摘要： 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.

In the closed-loop control system, there is provided an individual cylinder control system in which a first data relating to outputs of respective cylinders of the engine is produced in response to an operation timing of the engine and the differential data showing the difference between the output of the respective cylinder and the output of a reference cylinder is calculated on the basis of the first data. A second control data relating to the fuel amount necessary for nullifying the difference indicated by the differential data is also produced in the latter system and the second data is supplied to the closed-loop control system, whereby the difference among the outputs of the cylinder is reduced.
