<p><P>PROBLEM TO BE SOLVED: To provide an evaporative fuel supply device of an internal combustion engine, efficiently increasing the quantity of evaporative fuel supplied to the internal combustion engine. <P>SOLUTION: This evaporative fuel supply device of an internal combustion engine includes: a fuel tank 2 as a fuel storing device storing fuel; a porous body 3 disposed in the fuel tank and having a liquid level lower part 3b positioned under the liquid level W of liquid fuel R stored in the fuel tank 2 and a liquid level upper part 3a positioned above the liquid level W of the liquid fuel R; and a vaporization accelerating device (evaporative fuel supply passages 4 and VSV5) for accelerating vaporization of liquid fuel R' raised from the liquid level lower part 3b to the liquid level upper part 3a of the porous body 3 and stored in the fuel tank 2. The negative pressure is introduced from a vaporization accelerating device to the vicinity of the liquid level upper part 3a, whereby the vaporization of the liquid fuel R' in the liquid level upper part 3a is accelerated by the air flowing into the liquid level upper part 3a in the fuel tank 2. Thus, the quantity of evaporative fuel S supplied to the internal combustion engine can be efficiently increased. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
