2. The pressure and temperature at the beginning of compression process of an air-standard Diesel

cycle are 100 kPa and 290 K, respectively. At the end of the heat addition, the temperature is 2000 K.

The compression ratio is 20. Sketch the process on a P-V diagram and T-s diagram. Using the cold-air

standard analysis, determine (i) pressure and temperature at the end of each process, (ii) cut-off ratio,

(iii) heat addition and rejection, in kJ/kg, (iv) work produced during the cycle, in kJ/kg, and (v) thermal

efficiency. (watch "Diesel cycle-example).
