The initial conditions for an ideal air-standard Otto cycle operating with a compression ratio of 8:1 are 0.95 bar and 17°C. At the beginning of the compression stroke, the cylinder volume is 2.20 liters (L) and 3.60 kJ of energy is added as heat transfer during the constant-volume heating process.
