摘要： An exhaust-gas-recirculation system for use in diesel engines, having a valve member adapted to control the flow rate of the exhaust gas recirculated from the exhaust pipe to the intake pipe of the diesel engine. The exhaust-gas-recirculation system has a fly-weight rotatable in synchronization with the engine to produce a centrifugal force, a governor sleeve displaceable in response to a thrust thereon given by the fly-weight, a control spring counteracting the thrust on the governor sleeve and having a spring load changeable in response to the change in the amount of depression of an accelerator pedal, and an actuator operative in response to the displacement of the governor sleeve to actuate the valve member.

摘要： An exhaust gas recirculation apparatus for diesel engines includes an exhaust gas recirculation passage for recirculating exhaust gases from an exhaust pipe to an intake pipe, a valve body for controlling the cross sectional area of the recirculation passage and a pressure regulator for detecting an amount of fuel injection and to output a signal. A diaphragm device is operatively connected to the pressure regulator to receive a pressure signal to control the position of the valve body, whereby in response to an increase of fuel injection the cross sectional area of the recirculation passage is decreased.
