An exhaust gas recirculation control system for internal combustion engines includes an intake pipe () for delivering combustion air to the individual combustion chambers, an exhaust pipe () for discharging the exhaust gases from the combustion chambers, an exhaust gas recirculation line () that connects the intake pipe () and the exhaust pipe (), and a mechanical injection pump () which is controlled by a control rod () is disclosed. An electrically controlled EGR valve (exhaust gas recirculation valve) () is located in the exhaust gas recirculation line () in order to control the effective cross section of the exhaust gas recirculation line () while an electrical pick-off device () determines the position of the control rod () and then controls the EGR valve ().
