<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas recirculation device in an internal combustion engine which prevents condensate water reversely flowing from an exhaust gas recirculation pipe from being brought into contact with an exhaust emission purifying catalyst of an exhaust emission control device to prevent deterioration of the exhaust emission purifying catalyst. <P>SOLUTION: The exhaust gas recirculation device in an internal combustion engine includes plate-like members 41 and 42 facing across a gap in an opening direction from a DPF 16b to a low-pressure EGR pipe 20, in a case member 16a positioned between the downstream side of the DPF 16b and the upstream side of the low-pressure EGR pipe 20. Openings 41a and 42b are alternately arranged from an upper end to a lower end in the extending direction of the plate-like members 41 and 42, while preventing the entire surface of a plurality of the openings 41a and 42b provided on the plate-like members 41 and 42 from overlapping the opening direction from the DPF 16b to the low-pressure EGR pipe 20. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
