Otto cycle problem:A four cylinder, four stroke, spark-ignition engine operating on the ideal Otto cycle
takes in air at 20 psia and 100F, and is limited to a maximum cycle temperature of 3000F. Each cylinder
has a bore of 3 in, and each piston has a stroke of 4 in. The minimum enclosed volume of each piston is
20% of the maximum enclosed volume. How much power will this engine produce when operated at
3500 rpm?
