ABSTRACT:
This invention relates in the main to the extraction of gases from moving vehicles, by means of a chamber having long narrow discharge aperture, and being mounted in the air-flow past the vehicle. Features of the invention include the provision of aerofoils to direct or control air-flow past the discharge aperture, and the provision of holes in the chamber which may admit some air-flow to the interior of the chamber additional to gases already passing through it. A further feature is the positioning of chamber and/or aerofoils so as to cause a downward thrust to be imposed on the vehicle. The chamber may process or extract gases coming from a passenger/driver compartment, from a high pressure area beneath the vehicle to improve road-holding, and from the exhaust ports of an engine. An apparatus is provided within the chamber for the acoustic treatment of gases and such apparatus may be adapted to configurations suited to the invention.
