ABSTRACT:
A method of controlling an operating amount of an operation control means for controlling the operation of an internal combustion engine having an intake passage and an intake air quantity control means for adjusting the opening area of the intake passage to thereby regulate the quantity of intake air of the engine. The operating amount of the operation control means, such as a fuel injection control means, is controlled to required values dependent on operating conditions of the engine, in synchronism with generation of pulses of a predetermined control signal. When the engine is operating in a predetermined low load condition, a desired operating amount of the control means is determined on the basis of the detected value of the intake passage opening area. A correction value is determined on the basis of a difference between the detected value of the intake passage opening area and the actual value of same, to correct the desired operating amount, and the operating amount is controlled to the corrected desired operating amount. Preferably, the correction value is determined in synchronism with generation of pulses of the predetermined control signal, from the desired operating amount based on the detected value of the intake passage opening area, and a second desired operating amount determined on the basis of the detected values of intake passage pressure downstream of the intake air quantity control means and the rotational speed of the engine. The correction value may alternatively be determined on the basis of a given voltage supplied from a variable voltage-creating means which is humanly adjustable.
