The displacement volume of an internal combustion 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 of 2.4. The state of the air at the beginning of compression is fixed by p1 = 95 kPa, T1 = 27C, and V1 = 6.0 liters. Determine the net work per cycle, in kJ, and the thermal efficiency.
