![A
gasoline-powered engine runs in an Otto cycle with a compression ratio of CR = 10: 1. The intake air
is at 100 kPa = 1 bar, 20 °C, and the chamber volume is 500 cm³ before the compression stroke. The
temperature at the end of an adiabatic expansion is T4 = 950 K.
Specific heat capacity at a constant air pressure at atmospheric pressure and room
temperature: cp = 1.01 kJ/kgK.
Specific heat capacity at constant air volume at atmospheric pressure and room temperature:
cv = 0.718 kJ/kgK.
K = cp/cv = 1.4
