DEVICE FOR LOWERING TAIL PIPE EXHAUST TEMPERATURE

摘要

A component for a vehicular exhaust pipe includes an upstream venturi forming portion for creating at least a partial vacuum interior to the component. A downstream diverter housing portion of the component has an inlet coupled to an outlet of the venturi portion. The diverter housing portion includes the diverter element positioned adjacent an output of the diverter housing portion for forcing axially central exhaust flow radially outward toward a wall of the diverter housing. The partial vacuum in the component device causes colder environmental ambient air to enter an inlet of the component. The diverter also creates a mixture of hot exhaust flow with the colder environmental air, resulting in a lower temperature of the exhaust gas exiting the component and substantial elimination of centrally disposed exhaust hot spots. ® KIPO & WIPO 2009
