<P>PROBLEM TO BE SOLVED: To promptly supply vaporized fuel into a cylinder even at low temperature start, and to improve starting performance. <P>SOLUTION: An engine 10 includes a normal fuel tank 32, a vaporized fuel tank 36, an in-tank injection valve 38, a vaporized fuel supply valve 40, an in-tank ignition plug 44 or the like. An ECU 60 supplies the vaporized fuel to a surge tank 20 at the start-up while accumulating the vaporized fuel during the drive of the engine in the vaporized fuel tank 36 in advance. Furthermore, when the vaporized fuel is insufficient at the start-up, the ECU first burns the vaporized fuel remaining in the vaporized fuel tank 36 by using the in-tank ignition plug 44, and then injects the fuel into the vaporized fuel tank 36 which is heated by combustion from the in-tank injection valve 38. By this arrangement, even if inevitably generating the vaporized fuel at the start-up, the vaporized fuel can efficiently be generated in a short time, and the generated vaporized fuel can promptly be supplied into the cylinder. <P>COPYRIGHT: (C)2012,JPO&INPIT |
