Slightly off-topic, why has no-on mentioned diesel engines (that run on
Jet-A1)? This has got to be the way to go, better economy, better operation
at altitude, simpler mechanicals (less to break) and FADEC/ECU controlled?

Actually, because of the higher compression ratios, the mechanicals are not simpler.

I know that the forces generated during compression are higher at a
higher compresion ratio, but I cannot imagine that they are higher
than the power forces. Now whether the power forces (peak) are higher
in a compression ignition engine ... maybe (and probably), but I've
never seen data from conn rod strain gages.
