EXHAUST VALVE COMBINED WITH ACTIVE NOISE CONTROL SYSTEM

摘要

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.
