Abstract
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.
