Theoretical engines
The efficiency of a heat engine relates how much useful work is output for a given amount of heat energy input. From the laws of thermodynamics, after a completed cycle: and therefore where is the net work extracted from the engine in one cycle. (It is negative, in the IUPAC convention, since work is done by the engine.) is the heat energy taken from the high tem… WebbIn recent decades, the approach known as Finite-Time Thermodynamics has provided a fruitful theoretical framework for the optimization of heat engines operating between a …

The Stirling engine is one example of this. Therefore, the Carnot efficiency at a given hot section and cold section temperature is equal to the Stirling efficiency between the same hot and cold sections.
