An air standard diesel cycle operates at a maximum temperature and pressure of 3000 K and 8500 kPa. The air’s condition before entering compression stroke is 100 kPa at 300 K. a. Draw the cycle’s P-V and T-S diagrams (use state points 1-2-3-4 in order). b. Identify all unknown temperatures (K) and pressures (kPa) at 4 state points. c. Determine the compression ratio and cut-off ratio of the engine. d. Calculate the cycle’s thermal efficiency. e. What is the cycle’s mean effective pressure (kPa)?
