PURPOSE:To improve the reliability in durability by preventing the thermal deterioration of a flexible pipe due to exhaust gas. CONSTITUTION:An exhaust manifold 8 is equipped with the first exhaust manifold constitution body 51, second exhaust manifold constitution body 52, and a flexible pipe 56 which connects the first and second exhaust manifold constitution bodies 51 and 52 and is elastically deformable. The first exhaust manifold constitution body 51 is installed between the first cylinder group A of an engine 1 and a main turbocharger 10, and the second exhaust manifold constitution body 52 is installed between the second cylinder group B of the engine 1 and a subturbocharger 11. Further, the flexible pipe 56 is arranged at the position deflecting to the subturbocharger 11 side from the center C between both the exhaust manifold constitution bodies 51 and 52. |
