I'm no 'gear-head' but, also to consider that there is approximate 18,000:1
ratio volumetric from liquid to vapor. Therefore, there could be some
expected advantage to vaporizing the atomized (liquid) fuel inside the
cylinder. The expansion of the gas alone may account for some
energy/torque, while also using some of the available heat.

Talk about grasping at straws.
The most efficient conversion would be at the highest temperature. It is ,
after all, a HEAT engine. Unfortunately we have no commercial materials that
can withstand a stoichiometric mix. An engine run with a stoichiometric mix
first burns the exhaust valves and if it runs long enough devours the
pistons as well. Hitlers boys researched an engine that ran red hot but
never got it out of the lab.
The best practical engine I know of is a Bourke. The Experimental Aircraft
Association had and perhaps still publishes a paper about it. Had 50:1
compression for those that understand why.
