A four cylinder four-stroke internal combustion spark-ignition engine operates on the ideal cycle (the Otto cycle). The engine has a bore of 3.5 in and a stroke of 3.5 in. The compression ratio of this engine is 8.4. The engine is designed to operate with an air-fuel ratio of 16 with a fuel that has an energy content of 45,000 kJ/kg and a molar mass of 114 kg/kmol. Assume that the air and fuel mixture behave as an ideal gas mixture with the same properties as pure air. The pressure and temperature at the start of the ideal Otto cycle processes are 98 kPa, 32°C.

a.) What is the total engine displacement for all cylinders in liters?

b.) What is the maximum temperature occurring in the cycle?

c.) Determine the engine efficiency.
