Abstract
A muffler and exhaust extractor especially adapted for internal combustion engine powered vehicles such as over the road diesel tractors. The muffler and exhaust extractor generally stated comprises a pair of spaced curved airfoils for directing the airstream produced by the moving vehicle through an open ended converging-diverging passage to form a low pressure area for gas extraction, and means for mounting the airfoils such that the low pressure area is adjacent to and in communication with the exhaust outlet of the vehicle.
