Question:
In an Atkinson engine the following data are obtained: compression in 2 of 100kpa at 25 ° C until reaching 3 where the pressure is 5bar.
The addition of heat at v = constant is carried out up to a final pressure of 18 bar.
Adiabatic expansion from 4-1 until in! pressure = 100 kPa. Furthermore, heat rejection occurs at constant pressure 1-2.
a) Calculate for theoretical air the work done per unit mass
b) Cycle efficiency
c) Mean pressure with displaced volume v2-v3
