After reading through this a bit, in reference to Smokey's patents, we researched them a bunch and there is more to it than was ever released, even in the patents. Trish (his daughter) can attest to that and has (sort of). Past issue (Sept. I believe) of Hot Rod Magazine talks about that.
Most all auto manufactures are utilizing the techniques now well known to produce much higher mileage cars utilizing some thermal dynamic and physics basics. Soon they will have optimized the many control aspects to these Ultra Lean Burn systems in the ICE. Nothing new, just not made available to the buying public.
btw, Lee Iaccoca squashed the "Adiabatic" system back when proposed by Smokey and Carroll Shelby to Chrysler. Kinda ruined the relationship between Carrol and Smokey. Got that info and much more from Carrol himself back in 98. I owned a motoring publication and interviewed many people. (just an fyi)
This is what we're working on now
