Zusammenfassung:	PROBLEM TO BE SOLVED: To uniform the concentration of additive agent in exhaust.SOLUTION: In an exhaust passage 2 of an internal combustion engine, agitation means 1 is provided which separates a flow of exhaust into a spirally flowing spiral flow and a straight flow flowing in the center of the spiral flow in a direction of the center axis of the exhaust passage 2. Even if the spiral flow deflects the additive agent toward a wall face of the exhaust passage, the additive agent delivered by the straight flow increases the concentration of the additive agent in the center axis of the exhaust passage. 【課題】排気中の添加剤の濃度を均一にする。【解決手段】内燃機関の排気通路２において、排気の流れを、螺旋状に流れる螺旋流と、該螺旋流の中心において排気通路２の中心軸方向に進む直進流と、に分ける攪拌手段１を備える。螺旋流により添加剤が排気通路の壁面側に偏ったとしても、直進流によって運ばれる添加剤により、排気通路の中心軸側の添加剤の濃度を高める。【選択図】図１
