At the beginning of the compression process of an air-standard Diesel cycle, p1 = 1 bar, V1 = 6 litter, and T1 = 310 K. The maximum temperature is 2000 K. The displacement volume of an internal combustion engine is 5.6 liters. Determine (a) the net work per cycle, in kJ, (b) the thermal efficiency, and (c) the entropy produced in one cycle ignore the stray heat (hint: it is the summation of the produced entropy in the processes 1-2, 2-3, and 3-4).
