Abstract
The present invention provides gas discharge technique useful on vehicle engines. The technique comprises an s-shaped duct having an ejector formed therein to mix hot exhaust gas with a relatively cooler airflow entrained by the ejector. The s-shaped duct may be comprised of a number of segments that when integrated form the s-shape and ejector. A variety of cross sections including circular and rectangular are provided for the s-shaped duct. The segments may be composed of smaller subsections and may further have cooling slots. A nacelle is provided to at least partially enclose the s-shaped conduit and may have an inlet that is in fluid communication with the ejector of the s-shaped conduit.
