ABSTRACT:
In the optimum control for an internal combustion engine wherein the engine is operated by dithering a value of a selected one of engine operating control variables from a value of the selected control variable which is obtained by calculation in accordance with detected values of operating parameters of the engine, and a direction of improving either one of a fuel consumption rate and an output of the engine is decided on the basis of a detected change of an engine operating condition, thereby correcting the calculated value of the selected control variable, during the time period of each dithered engine operation, an engine speed is detected two or more times and used for deciding the direction of a change of the engine speed, thereby providing an improved optimum control method and apparatus for internal combustion engines capable of preventing undesired correction control of the control variable from being effected in response to a change of the engine speed caused by any factor of disturbance.
