PROBLEM TO BE SOLVED: To efficiently intake exhaust gas into flow of combustion air, and improve dispersion of the inside of expansion parts and recovery of pressure. SOLUTION: An internal combustion engine includes an air supplying part for combustion, an exhaust manifold, and an intake venturi. The intake venturi includes a combustion air intake port which is connected and communicated to/with a combustion air supplying part, an exhaust gas intake port which is connected and communicated to/with the exhaust manifold, and an exhaust port. A venturi zone is terminated at a venturi throat, and is communicated with the combustion air intake port. The expansion parts are disposed between the venturi zone and the exhaust port, and communicated therewith. At least one of the intake port is terminated so that it may come closer to the venturi throat at the inside of the expansion part. |
