Question
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 V₁ = 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 net work 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, Po = 1 bar.
i) Devise and evaluate the exergetic efficiency for the cycle.
Understand air-standard Otto cycle
Which statement is true for this air-standard Otto cycle?
O Heat is added to the air at constant volume.
O Heat is added to the air at constant pressure.
O Heat is rejected from air at constant pressure.
O None of the answers provided.
