A four cylinder, four-stroke, spark ignition engine has a compression ratio of 10 and runs at 2400 rpm. Each cylinder has a bore of 7.6 cm and each piston has a stroke of 9.8 cm. The processes within each cylinder are modeled as an air-standard Otto cycle. At the beginning of the compression process (state 1), the air is at 290 K and 80 kPa. The combustion adds 1100 kJ/kg to the air. Determine:
