Required information A four-cylinder, four-stroke, spark-ignition engine operates on the ideal Otto cycle with a compression ratio of 11 and a total displacement volume of 1.8 L. The air is at 90 kPa and 50°C at the beginning of the compression process. The heat input is 1.1 kJ per cycle per cylinder. The gas constant of air is R = 0.287 kJ/kg-K and use constant specific heats with cy= 0.821 kJ/kg-K, Cp = 1.108 kJ/kg-K, and k= 1.35.
