I need the answer as soon as possible An engine working on dual cycle has bore of 25 cm and stroke of 40 cm. Thepressure and temperature at the beginning of the compression are 1 bar and57°C, respectively. The heat supplied in the cycle is 1200 kJ/kg, two-third ofthis being added at constant volume and rest a constant pressure. If theclearance volume is 0.00178 m3, determine the maximum pressure andtemperature in the cycle, expansion ratio, thermal efficiency and MEP.

Consider a cylinder of a gasoline engine at the beginning of the compression cycle, duringwhich a fuel/air mixture (for our purposes mostly composed of nitrogen and oxygen, i.e.an ideal gas of diatomic molecules) at 300 K and 1 bar is compressed down to one-tenthvolume (compression ratio of 10:1). Assume that the compression is rapid so no heatexchange occurs with the environment. Calculate the pressure and the temperature ofthe compressed gas. In a diesel engine, the compression ratios are typically much higher;redo the same calculation with a compression ratio of 20:1.
