A variable noise attenuation element is disclosed that comprises a tube, at least one valve seat, at least one valve body and a wire connected to the valve body. The tube has an overall length that defines a first effective length for noise attenuation. The valve seat is disposed in the tube. Retraction of the wire brings the valve body into engagement with the valve seat to selectively define a second effective length of the tube that is less than the overall length.

An intake silencer device is described herein. The intake silencer device includes an outer housing and a plurality of sequential arranged expansion chambers separated by walls. The intake silencer device further includes an inner tube positioned in each of the sequential chambers, each of the inner tubes including an opening providing fluidic communication between an interior of the tube and the corresponding expansion chamber, a size of the openings increasing in size sequentially in a downstream direction.

Intake system having a silencer device

An apparatus and method for customizing the sound emitted from an automotive vehicle during operation. Specifically, the vehicle operator uses a controller to vary the sound emitted from the engine exhaust and intake or engine compartment sounds during vehicle operation. In addition, the operator can control the sound level, sound type and sound aspect in the vehicle interior or passenger compartment and the vehicle exterior. Further, the apparatus uses an active sound control system, such as those using microphones and speakers, to customize and/or tune the sound emanating from the vehicle.

Method and apparatus for selectively varying motor vehicle sounds

A resonator is disclosed which includes: a sleeve insert and an outer duct sealingly coupled to the sleeve insert. The sleeve insert has a wall with a first aperture in the wall at a first axial distance, a second aperture in the wall at a second axial distance, and a rib extending radially outwardly with the rib located between the first and second apertures. The outer duct sealingly couples to the sleeve insert proximate first and second ends of the inner sleeve and at the rib. The sleeve insert and the outer duct are formed of plastic materials which are coupled by welding or via o-rings placed on the sleeve insert. Cavities, in the vicinity of the apertures, are formed in the outer duct. The cavities, which are fluidly coupled to the sleeve insert via the apertures, attenuate noise.

Acoustic silencer

An air induction arrangement for a variable displacement engine is provided. The air induction arrangement includes first and second plenums fluidly connected to respective first and second throttles . The first and second throttles are connected to respective first and second inlets . In partial operation, the air induction arrangement induces air into the first plenum . In higher power demand operation, the air induction arrangement additionally induces air through the second plenum . There is a reduction of the cancellation of acoustic output between the first and second inlets so that an acoustic output of the engine operating with only a first group of cylinders is similar to the acoustic output of the engine when the engine is operating with both groups of cylinders
