In case your selection was a gasoline engine, evaluate the performance of a four-cylinder four-stroke engine that operates on the ideal Otto cycle and has a compression ratio of 11. At the beginning of the compression process, the air is at 90 kPa and 27°C, and 500 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Accounting for the variation of specific heats of air with temperature, determine the required power the engine will deliver at 3000 ??? then compare your answer if your selection is two strokes.
