In an control apparatus for controlling a timing of injection of fuel to be injected into an internal combustion engine, the apparatus comprises a closed loop system in which the data showing the actual timing of injection of of fuel is fed back. When the condition of the operation of the engine becomes a predetermined state, the control system is changed from the closed loop system to another system in which an adjusting member for adjusting the timing of injection of fuel is controlled by a signal which is not related to the actual timing of injection. As a result, the stability of the operation in low engine speed zone is remarkably improved.
