    摘要: 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.
