Consider a modification of the cold air-standard Otto cycle in which the isentropic compression and expansion processes are each replaced with polytropic processes having n = 1.3. The compression ratio is 12 for the modified cycle. At the beginning of compression, p1 = 1 bar and T1 = 300 K and V1 = 2270 cm3. The maximum temperature during the cycle is 2000 K. Determine the work output in kJ, for the modified cycle.
