  • Air entrainment component for vehicle exhaust system
    Patent number: 8661798
    Abstract: A vehicle exhaust system includes an air entrainment component that is used to reduce exhaust gas temperatures exiting the vehicle exhaust system. The air entrainment component includes an exhaust pipe with a non-circular cross-section at one end and an overlap tube that substantially surrounds the non-circular cross-section to form an air gap between the exhaust pipe and the overlap tube. Cooling external air is drawn into the air gap to cool heated exhaust gases within the exhaust pipe.
