気装置。 A partition is provided at the exhaust port of the engine, and the partition divides the exhaust port into a first port on the cylinder head side and a second port on the crankcase side, and both ports and the muffler are connected by a common exhaust pipe. A first passage connected to the first port part and a second passage connected to the second port part are provided inside the exhaust pipe.
A control valve is formed downstream of the first passage and is closed when the engine speed decreases, so that the first passage closed by the control valve forms a resonance chamber when the engine speed decreases. An exhaust system for an internal combustion engine, characterized by:
