    Thanks for inviting Dan as your guest. I really appreciate hearing from someone who has a good knowledge of the basic technologies competing for future application in auto propulsion systems. I was surprised, however, that he promoted the DOE desire for 100RON gasoline. Modern GDI engines are much like Diesel engines from a thermal efficiency and combustion point of view. Because there is little or no fuel during compression stroke, auto ignition is not a serious problem. So, no need for high RON. 14CR is about the best you can do for overall efficiency (combined thermal and mechanical) That’s why you see modern pistons engines near this level.
