ABSTRACT:
To prevent inflow of condensed water to an exhaust gas recirculation (EGR) valve, an exhaust gas recirculation system includes a first gas passage, an exhaust gas recirculation valve connected to the first gas passage and selectively opening/closing the first gas passage, an exhaust gas passage disposed in the exhaust gas recirculation valve, and a second gas passage connecting the exhaust gas passage to an air-fuel mixture passage. The exhaust gas passage is tilted at an obtuse angle with respect to the second gas passage. The angle may be less than about 170°, and in some embodiments the angle is about 165°.
