A heat engine is a device that accepts heat from a high temperature reservoir, T H , performs externalwork, W, and rejects heat to a low temperature reservoir T L. The diagram shows a practical ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

Ever since the invention of water mills in antiquity, through the development of the steam engine in the 18th century, and up to today’s turbines, many power generators rely on the principle of ...
