At the beginning of the compression process of an air standard Otto cycle, p₁ = 1 bar, T₁ = 300 K. The maximum temperature in
the cycle is 2250 K and the compression ratio is 9.8. The engine has 4 cylinders and an engine displacement of V=2.6 L. Determine
per cylinder:
a) the volume at state 1.
b) the air mass per cycle.
c) the heat addition per cycle, in kJ.
d) the heat rejection per cycle, in kJ.
e) the network per cycle, in kJ.
f) the thermal efficiency.
g) the mean effective pressure, in bar.
h) Develop a full exergy accounting per cycle, in kJ. Let To = 300 K, P = 1 bar.
i) Devise and evaluate the exergetic efficiency for the cycle.
