Assuming cold air standard assumptions for a spark ignition engine cycle (Otto) and given the following data: Compression ratio = 9 Intake air is at 14.5 psia and 80 deg F Heat added during the heat addition process: 15000 btu/lb (note: this is equal to the heating value of gasoline) Find: theoretical efficiency for this cycle maximum temperature for the cycle, deg F maximum pressure for the cycle, psia.
