2nd-Law Analysis of Otto Cycles Consider an engine operating on the ideal Otto cycle with a compression ratio of 8. At the beginning of the compression process, air is at 100 kPa and 17°C. During the constant-volume heat-addition process, 800 kJ/kg of heat is transferred to air from a source at 1700 K and waste heat is rejected to the surroundings at 290 K. Accounting for the variation of specific heats of air with temperature, determine (a) the exergy destruction associated with each of the four processes and the cycle and (b) the second-law efficiency of this cycle.
