At the beginning of the compression of an otto cycle the air temperature is 300k and p1=atm. the compression ratio is 8. Max temperature is 2000k. Consider a cold air analysis and use k=1.4/ Cv=0.718 kj/kgK/ Cp=1.005 kj/kgK. Sketch the cycle using a P-V diagram, calculate max pressure, and heat transfer into the cycle per unit mass in kj/kg.
