PROBLEM TO BE SOLVED: To remove liquid film fuel remaining on a nozzle surface of a fuel injection valve effectively with a simple structure. SOLUTION: One end of a guide member 5 which consists of thin wire material or the like is fixed on a nozzle part 3 of the fuel injection valve 1, and another end of the guide member 5 is attached to an inner wall of an intake pipe 50 so as to touch at a position in a lower side in a gravity direction at least more than a fuel injection hole. Consequently, fuel film on a tip surface of the nozzle part 3 travels on a guide member 5 and drops on an inner wall of the intake pipe 50 and is atomized by air flow before enlargement. Deterioration of exhaust emission and fuel economy due to sucking fuel of coarse particle diameter into the engine and oil dilusion can be prevented. COPYRIGHT: (C)2007,JPO&INPIT
