Solved: A four-cylinder, four-stroke internal combustion

Chapter 9, Problem 9.14

(choose chapter or problem)

A four-cylinder, four-stroke internal combustion engine has a bore of 3.7 in. and a stroke of 3.4 in. The clearance volume is 16% of the cylinder volume at bottom dead center and the crankshaft rotates at 2400 RPM. The processes within each cylinder are modeled as an air-standard Otto cycle with a pressure of \(14.5 \mathrm{lbf} / \mathrm{in} .^{2}\) and a temperature of \(60^{\circ} \mathrm{F}\) at the beginning of compression. The maximum temperature in the cycle is \(5200^{\circ} \mathrm{R}\). Based on this model, calculate the net work per cycle, in Btu, and the power developed by the engine, in horsepower.
