    Abstract: An exhaust mechanism includes: an exhaust pipe configured to circulate exhaust gas from an engine; a first outer pipe disposed along the exhaust pipe on an outer periphery of the exhaust pipe; a second outer pipe disposed along the first outer pipe on an outer periphery of the first outer pipe; a pair of intermediate members disposed on the outer periphery of the exhaust pipe, fixed to respective inner peripheral surfaces of a first end portion and a second end portion of the first outer pipe, and being lower in thermal conductivity than the exhaust pipe. A vacuum layer is provided between the first outer pipe and the second outer pipe. At least one of the intermediate members is configured to slide in an axial direction of the exhaust pipe.

    Abstract: A snap-action valve assembly for an exhaust system is provided that includes a first conduit and a second conduit that are joined to together to define an exhaust passageway. A valve flap is disposed within the exhaust passageway for controlling exhaust flow. A shaft supports the valve flap in the exhaust passageway for rotation between open and closed positions. First and second bushings support the shaft. A pad made of wire mesh is attached to the valve flap. The pad includes an end portion that contacts the first or second conduit in the closed position and side wings that contact the first or second conduit in the open position. A resilient tongue may support the pad on an angle relative to the valve flap and a mass damper may be attached to one end of the shaft. These features dampen vibration and reduce valve flap flutter.

    Abstract: A marine muffler adapted with an internally tunable sound suppression structure is adaptable to different configurations thereby allowing for structural adjustments to optimize sound suppression and minimize backpressure for particular engine and exhaust conditions. A muffler housing defines an interior volume and includes an exhaust inlet and outlet. The outlet has a reduced diameter as compared with the inlet such that the exhaust gas accelerates through the muffler. An inclined baffle partitions the interior volume into a lower chamber in communication with the exhaust inlet and an upper chamber in communication with the exhaust outlet. Exhaust ducts attached to each side wall penetrate the baffle thereby placing the upper and lower chambers in fluid communication. A corrugated partition divides each exhaust duct into a plurality of non-circular conduits. The muffler may be tuned by selectively capping one or more conduit outlets.

    Abstract: An exhaust system of a saddle-ride type vehicle includes an end cap and a muffler close to each other to achieve uniformity therebetween and which is capable of preventing the occurrence of a knocking sound. The exhaust system of a saddle-ride type vehicle includes a muffler connected to an exhaust pipe for discharging exhaust of an engine E and an end cap is attached to a muffler rear end portion. In the end cap, an insertion portion thereof is inserted into and held by an end cap inserted portion provided in the muffler rear end portion, and multiple protruding portions are formed on an outer surface of the insertion portion at a predetermined interval in a circumferential direction of the outer surface. The multiple protruding portions come in contact with an inserted portion inner peripheral wall surface of the end cap inserted portion.
