Transcribed Image Text:

Operation of a heavy-duty, single-cylinder, diesel engine is modeled by the air standard constant pressure cycle with a cut-off ratio of 3. The engine has a displaced volume of 3 L and the state of the intake air at the beginning of compression is given by: pi = 150 kPa, T1 = 325 K, and Vi= 3.2 L. a. Draw the engine cycle on a p-V diagram clearly indicating all the states of the working fluid. b. Calculate the gross indicated work per cycle in kJ. c. Calculate the gross indicated power produced by the engine at 1000 rev/min in kW. d. Calculate the gross Indicated Mean Effective Pressure (IMEP9) in kPa. e. Calculate the thermal efficiency of the cycle. Operation of a heavy-duty, single-cylinder, diesel engine is modeled by the air standard constant pressure cycle with a cut-off ratio of 3.
