Otto Cycle Efficiency<br />
Otto Cycle: The theoretically most efficient cycle for an IC engine.<br />
• 1-2: isentropic compression<br />
• 2-3: constant volume heat addition<br />
• 3-4: isentropic expansion<br />
• 4-1: constant volume heat removal<br />

CR = compression ratio = V BDC /V TDC<br />
γ = C p /C v = ratio of specific heats<br />
Otto Cycle efficiency is a function of CR and γ.<br />
