A four-cylinder, four-stroke, 2.2-L gasoline engine operates on the Otto cycle with a compression ratio of 10. The air is at 100 kPa and 60°C at the beginning of the compression process, and the maximum pressure in the cycle is 8MPa. The compression and expansion processes may be modeled as polytropic with a polytropic constant of 1.3. Using constant specific heats at 850 K, determine;
a) The temperature at the end of the expansion process,
b) the net work output and the thermal efficiency,
c) total volume of the engine and the total mass contained in the cylinder.
