How does ethanol work in a chemical perspective when it is mixed with petroleum to be used as fuel?

I’m writing a research paper on this and I need sources so if you look up anything, then please include the source. If you know something about this topic, then just go ahead and post it.

    Well, ethanol is a hydrocarbon, so the combustion reaction is:

    2C2H5OH + 7O2 –> 4CO2 + 6H2O

    This reaction produces a lot of energy. If an engine is created for ethanol use, it can utilize that energy in a cylinder just like a normal engine.

    i know alcohol slows down the burn on the gasoline and that ups the octane rating and that adds compression also the addingof alcohol makes the fuel burn the water thats incidental to the tank it makes it burn off until its able to be clean out of the system they are driveing cars around now that can burn 90% ethenol good luck

    how can you mix alcohol and petroleum in the first place? They are immiscible substances since alcohol is polar and petroleum is nonpolar.

    Ethanol is used as an "octane extender". So many companies put ethanol into their gasoline to lower cost. It burns according to common combustion reactions. It is a unique chemical in that it can dissolve in both polar and non-polar substances. this allows it to dissolve limited quantities of water in the gasoline. However, one drop too much water in the gasoline and there will be a phase separation where all the water as well as all the ethanol will separate from the gasoline and that of course would be bad. It is now being used to replace MTBE which also increases octane but MTBE is outlawed by the EPA.
