Problem 9.6
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/in², 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/in². 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/in².
