McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc.
An engine or exhaust-driven fan or impeller used to provide additional fuel-air mixture to the engine so that it can produce additional power. This is done by forcing more fuel-air mixture into the cylinders than could be done by a normally aspirated engine at ambient atmospheric pressure. Supercharging prevents the loss of power with an increase in altitude and helps maintain the manifold pressure. See also turbocharger.
