装置。In an internal combustion engine equipped with an exhaust passage that guides burnt gas in a combustion chamber to the outside through an exhaust valve, the combustion chamber or the exhaust passage has an exhaust outlet near the exhaust valve, and the exhaust downstream of the exhaust outlet. A second exhaust passage having an exhaust outlet is provided in the passage, and the second exhaust passage includes an on-off valve that opens in the final region of the exhaust stroke, a storage space, and a pressure difference after the valve face in the direction of the exhaust outlet. An exhaust system for an internal combustion engine, characterized in that a one-way valve that opens is provided in order from the exhaust outlet to the exhaust outlet.
