A variable throat injection injector control system, comprising: a chamber portion provided in a cylindrical shape; A first manifold in which a first flow path through which fluid flows to the chamber portion is formed in a tangential direction with respect to an outer surface of the chamber portion; A second manifold disposed below the first manifold and having a second flow path through which the fluid flows into the chamber section, the second flow path being formed in a tangential direction with respect to an outer surface of the chamber section; And a nozzle unit that receives a fluid from the chamber and ejects the fluid to the outside, wherein the cross-sectional area of the first flow path is larger than the cross-sectional area of the second flow path, the number of the first flow paths is three, The number of the second flow paths is four, and the longitudinal direction of the second flow path is perpendicular to the longitudinal direction of the first flow path. According to the present invention, there is provided a variable thrust injector injection flow rate control system capable of having an optimum spray angle variation rate.
