  "textContent": "It is an object of the present invention to reduce the penetration of a fuel spray directed toward a certain area in a cylinder, thereby reducing oil dilution that increases sliding resistance in the engine, reducing fuel adhesion or the like onto the cylinder liner, and also reducing the adverse effect of a fuel spray having an increased penetration. A fuel injection valve that has a plurality of injection holes and injects fuel into a cylinder 3 of an internal combustion engine includes: injection holes a2 and a6 having a larger diameter for injecting fuel toward a ring-shaped space T1 including areas A2 and A6 of strong tumble flow T formed in the cylinder; and injection holes a1, a4, a3 and a5 having a smaller diameter for injecting fuel toward a space including areas A1, A4, A3 and A5 of weak tumble flow formed in the cylinder 3. A fuel spray from an injection hole having the larger diameter has a penetration force to the tumble flow larger than the penetration force of a fuel spray from an injection hole having the smaller diameter.",
