A four-cylinder, four-stroke, 2.2 liter gasoline engine operates on the ideal Otto cycle with a compression ratio of 10. The air is at 100kPa and 60ºC at the beginning of the compression process, and the maximum pressure in the cylinder is 8MPa. The air- fuel ratio is 16. Using constant specific heats at 850K, determine:

a) The temperature at the end of the expansion process

b) The thermal efficiency of the cycle
c) The mean effective pressure (MEP)
d) The engine speed in rpm for a net power output of 70kW
e) The specific fuel consumption, in g/kWh
