ABSTRACT:
An exhaust gas recirculation system for diesel engines including an exhaust gas recirculation passage and a recirculation control valve for controlling the gas flow in the recirculation passage. A control circuit is provided for controlling the operation of the control valve. The control circuit receives an engine speed signal and a position signal which represents the angular position of the control lever in the fuel injection pump and closes the control valve to cut-off the exhaust gas recirculation when the engine speed signal becomes smaller than the position signal.
