A 4 liter, 4-stroke compression ignition engine operating as an ideal dual cycle with a compression ratio of 14 produces 125 kW of net power at 3600 rpm when pressure and temperature at the start of compression are 95 kPa and 20°C respectively. 25% of the heat added during combustion occurs at constant volume, after which heat addition continues at constant pressure until complete. The working fluid cools as it expands during the power stroke, ending when the piston reaches bottom dead center at a temperature of 1140K. Using variable specific heats, determine: i. Cylinder pressure at the end of the compression stroke Maximum temperature and pressure during the cycle The cut-off ratio 11. iii.
