A six-cylinder, four-stroke, spark-ignition engine operating on the ideal Otto cycle takes in air at 100 kPa and 25oC, and is limited to a maximum cycle temperature of 900oC. Each cylinder has a bore of 3.5 in, and each piston has a stroke of 3.9 in. The minimum enclosed volume is 14% of the maximum enclosed volume. How much power will this engine produce when operated at 2500 rpm? Use constant specific heats at room temperature.
