Problem 1 A diesel engine has a compression ratio r = 20 and uses air as the working fluid. The state of air at the beginning of the compression process is P1 = 95 kPa and T = 20°C. However, the isentropic expansion normally occuring between state 3 and state 4 is replaced by a polytropic process along which: Pul.35 = constant. The maximum temperature in the cycle is not to exceed 2200 K. In this analysis, the variation of...
