A diesel engine has air as the working fluid at 215 kPa and 315 K before the compression process. A
peak pressure of 15 MPa and a peak temperature of 2000 K occur during the cycle. Using variable 
specific heats, determine (a) the compression ratio, (b) the thermal efficiency, and (c) mean effective 
pressure (kPa). Draw (d) a P-v diagram and (e) a T-s diagram.
