Abstract
An exhaust afterburner for positioning in an exhaust duct or the like of an internal combustion engine through which partially reacted gases are circulated is disclosed. The exhaust afterburner includes a venturi induction member which has a circumferential array of radially extending apertures for inducting a reacting gas into the exhaust duct upon passage of the partially reacted gases therethrough. A housing surrounds a venturi induction member and includes a first air intake opening in communication with the apertures of the venturi induction member as well as a second air intake opening disposed adjacent to the inlet end of the venturi induction member. A bushing is positioned within the housing at the second air intake opening with the bushing having a circumferential array of radially extending apertures in fluid communication with the second air intake opening. A mechanism for relieving back pressure is provided within the exhaust afterburner positioned within the exhaust afterburner housing.
