Abstract
An engine control apparatus works to determine a target value of each of performance parameters associated with different types of performances of a combustion engine based on operating conditions of the combustion engine, determine target values of combustion parameters associated with combustion states of fuel in the combustion engine based on the target values of the performance parameters using first correlation data representing correlations between the performance parameters and the combustion parameters, and calculate command values of controlled parameters for actuators as a function of the target values of the combustion parameters. When actual values of the performance parameters are in coincidence with the target values, the system changes or corrects the target value of a selected one of the performance parameters so as to enhance the level of a corresponding one of the performances of the engine based on the other performance parameters.
