Question: (6 points) A 4.4L spark-ignition engine operates on the ideal Otto cycle with a compression ratio of 9 . At the beginning of the compression

(6 points) A 4.4L spark-ignition engine operates on the ideal Otto cycle with a compression ratio of 9 . At the beginning of the compression process the air is at 93kPa and 25C. The maximum cycle temperature is 1130C. Using the cold-air standard assumptions, determine: the heat addition per cycle kJ the net work per cycle kJ the mean effective pressure (MEP) kPa the thermal efficiency % If the engine operates at 3500rpm, what is the power output of the engine? hp (6 points) A 4.4L spark-ignition engine operates on the ideal Otto cycle with a compression ratio of 9 .
