=== Gas-only cycles ===
In these cycles and engines the working fluid is always a gas (i.e., there is no phase change):
*[[Carnot cycle]] ([[Carnot heat engine]])
*[[Ericsson cycle]] (Caloric Ship John Ericsson)
*[[Stirling cycle]] ([[Stirling engine]],<ref name="hae-stirling1842">{{cite web|url=http://hotairengines.org/closed-cycle-engine/stirling-1827/stirling-dundee-engine|title=Stirling's Dundee engine of 1841|work=hotairengines.org}}</ref> [[thermoacoustic refrigeration|thermoacoustic]] devices)
*[[Internal combustion engine]] (ICE):
**[[Otto cycle]] (e.g. [[petrol engine|gasoline/petrol engine]])
**[[Diesel cycle]] (e.g. [[Diesel engine]])
**[[Atkinson cycle]] (Atkinson engine)
**[[Brayton cycle]] or [[Joule cycle]] originally [[Ericsson cycle]] ([[gas turbine]])
**[[Lenoir cycle]] (e.g., [[pulse jet engine]])
**[[Miller cycle]] (Miller engine)
