Abstract
An output control system for an internal combustion engine includes an engine output lowering magnitude command component outputting a command indicative of a magnitude to lower the engine output, an engine operating condition judgement component responsive to an engine output control command to make a judgement at every combustion timing on whether a cylinder scheduled for next combustion is or is not to be placed into a resting state, a cylinder resting performing component for disabling combustion at the combustion timing for which resting is determined by the judgement component, and a storage for storing judgment results made by the judgement portion during a predetermined number of immediately preceding combustion timings. The judgement portion compares a command output by the engine output lowering magnitude command component and past judgement results stored in the storage portion, and makes a present judgement as to whether the cylinder scheduled for the next combustion is or is not to be placed in resting condition on the basis of a result of the comparison.
