Question:

The compression ratio of an air standard Otto cycle is 8.7. Prior to the isentropic compression process, air is at 120 kPa, 19oC, and 660 cm3. The temperature at the end of the isentropic expansion process is 810 K. Using the PG model, determine
(a) The highest temperature and pressure in the cycle,
(b) The amount of heat transfer in kJ,
(c) The thermal efficiency and
(d) MEP.
