- The idea is that the oxygen in the ethanol (or methanol) is more reactive
- than the oxy that gets pulled out of the air, lowers the combustion temp
- (not so that you'd really notice), and helps the gasoline hydrocarbons to
- burn more completely, especially on those short drives that don't allow
- your engine to heat up to peak temp (especially this time of year). If the
- gasoline was to burn completely, the only by-products (emissions) would be
- CO2 and H2O (in the form of vapor), like alcohol.

- Actually, it will reduce your "organics" (hate to tell you this, but CO2
- is considered an inorganic-organic molecule) if your engine is running
- right- if your HC's go up, then that means your engine is in need of at
- least a tune-up. The laws of organic chemistry sez that methanol or
- ethanol plus gasoline plus air ignition source cannot equal more HC's than
- gasoline plus air plus ignition.

- Nope. The laws, if anything, have required that HC emission levels have

- Yes, ethanol costs more. Methanol costs about the same. However, liter for
- liter, methanol provides a 66% better oxygenation curve than ethanol, so to
- achieve the effect of 10% ethanol, you only have to have 3.3% methanol.
- And methanol is far cheaper to manufacture and purify, along with no
- federal taxes on it's production (p.s. it can be made from corn stalks,
- wood shavings, sawdust, hay...etc- anything that contains cellulose or
- vegetable fibers)

- Sorry, Bill- It may not "clean" up the air- only an ionic exchange unit
- can really do that, but it does lower the emissions that spew out of
- exhaust pipes. Especially the toxic ones. I don't know that your info is
- all that good, either. To give you an idea, a vehicle that runs purely
- upon ethanol or methanol would put out NO HC's or CO- only H2O and CO2,
- both substances that are naturally occuring in the atmosphere in large
- quantities. At least I'd much rather be inhaling them than CO or HC's.
