What is the stirling engine?

 

A Stirling engine is a heat engine that operates by cyclic compression

and expansion of air or other gas, the working fluid, at different

temperature levels such that there is a net conversion of heat energy to

mechanical work.The engine is like a steam engine in that all of the

engine's heat flows in and out through the engine wall.

 

How it works?

 

This is traditionally known as an external combustion engine in contrast

to an internal combustion engine where the heat input is by combustion

of a fuel within the body of the working fluid. Unlike the steam engine's

use of water in both its liquid and gaseous phases as the working fluid,

the Stirling engine encloses a fixed quantity of permanently gaseous

fluid such as air or helium. As in all heat engines, the general cycle

consists of compressing cool gas, heating the gas, expanding the hot

gas, and finally cooling the gas before repeating the cycle.
