Otto, Diesel, and Dual Cycles

A four-cylinder, four-stroke internal combustion engine operates at 2800 RPM. The processes within each cylinder are modeled as an air-standard Otto cycle with a pressure of 14.7 lbf/in.², a temperature of 80°F, and a volume of 0.0196 ft³ at the beginning of compression. The compression ratio is 10, and maximum pressure in the cycle is 1080 lbf/in.² Determine, using a cold air-standard analysis with k = 1.4, the power developed by the engine, in horsepower, and the mean effective pressure, in lbf/in.²
