I was thinking of an alternate method of using ethanol in vehicles. Instead of just mixing it with the gasoline, one would have separate tanks, one for straight ethanol and one for straight gas. The fuel system would be separate up to and including the injectors. At a certain load (or signal from a knock sensor) the engine would swich fuels.

The higher octane rating of pure alcohol would enable us to do such things as increase compression ratio and boost, and possibly downsize the engine. As a result not only would we have better efficiency while burning ethanol, we'd have better efficiency while burning gasoline aswell.



Thoughts?
