  • Vehicular exhaust resonator with cooling feature
    Patent number: 7845465
    Abstract: A vehicular exhaust resonator features an exhaust inlet conduit which narrows down in a manner such as to define a venturi effect region. Air entrainment apertures in the housing of the resonator provide fluid communication between outside cooling air and an air inlet chamber in the resonator. A further air inlet aperture in an outlet conduit section of the resonator is in fluid communication with the air inlet chamber. Due to the venturi effect inside the inlet conduit, a pressure drop is created to pull air from the outside into the air inlet chamber and then into an outlet conduit of the resonator for mixing with the exhaust gas to provide cooling thereof.
