ABSTRACT:
A method of controlling an operation of an internal combustion engine. A memory has stored therein a plurality of basic values of a control amount by which the operation of the engine is to be controlled, and which conform to at least one operating parameter of the engine, as well as at least one correction value for correcting the basic values. When each of first and second conditions is detected under which the operation of the engine is required to be controlled by respective different amounts, ones of the basic values are read from the memory, which corresponds to the value of the at least one operating parameter. When a predetermined one of the first and second conditions is detected, the at least one correction value is read from the memory, by which the read basic values are corrected by the read correction value. The operation of the engine is controlled by control amounts based upon the corrected basic values. The operation of the engine includes control of fuel supply to the engine and exhaust gas recirculation control.
