  • Cross-exit exhaust system
    Patent number: 6662900
    Abstract: An exhaust system features first and second exhaust conduits fluidly coupled to first and second cylinder banks of an associated internal combustion engine. The first and second conduits cross over each other downstream of the engine and are coupled together by a common chamber. The common chamber allows pressure pulses in the first and second conduits flowing past the chamber in opposite directions to at least partially cancel each other, thereby reducing low frequency exhaust noise.
    Type: Grant
    Filed: December 21, 2001
    Date of Patent: December 16, 2003
    Assignee: DaimlerChrysler Corporation
    Inventors: John D Cathcart, James P Salmonowicz
