  • Patent number: 7131514
    Abstract: A noise attenuation device for a vehicle exhaust system is provided. The device includes an exhaust pipe having a passageway for receiving exhaust gas pulses from an engine. The device further includes a plurality of vanes extending from an inner surface of the passageway and spaced apart from one another. The vanes are configured to reduce turbulence in the exhaust gas pulses flowing past the vanes to reduce noise at a downstream outlet of the exhaust pipe.
    Type: Grant
    Filed: August 25, 2003
    Date of Patent: November 7, 2006
    Assignee: Ford Global Technologies, LLC
    Inventors: Michael Choi, Amir Keyvanmanesh
  • Patent number: 7086498
    Abstract: A noise attenuation device for a vehicle exhaust system is provided. The device includes an exhaust pipe having a passageway for receiving exhaust gas pulses from an engine. The device further includes a plurality of vanes extending from an inner surface of the passageway and spaced apart from one another and disposed upstream of a discontinuity in the exhaust pipe. The vanes reduce turbulence in the exhaust gas pulses flowing past the vanes to reduce noise at the exhaust pipe discontinuity.
