Consider a modification of the 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 9 for the modified cycle. At the beginning of compression, p1=1bar and T1=300K and V1=2270 cm3. The maximum temperature during the cycle is 2000K. Determine: (a) the heat transfer and work in kJ, for each process in the modified cycle. (b) the thermal efficiency. (c) the mean effective pressure, in bar.
