Wikipedia Overview
An external combustion engine is a reciprocating heat engine where a working fluid, contained internally, is heated by combustion in an external source, through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism of the engine, produces motion and usable work. The fluid is then dumped, or cooled, compressed and reused.
In these types of engines, the combustion is primarily used as a heat source, and the engine can work equally well with other types of heat sources.
