I'm still questioning it all Motie ;-) Your Vehicle - Ethanol performs! Compatibility and warranty protection "If the ethanol concentration increases well above 10%, for example to 20% ethanol, or even "neat" (near 100%) ethanol as is used in Brazil, a higher engine compression ratio is necessary to take advantage of the ethanol's higher octane rating (compared to normal gasoline). Higher compression ratios can, in turn, mean greater pressure on engine bearings, so engines must be designed for this."

Just the basics: Ethanol Transportation for the 21st century 14 Mar 02 http://www.ott.doe.gov/pdfs/jtb_ethanol.pdf PDF Impart says: Although E95 is a good fuel for buses and trucks, it cannot be used in standard diesel engines. So tests are under way to determine whether a new ethanol-based fuel can power such heavy-duty vehicles without extensive engine modifications. Called oxygenated diesel or E-diesel (E stands for ethanol), the new fuel contains 15% ethanol, 80% diesel fuel, and 5% of an additive that helps the components stay mixed together. This blend promises to significantly reduce exhaust emissions from heavyduty vehicles while helping to lessen U.S. dependence on foreign oil. Information Sheets and Fact Sheets with various listing such as - Henry Ford and Fuel Ethanol and a Biodiesel category. Canadian Renewable Fuels Association (CRFA) http://www.greenfuels.org/ethindex.html Ethanol Vehicles Operational Performance If compression ratio is optimized for higher octane rating, ethanol has approximately 80% or more of the energy density of gasoline. http://www.afdc.doe.gov/afv/ethanol.html Ethanol Performs (excerpt) "With a higher octane, increased compression ratios and more advanced timing curves can be used to increase performance. The increased compression ratio leads to greater thermal efficiency, which can increase gas mileage. A properly tuned E85 can get comparable gas mileage to its gasoline counterpart." http://www.kettering.edu/~technews/79-5/206.htm Fuel Chemistry A brief outline and easy to understand explanation: - Molecular Size - Incomplete Combustion - Oxygen Content - Carbon Content - Avoiding Carbon Dioxide Emissions Entirely http://www.altfuels.org/fuelchem.html Fuels and Society: "The Chemistry: Automotive fuels derived from petroleum propel our cars by converting the energy of combustion to heat and work. The challenge for an efficient, powerful engine is to maximize the work available. The second law of thermodynamics teaches this can be done by making engines with a high compression ratio. But problems of uneven fuel combustion and knocking must be overcome through fuel reformulation or by finding an appropriate additive." The History: Automotive designers and engineers had three choices for reformulating and improving fuels. Copyright 2001, Laurence I. Peterson and Matthew E.

Kennesaw, GA 30114 http://chemcases.com/fuels/ "Racing on Ethanol" http://www.ethanol.org/racing/racing_on_ethanol.html Excerpts impart plus more: Test results show that, if run properly, ethanol can give racers added horsepower and torque. Pure ethanol has an octane of 115, which is about the same as methanol. Gasoline has an octane of anywhere between 85 and 95, with low-lead aviation fuel coming in at about 100 octane. Gasoline contains no oxygen, ethanol is 35% oxygen and methanol is 50% oxygen. Ethanol, like methanol, will burn cooler than gasoline, and will allow you to increase your compression ratio when using it to replace gasoline. Although this site speaks more towards racing fuel Methanol then Ethanol (correction welcomed) you will be able to see the advantages & disadvantages.
