デイーゼル機関の吸気絞り装置。 In the intake throttle device of a diesel engine that performs exhaust gas recirculation, there is an intake throttle valve that is connected in conjunction with the accelerator pedal and throttles the intake air when the accelerator pedal is released, and a maximum closing position of the intake throttle valve that is connected to the accelerator pedal to throttle the intake air when the accelerator pedal is released. An intake throttle device for a diesel engine, comprising variable setting means for changing the maximum valve closing position to a valve open side when exhaust gas recirculation is being performed compared to when exhaust gas recirculation is not being performed.
