Abstract: PROBLEM TO BE SOLVED: To improve sure and stably running of an internal combustion engine by forming extension zones for an impact wave pipe, connecting the extension zones together by a connecting pipe and a cross-section reduced part for causing to connecting pipe to function as an orifice. SOLUTION: Two impact wave pipes 6 and 7 load-applied by a plurality of cylinders 1 to 4 to an internal combustion engine and connected to the gas entrances 10 and 11 of the exhaust gas turbine 5 of an exhaust gas turbo supercharger are provided and the cylinders 1 to 4 and the impact wave pipes 6 and 7 are connected to each other by connecting pipes 8 and 9. In this case, extension zones 12 and 13 for the impact wave pipes 6 and 7 are formed in the upstream sides of the connecting pipes 8 and 9 farthest from the exhaust gas turbine 5, the pipes 6 and 7 are connected to the extension zones 12 and 13 and these zones are connected to each other by a connection pipe 14. A cross-section reduced part 15 functioning as an orifice is provided in this connecting pipe 14.
