Question

Consider an air-standard Otto cycle. At the beginning of the compression process, the pressure and temperature are 100 kPa and 300 K. The displacement volume is 2 liters, compression ratio is 10 and the pressure at the end of the combustion is 4 times the pressure at the end of the compression.
Use cold-air standard calculations and determine the pressure, temperature and volume at each state and fill in the below table:

2- Consider an air-standard Otto cycle. At the beginning of the compression process, the
pressure and temperature are 100 kPa and 300 K. The displacement volume is 2 liters,
compression ratio is 10 and the pressure at the end of the combustion is 4 times the pressure at
the end of the compression.
Use cold-air standard calculations and determine:
a) the pressure, temperature and volume at each state and fill in the below table:
p (kPa)
T (K)
V (m3)
State 1
State 2
State 3
State 4
b) the net work per cycle, in kJ
c) the thermal efficiency of the cycle.
