The regenerator is the key component invented by Robert Stirling, and its presence distinguishes a true Stirling engine from any other closed-cycle hot air engine. Many small 'toy' Stirling engines, particularly low-temperature difference (LTD) types, do not have a distinct regenerator component and might be considered hot air engines; however ...
These engines may be based on a number of thermodynamic cycles encompassing both open cycle devices such as those of Sir George Cayley [3] and John Ericsson [4] and the closed cycle engine of Robert Stirling. [5] Hot air engines are distinct from the better known internal combustion based engine and steam engine.
A desktop gamma Stirling engine. The working fluid in this engine is air. The hot heat exchange is the glass cylinder on the right, and the cold heat exchanger is the finned cylinder on the top. This engine uses a small alcohol burner (bottom right) as a heat source
The Stirling cycle is a thermodynamic cycle that describes the general class of Stirling devices. This includes the original Stirling engine that was invented, developed and patented in 1816 by Robert Stirling with help from his brother, an engineer .

This apparatus consists of a large dish that concentrates solar energy to a focal point at the center of the dish. The concentrated solar energy drives a Stirling cycle engine, [2] which operates by letting heat flow from a hot source to a cold sink to do work. [3] The work output of the Stirling cycle then drives a generator to create electric ...
Stirling was optimistic that the new steel would improve the performance of the air engines. Robert Stirling's development of the hot air engine was in part motivated by safety. His engine was designed to fail far less catastrophically than the steam engines of the time while obtaining greater efficiency. [2]
Cycles that model external combustion engines include the Brayton cycle, which models gas turbines, the Rankine cycle, which models steam turbines, the Stirling cycle, which models hot air engines, and the Ericsson cycle, which also models hot air engines.
