In an individual cylinder control apparatus having a closed-loop control system for controlling an average speed of an internal combustion engine, the operation timing of the engine is detected and a timing signal for each cylinder, showing a predetermined measurement period determined to include at least that part of the period during which torque is produced due to fuel combustion in the cylinder concerned during which no influence arises because of torque produced in cylinders other than the cylinder concerned, is output in response to the result of the detection. In response to the timing signal, difference data representing the difference between the output from each cylinder and that from a predetermined reference cylinder among the cylinders is calculated. Individual cylinder control data related to the supply of fuel necessary for reducing the difference to zero is produced in response to the difference data, and the individual cylinder data is output and provided to the closed-loop control system at a predetermined timing before the next fuel regulating process for the individual cylinders, whereby the fuel quantity for each cylinder is regulated so as to make the respective output of the cylinders the same.
