 12 is provided in a fuel supplying pipe 7 extending from a fuel tank 8 to a pump 6, and a mixed fluid supplying pipe 13 extending from a mixed fluid tank 9 is opened into the throttle portion 12. When liquid fuel flows through the throttle portion 12, a mixed fluid is led into the fuel supplying pipe 7 by decompression action occurring around the throttle portion to form a mixture. The mixture is pressurized by the pump 6, and heated up by a heater 43. Consequently, the mixed fluid included in the mixture is made to be in a super critical state. The liquid fuel and the mixture of the mixed fluid in the super critical state are successively jetted from an injection valve 2. |
