The inclusion of a regenerator differentiates the Stirling engine from other closed cycle hot air engines.
2.
A very simple thermoacoustic hot air engine is the Rijke tube that converts heat into acoustic energy.
3.
Essentially, it would have been a hot air engine using a turbine instead of a piston.
4.
A praxinoscope made by Ernst Plank, of Nuremberg, Germany, and powered by a miniature hot air engine.
5.
He invented a hot air engine known as the " Surge Turbine " for which he was granted a US patent.
6.
Examples include steam in a steam engine, air in a hot air engine and hydraulic fluid in a hydraulic motor or hydraulic cylinder.
7.
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.
8.
It has been used in various internal combustion engines, such as the Bourke engine, SyTech engine, and many hot air engines and steam engines.
9.
The term " hot air engine " specifically excludes any engine performing a thermodynamic cycle, such as the Rankine cycle, in which the working fluid undergoes a phase transition.
10.
Towards the end of his life Faure was granted further patents, among them ones for the manufacture of aluminium alloys and improvements to hot air engines and motor vehicle steering mechanisms.
