A spark ignition engine operating on the ideal Otto cycle takes in air at 98 kPa and 25C at the beginning of the compression stroke. The compression ratio is 9.2 and the total volume (all cylinders combined) at the beginning of the compression stroke, is 2.1 L. Operating conditions dictate that the maximum temperature during the cycle not exceed 1850 C. Using cold-air standard assumptions, calculate the a) Pressure, temperature and specific volume at the end of each process b) Net work output for each cycle (kJ) c) Thermal efficiency of the cycle d) Mean effective pressure (kPa)
