置。An intake passage and an exhaust passage of a diesel engine are connected by an appropriate exhaust recirculation pipe, and a throttle valve with a variable opening degree is installed in the intake passage and at a position upstream of the intake position from the opening position of the exhaust recirculation pipe. An exhaust gas recirculation device for a diesel engine is configured to control the recirculation amount of exhaust gas that is recirculated from the exhaust passage to the intake passage side via the exhaust gas recirculation pipe by a change in the negative pressure generated by the The other end opens downstream of the throttle valve.
and an opening/closing control device that closes the exhaust gas recirculation pipe and simultaneously opens the air supply pipe when the throttle valve fails to operate in the opening direction. Exhaust recirculation system for diesel engines.
