PROBLEM TO BE SOLVED: To prevent turbulence of intake and a tendency of injection fuel, sticking to respective partitions, by providing an engaging part, comprising a hollow part continued over the total circumference of a peripheral surface and a groove part with both ends leading to the hollow part, in a tip end surface of an injection part appearing in the partition separating an intake port to have each nozzle of a fuel injection valve. SOLUTION: In a fuel injection device 26, a side of a fuel chamber 6 in an intake port 28 provided in a cylinder head 4 is separated into each intake port part 32, 34 by a partition 30. In a fuel injection valve 38, each nozzle 42, 44 is provided in an injection part 140 in the tip end side. Further in the partition 30, an inserting hole of the injection part 40 is provided. An engaging part 56 is provided in the injection part 40, and an interposition unit 58 as a seal unit is provided. Then, the engaging part 56 is formed by a circular annular hollow part 64 continued over the total circumference of a peripheral surface 62 in a tip end surface 60 of the injection part 40 and a linear groove part 66 with the both ends leading to the hollow part 64 through between each nozzle 42, 44. In this way, a bad influence by each intake port part 32, 34 interfering with each other is prevented. |
