PROBLEM TO BE SOLVED: To provide an exhaust recirculation device suppressing deterioration of a supercharger. SOLUTION: In a turning part 100 provided in an upstream side of a compressor 42, one part of intake and EGR gas conducted by an LPL-EGR part 70 are turned and mixed, and separation objects are centrifuged. By this, since condensed water deposited by dropping of a temperature of the EGR gas and foreign substances in exhaust are centrifuged, and not supplied to the supercharger 40, breakage and deterioration of the supercharger 40 can be suppressed. Since one part of the intake and the EGR gas are mixed by turning in the turning part 100, temperature unevenness of air for supercharging can be reduced. Since air for supercharging having no temperature unevenness is supplied to the supercharger 40, breakage and deterioration due to heat distortion of the supercharger 40 can be suppressed. Since only one part of the intake is turned along with the EGR gas, pressure loss can be reduced in comparison to when turning a whole of the intake. COPYRIGHT: (C)2011,JPO&INPIT
