PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of restraining noise of an exhaust manifold even when the length of branch parts is shortened. SOLUTION: This internal combustion engine has a cylinder head 1 forming exhaust ports 20A to 20C respectively connected to three cylinders 10A to 10C. The internal combustion engine has the branch parts 32A to 32C respectively connected to the exhaust ports 20A to 20C and an aggregation part 34 for aggregating the branch parts 32A to 32C. The exhaust ports 20A to 20C and the branch parts 32A to 32C are pointed in the exhaust downstream direction A of the aggregation part 34. COPYRIGHT: (C)2007,JPO&INPIT
