Because the steam engine described is a heat engine of the external-combustion type, the cycle experienced by the working medium can be executed without combustion. In some steam engines, for example, the required input heat is supplied by a nuclear reactor. Stirling engines have been operated on radiant energy supplied by the sun.

Key to Stirling Engine. The air flows both through and around the porous displacer. The displacer looks like a piston but it is not. 

The engines designed by Stirling and those who followed him were very innovative engines, hut there was a problem with the material that was used to build them. In a Stirling engine, the hot side of the... 

Four phases of the Stirling engine power cycle. 

As electricity became more widely available in the early 1900s, and as gasoline became readily available as a fuel for automobiles, electric motors and gasoline engines began to replace Stirling engines. 

Stirling engines also have the maximum theoretical possible efficiency because their power cycle (their theoretical pressure volume diagram) matches the Carnot cycle. The Carnot cycle, first described by the French physicist Sadi Carnot, determines the maximum theoretical efficiency of any heat engine operating between a hot and a cold reservoir. The Carnot efficiency formula is... 

Stirling engines do not develop power immediately after the heat source is turned on. It can take a minute or longer for the hot side of the engine to get up to operating temperature and make full power available. Automobile drivers are used to having full power available almost instantly after they start their engines. 

There are no explosions inside Stirling engines, so they can be designed to be extremely quiet. The Swedish defense contractor Kockums has produced Stirling engine powered submarines for the Swedish navy that are said to be the quietest submarines in the world. 

Stirling engines that run on low temperature differences tend to be rather large for the amount of power...
