An exhaust gas recirculation control system for an internal combustion engine comprises a pressure detector responsive to exhaust gas pulsations for detecting pressure in an exhaust gas recirculation passage which is closely associated with an exhaust gas recirculation flow rate to detect any deviation of the detected pressure from a desired value previously determined depending upon the engine operating conditions and thereby to control the exhaust gas recirculation flow rate in a feed-back control so as to eliminate any deviation in pressure. |
