項記載の排気ガス再循環装置。1. In an engine that has a throttle valve 4 upstream of a supercharger 5 and a cooling device 16 downstream of it that cools supercharged air, exhaust gas. Exhaust gas recirculation that recirculates a portion from the exhaust passage 11 to the intake passage 10a upstream of the turbocharger and downstream of the throttle valve! The passage 12 is passed through or near the cooling device 16 to cool the recirculating gas, and a condensed water reservoir 20 is provided downstream of the cooling part of the recirculation passage 12. The condensed water discharge means connects the condensed water reservoir 20 downward to the intake air passage 10b downstream of the supercharger. The discharge passage includes a constriction 22 that limits the amount of condensed water flowing into the discharge passage.
and a check valve 23 that prevents positive pressure during supercharging from being transmitted to the condensed water reservoir.Claim 1 of Utility Model Registration
Exhaust gas recirculation device as described in section.
