Abstract
An exhaust Venturi apparatus, system, and method includes an elongate housing for passage of exhaust gases, a Venturi mechanism disposed on the housing, the Venturi mechanism configured to create a low-pressure zone in the exhaust gases within the housing, and an aperture disposed in a side of the housing downstream of the Venturi mechanism, such that secondary air outside the housing is drawn into the exhaust stream. The aperture may comprise one or a plurality of apertures, small in cross-section compared to the housing cross-section, for minimizing sound emanating from the exhaust system. The Venturi mechanism may comprise a Venturi plate mounted between the housing and the engine.
