付デイーゼル機関の排気ガス再循環制御装置。 In a diesel engine in which a supercharger is disposed in an engine intake passage, a bypass passage is branched from an intake passage upstream of the turbocharger, and the bypass passage is connected to an intake passage downstream of the turbocharger, A bypass control valve that closes as the engine load increases is disposed, and a bench lily portion is formed in the bypass passage located between the intake passage upstream of the supercharger and the bypass control valve, thereby connecting the engine exhaust passage and the intake passage. Exhaust gas recirculation control for a turbocharged diesel engine, in which an exhaust gas recirculation control valve that opens as the negative pressure increases in response to the negative pressure in the bench lily is disposed in the connected exhaust gas recirculation passage. Device.
