To provide a fuel injection control device of a scramjet engine that can eliminate a choke phenomenon with a simple constitution.
The fuel injection control device of the scramjet engine has a combustion flow passage reaching the exhaust side via a combustion area from the intake side and a fuel injection part that can inject fuel toward the combustion area, performs supersonic combustion, and includes a pressure detecting part that can detect pressure in the combustion flow passage distributing over the exhaust side from the intake side and a control part that can control the fuel injection part based on the pressure detecting part. The control part performs choke avoiding control for controlling so that an increase pressure position becomes the exhaust side by holding a set pressure position (Step S4) when determining that the increase pressure position of increase pressure that can block up the combustion flow passage goes over to the intake side by holding the preset set pressure position from the detected pressure distribution (Step S3:Yes).
