Glad you've come over to the dark side, aerobat!
All the arguments Oggers posted relating to small throttle settings (VE), or flame front speed, or burning fuel faster, or ignition timing blah blah blah - don't relate to the original post about thermodynamic cycle efficiency of low vs. high compression.
In fact, these problems disappear in a constant pressure heat engine like a turbine, where the concept is the same:
Less heat transferred to the fluid = more useable energy available
More useable energy available from same energy input = higher thermodynamic efficiency
I'd really like to hear Oggers explain how ignition timing, or valve timing, or mixtures, or flame fronts, or pumping losses, or any other of his false arguments explain why a high compression turbine engine is more efficient than a low compression turbine.
