MODEL OF IDEAL AIR STANDARD ATKINSON CYCLE
The first model introduced is the ideal air standard model of the Atkinson cycle. This hypothetical model assumes no losses, and constant specific heats of dry air. This model is the most simplistic, however it will be used as a guide to build other models based on it.

To begin the analysis of the Atkinson cycle, the first law of thermodynamics is applied to the cycle [2]:
