<P>PROBLEM TO BE SOLVED: To uniformize the flow of exhaust gas into an exhaust post-treatment device with simple and compact constitution. <P>SOLUTION: A current plate 7 which is formed by a plate member with a plurality of vent holes 8 is provided between the bending part 5 of an exhaust pipe 2 and an exhaust purifying catalyst 3 provided at the downstream side of the bending part 5. The diameter of the vent hole 8a positioned at the inner side of the bending direction of the bending part 5 is formed larger than that of the vent hole 8c positioned at the outer side of the bending direction of the bending part 5. <P>COPYRIGHT: (C)2010,JPO&INPIT |
