To provide a technique for forming uniform air-fuel mixture, in a fuel injection device for an internal combustion engine having a plurality of fuel injection valves for directly injecting fuel into a cylinder of the internal combustion engine.
The fuel injection device for an internal combustion engine has two fuel injection valves 6, 7 which can inject fuel in the cylinder 4 of the internal combustion engine. The fuel injection valves are different in relative angle made between a direction oriented by an injection hole of each of two fuel injection valves 6, 7 and a surface orthogonal to a cylinder axis, so that the fuel injected from two of the fuel injection valves 6, 7 is rotated in a cylinder axis direction.
