求の範囲第１項記載の装置。[Claims for Utility Model Registration] 1. In an internal combustion engine equipped with a slot valve 4 upstream of a supercharger 5, a portion of exhaust gas is transferred from an exhaust passage 11 to an intake passage 1.
A path 12a connecting an exhaust gas recirculation path 12 for recirculation to 0a, 10b downstream of the throttle valve and upstream of the supercharger, and a path 12 connecting downstream of the supercharger.
A supercharger that branches into b and allows recirculation gas to flow upstream of the supercharger 5 during positive pressure supercharging, and to flow downstream of the supercharger 5 when not during positive pressure supercharging. Engine exhaust gas recirculation system. 2 Pressure port 15 located upstream when the throttle valve 4 is fully closed, and downstream after the throttle valve is slightly opened.
When a becomes a negative pressure above a certain level, the passage 12b connected to the downstream side of the supercharger 5 is opened, and when the pressure coupler downstream of the supercharger 15b becomes a positive pressure above a certain level, the overflow is opened. The device according to claim 1, which has been registered as a utility model and is provided with pneumatic control valves 13 = 13a, 13b which open the path 12a connected to the upstream side of the feeder 5.
