At the beginning of the compression process of an air-standard Otto cycle, P1=1bar, T1=290K, V1=400cm3. The maximum temperature in the cycle is 2200K and the compression ratio is 8. Determine the (a) heat addition, in kJ, (b) ????, in kJ, (c) thermal efficiency, and (d) mean effective pressure, in kPa. Consider the cycle as a model of the processes in each cylinder of a spark-ignition engine. Determine the (e) net power output, in kW, if the engine has four cylinders and the cycle is repeated 1200 times per minute in each cylinder. Also, (f) show the T-s and P-? diagrams. Note that the specific heats are NOT constant.
