<P>PROBLEM TO BE SOLVED: To compatibly achieve improvement of dispersion action of exhaust gas and reduction of the pressure loss at a high level in a simple configuration, in an exhaust structure capable of controlling the flow of the exhaust gas of an internal combustion engine 1. <P>SOLUTION: An exhaust gas agitating device 20 includes a lot of twisted conical pipes 22 arranged in a circumferential direction in an exhaust passage 7 and twisted in the circumferential direction to the center line P<SB>2</SB>of the exhaust passage 7. When the exhaust gas passes through the twisted conical pipes 22, the exhaust gas is swirled and is made to flow out. The exhaust flow delivered from an inner diameter side space surrounded by the twisted conical pipes 22 and the swirl flow collide with each other, and the exhaust gas is dispersed to all the regions of the exhaust passage 7, and thereby, the exhaust gas is effectively agitated. <P>COPYRIGHT: (C)2010,JPO&INPIT |
