At the beginning of the compression process of an air-standard diesel cycle operating with the compression ratio r = 18, the temperature is T1=300K and the pressure is p1=0.1MPA. The temperature at the end of the combustion process (the highest temperature of the cycle) is T3=1800K. a) Plot the cycle on the p-v and T-v diagrams. b) Determine the cutoff ratio rc. c) Find the temperature at the end of each process of the cycle. d) Evaluate the efficiency of the cycle.
