Re: [biofuel] Ethanol compression/mileage
You don't have to raise the compression to run ethanol but you can if you want to. You can run a higher compression ratio using ethanol especially if your engine has an aluminum head. The aluminum head dissipates heat much quicker and allows a higher compression ratio even with cast iron heads. I use to build racing engines for many years and never saw a head cracked from heat while running alcohol, at least none that I had built. If you live in the states and watch drag racing on TV you will see the cars that are running alcohol need more time to warm up. They are running aluminum heads and alcohol fuel(methanol). Ethanol is not that much different. The only thing you may have to do different is enlarge the carburetor jet size. If you are running 15% or less of ethanol with gas, you shouldn't have to change the jets but it could be different for different types of automobiles.

I am going to convert an old motorcycle of mine to E-85. I was told that I should raise the compression but didn't knwo why. Can you explain it to me? Thanks! ~~~Raising the compression ratio increases an engines' efficiency. When running alcohol as fuel, it is possible (and advisable) to use a higher CR. Alcohol has a much higher 'octane' rating than gasoline as well as a better quenching effect in an engine. The draw backs are ethanol has a much lower vapor pressure than gasoline, thus making cold starts on pure etoh difficult. Since I see you want to use e-85, that won't be a problem (thats why they blend gasoline with etoh, as well as to make it undrinkable). Alcohol has much less heat energy per gallon than gasoline so mpg suffers. Though this is partially offset w/higher CR. But if you raise CR to optimum for alcohol, you will be unable to use gasoline, as it will 'spark knock' and destroy the engine eventually. Then there's the problem of the vehicle weaving all over the road from too high a level of alcohol in its system ;-).
