An Otto cycle is to be used to model an engine cycle. All assumptions of the ideal Otto cycle are to be applied except a polytropic process with n = 1.3 will be used for the expansion process. The conditions at the beginning of compression are T1 = 333 K, P1 = 90 kPa and the compression ratio is 8. The energy input into the cycle during the constant volume process is 2000 kJ/kg. Assume constant specific heats. a) Find the peak temperature of the cycle. (K) b) Find the temperature at the end of the expansion process. (K) c) Find the expansion work (kJ/kg)

Question
An Otto cycle is to be used to model an engine cycle. All assumptions of the ideal
Otto cycle are to be applied except a polytropic process with n = 1.3 will be used for
the expansion process. The conditions at the beginning of compression are T1 = 333
K, P1 = 90 kPa and the compression ratio is 8. The energy input into the cycle during
the constant volume process is 2000 kJ/kg. Assume constant specific heats.
a) Find the peak temperature of the cycle. (K)
b) Find the temperature at the end of the expansion process. (K)
c) Find the expansion work (kJ/kg)
