PURPOSE:To increase the efficiency of fuel consumption of an internal combustion engine, by ejecting fuel from a nozzle disposed in a vaporizing container, baporizing fuel in the container, and drawing the vaporized fuel into an intake pipe at a required rate. CONSTITUTION:In feeding vaporized fuel into a fuel supply pipe 1, liquid fuel in a fuel tank 10 is at first drawn up by a pump 13. Then, the liquid fuel is sprayed, under a high pressure, upward from an injection nozzle 12 disposed near the bottom of a conical vaporizing container 8, the diameter of which is decreased toward its top, at a rate greater than the quantity into the fuel supply pipe 1 by the negative pressure. Here, the particle sizes of fuel are reduced toward the top of the container 8 and vaporization of fuel is promoted, whereas the particle sizes of fuel near the inner wall surface of the container are relatively large, so that the fuel near the inner wall surface of the container is recovered into the fuel tank 10 via revovery pipe 9. Only the vaporized fuel in the container 8 is drawn into the pipe 1 and supplied to an engine 3 through a venturi 5. |
