摘要： 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.

摘要： A vehicle exhaust system includes an exhaust component having an outer surface and an inner surface that defines an internal exhaust component cavity. At least one hole is formed in the exhaust component to extend through a wall of the exhaust component from the outer surface to the inner surface. A member is formed from a resistive material and is configured to overlap the at least one hole. At least one spacer is configured to space the member away from the inner or outer surface of the exhaust component to create an open cavity between the member and the exhaust component. In one example, an actuator is configured to cover and uncover the member dependent upon an operating characteristic to vary damping.

摘要： 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.

摘要： The exhaust pipe comprises an inlet pipe, an outlet pipe and a bend portion arranged between the inlet pipe and the outlet pipe. The bend portion comprises an inlet bend and an outlet bend, wherein a central bend portion defines an intermediate section of inlet bend and outlet bend and wherein the inlet bend and the outlet bend each cover 50 percent of the total bend angle covered by the bend portion. The central bend portion comprises a diameter, which is smaller than a diameter of the inlet bend and of the outlet bend in a bending plane. In addition a bend radius R of the bend portion varies along the bend portion such that a bend radius of the inlet bend is larger than a bend radius of the outlet bend.
