A Carnot cycle is a special kind of cyclic process affecting a body composed of material suitable for use in a heat engine.

Grey-blue represents supercritical liquid water.) Entropy is the above-mentioned unexpected and, to some, obscure integral that arises directly from the Carnot cycle.
In the Carnot cycle, the working fluid returns to the same state it had at the start of the cycle, hence the line integral of any state function, such as entropy, over the cycle is zero.
Endoreversible heat engines The most Carnot efficiency as a criterion of heat engine performance is the fact that by its nature, any maximally efficient Carnot cycle must operate at an infinitesimal temperature gradient.
