Abstract
An output torque control system capable of control the internal combustion engine output torque in fast response to an engine load change. The ignition timing is controlled in a manner to reduce the difference between the actual torque and the demand torque, the difference being cause by an engine load change. The demand torque and the actual torque are calculated in accordance with preselected engine operating parameters such as engine rotation frequency. A corrected torque value is calculated based upon the demand torque and the actual torque. An ignition advance correction value which corresponds to the correction value is calculated. The engine ignition timing is corrected for the advance correction value so as to provide an engine output torque equal to the demand torque.
