An engine working on dual cycle has bore of 25 cm and stroke of 40 cm. The pressure and temperature at the beginning of the compression are 1 bar and 57°C, respectively. The heat supplied in the cycle is 1200 kJ/kg, two-third of this being added at constant volume and rest a constant pressure. If the clearance volume is 0.00178 m³, determine the maximum pressure and temperature in the cycle, expansion ratio, thermal efficiency and MEP.
