The displacement volume of an internal combustron engine is 5.6 liters. The processes within each
cylinder of the engine are modeled as an air-standard Diesel cycle with a cutoff ratio ß of 2.4. The
state of the air at the beginning of compression is fixed by P 95 kPa, T=
liters. For air, take specific heat ratio y 1.4, and R 0.287 kJ kg.K.
Determine the net work per cycle, in kl. //int find the temperatures at all states and apply
Ocycle= Weycle)
b. If the net work per cycle is equal to 4.78 kJ. determine the indicated mean effeetive pressure
in kPa,
Determine the thermal efficiency.
d. Determine the power developed by the engine, in kW, if the cycle is executed 1500 times
27°C, and V = 6.0
