CONTROLLING EXHAUST GAS RECIRCULATION BY MEANS OF A LOAD SIGNAL ON AN IN-LINE INJECTION PUMP
The invention relates to an exhaust gas recirculation control system for internal combustion engines comprising an intake manifold (1) for delivering combustion air to the individual combustion chambers, an exhaust manifold (2) for discharging the exhaust gases from the combustion chambers, an exhaust gas recirculation pipe (3) that connects the intake manifold (1) and the exhaust manifold (2), and a mechanical injection pump (4) which is controlled by a control rod (5). The invention is characterized in that an electrically controlled exhaust gas recirculation valve (6) is disposed in the exhaust gas recirculation pipe (3) in order to control the effective cross section of the exhaust gas recirculation pipe (3) while an electrical tapping device (7) determines the position of the control rod (5) and then controls the exhaust gas recirculation valve (6).
