I assume your talking about complete/ideal combustion? I noticed your reaction equation has been simplified a little.Burning Ethanol (E100) is simply,
C2H5OH + 3 O2 → 2 CO2 + 3 H2O(l)
So the byproducts are just CO2 and Water.
Whereas, burning Gasoline produces hundreds of complex Carbon chain byproducts that are very nasty. And because the combustion of Gasoline is not very efficient, it produces soot, and Carbon Monoxide. In addition to large amounts of CO2.
So burning Ethanol is cleaner over-all, than burning Gasoline, but not perfect by far. Especially since no one uses Ethanol (E100) in their cars. Most use E85, which is only 85% Ethanol, and 15% Gasoline.
As a Combustion Engineer, this kind of stuff is what I deal with everyday at work...
I've been told ethanol produces roughly 10% fewer emissions than gasoline.
Dang is this thread old!
