Question

An Otto cycle takes in air at 1 bar and 15 °C. The compression ratio is 8 to 1 and 2000 kJ/kg of energy released to air in each cycle. To what value must the compression ratio be raised to increase the net work per cycle by 20 percent ? ...(Take specific heat ratio for air = 1.4).

Step 1

The Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. It consists of two adiabatic processes and two isochoric processes. The given parameters are: - Initial pressure \( P_1 = 1 \) bar - Show more…
