An ideal Diesel cycle has a compression ratio of 20 and cut-off ratio of 1.5. At the beginning of the compression stroke, air is at 100 kPa, 300 K. Use the cold-air-standard assumptions with property value cp = 1.005 kJ/kg-K. Assume cp / cv = 1.4. For this cycle, the net work output per unit mass is
- A. 335 kJ/kg
- B. 395 kJ/kg
- C. 500 kJ/kg
- D. 165 kJ/kg
Answer: A. 335 kJ/kg
