Consider an air-standard Otto cycle, whose two isentropic processes are replaced with polytropic processes with a polytropic exponent n = 1.35. The compression ratio is 8, P1 = 100 kPa, T1 = 25°C, and the maximum cycle temperature is 1200°C. Determine the heat transferred to and rejected from this cycle, net work output, as well as the cycle's thermal efficiency. Please consider air as ideal gas with variable specific heats.
