Abstract
An exhaust gas control system has a proximal end for connection to a distal end of an exhaust pipe and has a first divergent and convergent and second divergent portions. Curved spiralling blades extend around inner walls of the first divergent and convergent portions leaving an open central space about which exhaust gas whirls. The second divergent portion exhausts the swirling gas through a distal opening. A duct surrounds the convergent and second divergent portions and controls flow of ambient air over those portions.
Claims9
An exhaust gas control system comprising an exhaust gas guiding pipe having a proximal end configured for attachment to a distal end of an exhaust pipe, the guiding pipe having a first divergent portion beginning with the proximal intake end and having a second convergent portion spaced from the intake end and having a plurality of longitudinally extending spiralling blades centrally converging adjacent said proximal end for spiralling exhaust gasses from the exhaust pipe.
