Cycle	Compression, 1→2	Heat addition, 2→3	Expansion, 3→4	Heat rejection, 4→1	Notes
Power cycles normally with external combustion - or heat pump cycles:
Bell Coleman	adiabatic	isobaric	adiabatic	isobaric	A reversed Brayton cycle
Carnot	isentropic	isothermal	isentropic	isothermal	Carnot heat engine
Ericsson	isothermal	isobaric	isothermal	isobaric	The second Ericsson cycle from 1853
Rankine	adiabatic	isobaric	adiabatic	isobaric	Steam engine
Hygroscopic	adiabatic	isobaric	adiabatic	isobaric	Hygroscopic cycle
Scuderi	adiabatic	variable pressure and volume	adiabatic	isochoric
Stirling	isothermal	isochoric	isothermal	isochoric	Stirling engine
Manson	isothermal	isochoric	isothermal	isochoric then adiabatic	[[Manson-Guise Engine](leads to low info ad-based article)]
Stoddard	adiabatic	isobaric	adiabatic	isobaric
Power cycles normally with internal combustion:
Brayton	adiabatic	isobaric	adiabatic	isobaric	Jet engine. The external combustion version of this cycle is known as first Ericsson cycle from 1833.
Diesel	adiabatic	isobaric	adiabatic	isochoric	Diesel engine
Lenoir	isobaric	isochoric	adiabatic		Pulse jets. Note, 1→2 accomplishes both the heat rejection and the compression.
Otto	adiabatic	isochoric	adiabatic	isochoric	Gasoline / petrol engines
