I'm not talking about Sadi Carnot's engine.
In the case of a usual heat engine, it absorbs heat from a hot reservoir, does work and releases a small amount of heat to the cold reservoir. In a cyclic process, the system undergoes many thermodynamic processes. I don't understand which process (isothermal/isobaric/isochoric) is used here.How is it a cyclic process?
One more question is it irreversible cyclic process?
In Sadi Carnot's heat engine, the cyclic process is composed of the above mentioned thermodynamic processes which makes it reversible.
