Consider a cold air standard Otto cycle for a 4-stroke engine with four cylinders. The compression ratio is 9. At the beginning of the compression the air in each cylinder is at 95 kPa, 5 C and occupies a volume of 555 cm^3. During the heat addition process the pressure triples. Determine the efficiency of the cycle and the net power output (per kg of air). If the engine is running at 2800 RPM determine the power output in horsepower....
