An exhaust system includes an exhaust component with a wall having an outer surface and an inner surface that defines an internal exhaust gas flow path. At least one opening is formed in the exhaust component to extend through the 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 cover the at least one opening. A diverter is positioned adjacent the at least one opening to block at least a portion of the exhaust gas flow path.

Exhaust system component

A valve assembly for a vehicle exhaust system includes a rigid mount structure that is configured to be mounted within an exhaust component that defines an exhaust gas passage. The valve assembly further includes a plurality of flexible members that each extend from a first end to a second end. One of the first ends and second ends of the flexible members is fixed to the rigid mount structure and the other of the first ends and second ends is free to move such that the plurality of flexible members creates a variable restriction to flow through the exhaust component that varies in response to a pressure difference upstream and downstream of the plurality of flexible members.

Variable restriction valve for vehicle exhaust system

A vehicle exhaust system includes a hot end having one or more hot end exhaust components that treat emissions generated by an engine and a cold end that includes at least one cold end component that attenuates noise. At least one acoustic volume is in parallel or serial to the hot end to further attenuate noise.

Method and apparatus to enable package space reduction in a vehicle exhaust system

A vehicle exhaust system includes a first component that receives exhaust gas output from an engine and a second component that is fluidly coupled to the first component to define an upstream portion of a vehicle exhaust system. A vehicle frame member includes an internal acoustic volume. A pipe connects the internal acoustic volume in parallel to the upstream portion of the vehicle exhaust system.

Vehicle frame with acoustic volume for an exhaust system

An exhaust component assembly includes a component housing defined by an outer dimension and having at least one sensor opening. A sensor boss surrounds the at least one sensor opening and at least one exhaust component is positioned radially outwardly of the component housing and includes an opening that surrounds the at least one sensor opening. A first flange extends about an outer periphery of the sensor boss and a second flange is associated with the opening of the at least one exhaust component to accommodate variations in the outer dimension such that the first and the second flanges can be attached to each other.

Method and apparatus to accommodate sensors on an exhaust component

A vehicle exhaust system includes a first exhaust gas path and a second exhaust gas path. At least one valve is positioned within the first exhaust gas path and an active noise control system is associated with the second exhaust gas path. An example method includes, providing the first exhaust gas path with a first tailpipe having a first outlet and the second exhaust gas path with a second tailpipe having a second outlet separate from the first outlet. The valve and the active noise control system are controlled simultaneously to control noise generated by the vehicle exhaust system.

Exhaust valve and active noise control for compact exhaust system

An exhaust system includes first and second exhaust components with an inter-pipe that fluidly connects an outlet of the first exhaust component to an inlet of the second exhaust component. A passive valve is mounted within the inter-pipe. The second exhaust component defines an internal cavity that is at least partially packed with a high frequency absorption material and cooperates with the passive valve to effectively attenuate low and high frequency noise.

Passive valve and resonator assembly for vehicle exhaust system

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.

Exhaust valve combined with active noise control system

A dual exhaust system includes a first exhaust component defining a first exhaust path and a second exhaust component defining a second exhaust path that is different from the first exhaust path. A first valve is associated with the first exhaust path and a second valve is associated with the second exhaust path. The first valve and second valve operate independently of each other to vary exhaust flow and provide sufficient noise control for varying applications.
