Abstract: An adaptive valve assembly includes a pipe defining a passageway for conducting engine exhaust gases, a pivot shaft supported by the pipe, and a valve body coupled to the pivot shaft. The valve body is moveable between an open position where exhaust gas flow through the passageway is increased and a closed position where exhaust gas flow through the passageway is reduced. A spring biases the valve body toward the closed position. The spring includes a plurality of coils that have torsional displacement relative to each other as the valve body moves between the open and closed positions. A torsional damper feature is associated with at least one coil of the plurality of coils to provide torsional spring damping.

Abstract: An adaptive valve assembly includes a pipe defining a passageway for conducting engine exhaust gases, a pivot shaft supported by the pipe, and a valve body coupled to the pivot shaft. The valve body is moveable between an open position where exhaust gas flow through the passageway is increased and a closed position where exhaust gas flow through the passageway is reduced. A resilient member biases the valve body toward the closed position. A retainer cooperates with the resilient member to define a valve stop for the valve body when in the closed position.

Abstract: 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.

Abstract: A vehicle exhaust system includes at least one exhaust component that defines an exhaust passage from an engine to an exhaust outlet. An active noise attenuation component is associated with the exhaust component. A valve is positioned within the exhaust component downstream of the engine and upstream of the active noise attenuation component. The valve and active noise attenuation component cooperate with each other to control noise generated by the exhaust system.
