9-143 Consider an engine operating on the ideal Diesel cycle with air as the working fluid. The volume of the cylinder is 1200 cm3 at the beginning of the compression process, 75 cm3 at the end, and 150 cm3 after the heat-addition process. Air is at 17°C and 100 kPa at the beginning of the compression process. Determine a) the pressure at the beginning of the heat-rejection process, b) the net work per cycle, in kJ, and c) the mean effective pressure. | |
