3. A six-cylinder, 4-stroke, spark-ignition engine operating on the ideal Otto cycle takes in air at 15 psia and 65 F, and is limited to a maximum cycle temperature of 1650 F Each cylinder has a bore of 3.5 in, and each piston has a stroke of 4.5 in. The minimum enclosed volume is 12 percent of the maximum enclosed volume. Use constant specific heats at room temperature. Determine a. V, V b. Temperature at all 4 states c. mar per cylinder d. Qin, qout e. Power produced @ 2500 rpm. 4. A four cylinder, two-stroke 2.5L diesel engine that operates on an ideal Diesel cycle has a compression ratio of 22 and a cutoff ratio of 1.4. Air is at 70C and 105kPa at the beginning of the compression process. Using cold-air-standard assumptions, determine how much power the engine will deliver at 3000 rpm
