A gasoline internal combustion engine can be modeled by an ideal Otto cyclethat has a compression ratio of 8.91. At the beginning of the compression process (state 1), airis at 100 kPa and 300 K. The heat transfer into the air during the constant-volume heat additionprocess (state 2 to 3) is 693.08 kJ/kg.
