Abstract of the Disclosure An exhaust gas recirculation control system for an internal combustion engine for removing nitrogen oxides (NOx) in exhaust gases comprises a positive pressure delay valve in a negative pressure passage for introducing intake negative pressure in the proximity of a throttle valve of a carburetor into an exhaust gas recirculation control valve to maintain the negative pressure therein during an accelera- tion, thereby effecting the exhaust gas recirculation even when accelerating to purify the nitrogen oxides in the exhaust gas. The exhaust gas recirculation control system further comprises a positive pressure delay valve in an advance negative pressure passage for introducing the intake negative pressure in the vicinity of the throttle valve of a carburetor into a distributor and synchronized with the above positive pressure delay valve to maintain the distributor advanced, thereby keeping a good combustion of fuel mixture.
