PURPOSE:To prevent interference in exhaust of respective cylinders. and to prevent deterioration in efficiency of a turbo charger by displacing an EGR pipe to one side of a partitioning wall inside an exhaust manifold with respect to a plural number of cylinders, and by connecting the EGR pipe to the exhaust manifold. CONSTITUTION:Exhaust gas of an engine is exhausted to a manifold 12, and an exhaust turbine 21 is driven. An compressor 17 which is directly connected to the exhaust turbine 21 is interlocked so as to compress intake air, and it is supplied to the engine through an inter cooler 18 of an intake pipe 13. A part of exhaust gas is returned to the intake pipe 13 from the exhaust manifold 12 through an EGR pipe 22. In this case, the pipe 22 is displacedly attached to one side of an partitioning wall 26 with respect to front and rear cylinders of the exhaust manifold 12 so that the EGR pipe 22 may take out only exhaust gas from one side of each front or rear cylinder of the engine. Consequently, interference in exhaust of respective cylinders is prevented, and also deterioration in effect of the exhaust turbine 21 is prevented. |
