Abstract

There is provided a control system for an internal combustion engine. An amount of variation in the rotational speed of the engine is detected. A rotational speed variation reference value is calculated based on an averaged value of the detected amount of variation in the rotational speed of the engine. The detected amount of variation in the rotational speed of the engine is compared with the rotational speed variation reference value. The amount of fuel to be supplied to the engine is corrected based on results of the comparison.
