A six-cylinder, four-stroke internal combustion engine with compression ratio of 17 and displacement volume of 4.5 L is modeled using the ideal diesel cycle. Consider air in the cylinder is at 95 kPa and 57 degrees C at the start of compression. The engine operates at a speed of 2000 rpm. Heat input of 6.63 kJ occurs in every cycle. Consider variable specific heats for air.
(a) Calculate the maximum pressure (kP) and maximum temperature (degrees C) in the cycle.
(b) Determine the cut-off ratio of the cycle.
(c) Calculate thermal efficiency (%) of the cycle.
(d) Find the mean effective pressure (kPa) of the cycle.
(e) What is the total power output (kW) of the engine?
(f) Show the cycle on T-s diagram. Label states and show property values.
