    • An exhaust manifold is provided with a plurality of branch pipe parts and a collecting pipe part. The plurality of branch pipe parts are respectively connected to a plurality of exhaust ports of a multicylinder internal combustion engine. The collecting pipe part is formed by merging the plurality of branch pipe parts. The plurality of branch pipe parts and the collecting pipe part are formed by an upper shell member and a lower shell member superposed on each other. A partition plate is attached to at least one of the upper shell member and the lower shell member. The partition plate separates between exhaust gases flowing into the collecting pipe part from two of the branch pipe parts respectively connected to adjacent two of the plurality of exhaust ports.
    • 排气歧管设有多个支管部分和收集管部分。 多个支管部分分别连接到多缸内燃机的多个排气口。 收集管部通过使多个支管部分合并而形成。 多个分支管部和收集管部由彼此重叠的上壳部件和下壳部件形成。 分隔板附接到上壳体构件和下壳体构件中的至少一个。 分隔板从分别连接到多个排气口中的相邻两个排气口的两个分支管部分分离流入收集管部分的废气。
