The pseudo Stirling cycle, also known as the adiabatic Stirling cycle, is a
thermodynamic cycle
A thermodynamic cycle consists of a linked sequence of thermodynamic processes that involve transfer of heat and work into and out of the system, while varying pressure, temperature, and other state variables within the system, and that eventuall ...

adiabatic working volume and
isothermal
In thermodynamics, an isothermal process is a type of thermodynamic process in which the temperature ''T'' of a system remains constant: Δ''T'' = 0. This typically occurs when a system is in contact with an outside thermal reservoir, and a ...
heater and cooler, in contrast to the
ideal Stirling cycle with an isothermal working space.
The working fluid has no bearing on the maximum thermal efficiencies of the pseudo Stirling cycle.
Practical
Stirling engine
A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of air or other gas (the ''working fluid'') between different temperatures, resulting in a net conversion of heat energy to mechanical work.

s usually use a adiabatic Stirling cycle as the ideal Stirling cycle can not be practically implemented.
Nomenclature (practical engines and ideal cycle are both named Stirling)
[https://sgp.fas.org/othergov/doe/lanl/pubs/00326875.pdf ] and lack in specificity (omitting ''ideal'' or ''adiabatic'' Stirling cycle) can cause confusion.
History
The pseudo Stirling cycle was designed to address predictive shortcomings
in the
ideal isothermal Stirling cycle. Specifically, the ideal cycle does not give usable figures or criteria for judging the performance of real-world
