PURPOSE:To prevent a crack of a manifold, gas leak and breakage of a tightening bolt, by providing connecting parts which absorb thermal expansion and contraction at two positions, that is, between cylinders No.2 and No.3 and between cylinders No.5 and No.6, and then controlling a movement of the exhaust branch. CONSTITUTION:A front exhaust branch 3 is formed of each exhaust branch 25A for cylinders No.1 and No.2, and a rear exhaust branch 5 is formed of the exhaust branch 25A of a cylinder No.6. A center exhaust branch 4 is formed of each exhaust branch 25A for cylinders No.3-No.5 and an outlet 35 of exhaust gas for each of the cylinders No.1-No.6. The outlet 35 is provided on a position corresponding exactly to the cylinder No.5 and is offset from the center of exhaust manifold 25. |
