A bypass passage 10 extending from the intake passage portion 20a of the supercharging pump 5 to the downstream 20b of the supercharging pump
The exhaust gas inlet 24a of the exhaust gas recirculation passage 24, which recirculates part of the exhaust gas from the exhaust passage 23 to the intake system, is connected to the bypass passage 10. Supercharging pump 5 downstream 20b J side port 10b
Exhaust gas recirculation fatigue of a supercharged engine is characterized by its installation in the intake passage 2.0b, which is more downstream. 2. The bypass passage 10 is equipped with a dial ram type supercharging pressure control valve 30 that opens the bypass passage 10 when the absolute value of the negative pressure of the flow 20a on the supercharger 5 becomes higher than a predetermined value using the throttle valve 4''QfE. 3. The device according to claim 1 of the utility model registration provided therein. 3. The exhaust gas recirculation passage 24 includes an exhaust gas recirculation passage 24 located upstream of the throttle valve 4 when the throttle valve 4 is fully closed, and located upstream of the throttle valve 4 after the throttle valve 4 is slightly opened. A utility model registration claim 1 or 2 is provided in which the diaphragm type exhaust gas flow control valve 25b opens the passage when the absolute value of the negative pressure of the pressure port 33 located downstream becomes higher than a predetermined value. equipment.
