To provide a technology for promoting combustion by controlling a fuel spray, in a fuel spray control device of an internal combustion engine.
This fuel spray control device has a fuel injection valve 9 directly injecting the fuel spray into a combustion chamber 3, and an air spraying mechanism 10 for changing pointing of the fuel spray injected by the fuel injection valve 9, and forms a first swirl flow C1 by the fuel spray by turning the fuel spray to the corner in the combustion chamber 3. Afterwards, the fuel spray is turned to the corner in the combustion chamber 3 on the opposite side of a case of forming the first swirl flow C1, and a second swirl flow C2 is formed of the fuel spray of reverse rotation of the first swirl flow C1, and the first and second swirl flows C1 and C2 are collided with each other.
