I've run gasoline in a spark ignited engine with 20:1 compression ratio by messing with the "obvious". pgfpro has gone even higher with dynamic ratios exceeding 30:1. How? By running much leaner combustion mixtures than even Honda's Lean-burn engines. Go look up his work on various threads. It's deep reading if you know a thing or two about combustion thermodynamics and thermo-chemistry. Its simply outright fun if you don't.

Sounds interesting for sure, I'll look into it
