PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of reducing an amount of fuel injection and reducing emission through stable combustion.SOLUTION: A fuel injection valve 10 arranged at a cylinder head 2 of an engine 1 comprises a first injection hole 11 and a plurality of second injection holes 12. The first injection hole 11 injects fuel toward a range where an electric discharge from an electrode 71 of a spark plug 7 reaches. The second injection holes 12 inject fuel toward an imaginary circle Q around a center of an axis O1 that includes the electrode 71 of the spark plug 7 and is in parallel with an axis of the cylinder 3. With this arrangement as above, fuel injected fog 110 injected from the first injection hole 11 is ignited with electric discharge of the spark plug 7, its flame is transmitted to all fuel injected fog 120 injected from the second injection holes 12. |
