The truth about the fuels Acetone and Ethanol
By Steve D. Gage
A report of independent testing, done January through
June of 2008.
My thanks to Mr. Louis LaPointe, who was brave enough to begin the Internet controversy over the use of alcohol and acetone as fuels or fuel additives. If it were not for his guts to publicly challenge the government, oil companies and auto manufacturers,
I would have never known, or even investigated what he proposed.
Based on Mr. Lapointe's writings and data on the Internet, there truly are ONLY two possibilities:
1] Any or all of the entities mentioned above do know the secret to clean emissions AND high MPG, achieved SIMULTANEOUSLY and are withholding it, in order to make more money off the public.
2] All three entities are too stupid to figure it out.
That debate belongs in another arena, not here.
I am simply reporting the data I have uncovered
and tested in the last few months, which gave
Both acetone and ethanol molecules contain one atom of Oxygen and 6 atoms of Hydrogen. They are both considered as "Oxygenated" fuels, because of the Oxygen atom in both.
Ethanol is mandated by the Federal Government to be used as an additive to gasoline in order to lower emissions. The decision as to this being done, and at what percentages of ethanol to add is left to individual states.
It is a fact that ethanol lowers emissions. The explanation for this effect being the Oxygen atom in the molecule.
Both Acetone and Ethanol have incredibly high EVAPORATION rates. Gasoline has a low evaporation rate in comparison.
All liquids evaporate at different rates.
When a liquid evaporates it COOLS the air it is in contact with. This is why when on a hot day, if you get close to a stream or river, you will feel the air temperature drop around it.
When air is cooled, it CONDENSES.
Via the EXTREME cooling of the air going into the intake of an engine, by both Acetone and Ethanol, MUCH more air in pounds is taken into the cylinders. Condensation of air means more of it is compressed into each stroke of the intake.
This results in a LEANER mixture of fuel:air in the combustion.
This leaner, highly Oxygenated mixture is what actually causes a drop in emissions of Hydrocarbons and CO.
Simply adding either Acetone or Ethanol will result in worse and worse MPG. This is caused by the extra O2 in the fuel:air ratio. The more you use the more the MPG will decline.
The idea that simply using ethanol is good for the environment, and creates less emissions, is INCORRECT. The strongest ethanol fuel on the market is known as "E85". It is 15% gasoline and 85% ethanol. Yes, it reduces emissions, BUT GIVES 20% LESS MPG than gasoline, thus giving an overall reduction in emissions PER MILE, which is near null.
Acetone produces much greater condensation of air than Ethanol, via the faster evaporation rate, thus MPG drops MUCH faster as the percentage of acetone(Oz):gasoline(Gal) is increased.
The negative effect on MPG of both Acetone and Ethanol, can be REVERSED, in order cause an INCREASE in MPG over gasoline, with acetone being needed in much smaller amounts than ethanol, and at much less cost.
[The potential increase in MPG of Ethanol has not been tested by me]
Test results from January to June, 2008:
Test car: 1985 Ford T-Bird 5.0L V8
Epa MPG rating: 15 city, 22 highway.
Emissions test using pure 87 octane gasoline resulted in Hydrocarbons of 190ppm at idle. Fail is 220ppm. O2 was 1.5%. This was suggestive of a small exhaust leak, which the O2 sensor read and richened fuel:air ratio a little too much.
Emissions test using 1 oz of Acetone to 1 gal. of gasoline resulted in Hydrocarbons dropping to 111ppm at idle. O2 at 1.5%.
Hwy. test with this mixture resulted in 23.5mpg. According to data on the internet, at this very high amount of acetone, MPG should have dropped far below factory. That it actually got slightly better than factory gave away the secret. The slight exhaust leak had richened the mixture of fuel:air and caused a SLIGHT utilization of the acetone.
I saw that the O2 sensor played a part in my results. What I did next was create an INTENTIONAL slight exhaust leak, in front of the sensor to increase O2 in exaust, to cause the computer to richen it even more. [leak causes sucking in of fresh air].
Emissions test resulted in increase of Hydrocarbons from the previous 111ppm to 144ppm at idle. O2 went from 1.5% up to 5.2%
Noticable increase in HP of at least 25%.
Multiple hwy. tests revealed 45mpg.
This is slightly more than a 100% increase over factory.
Tested at .7oz. per gal. MPG went down to 41mpg.
Tested at 2 oz. per gal. MPG went down to 30mpg.
By process of elimination, the best acetone mix for my current fuel:air richness is around 1oz. per gal.
The secret, known to racing technology, banned and forgotten half a century ago, is that fuels such as acetone REQUIRE richening of the fuel:air mixture to make use of them. It is said that in those early days of racing, some used as much as 10% acetone additive. I am using less than 1%. Specifically 1:128.(Oz)
With my emissons at slightly cleaner than gasoline, but my MPG at double what it was, a REAL REDUCTION IN EMISSIONS has been achieved. Fully 50% reduction.
The recent G8 summit set the goal of reducing emissions by 50% by the year 2050.
President Bush has signed in to law the requirement for vehicles to get 37mpg by 2020.
We have the technology RIGHT NOW to achieve this IMEDIATELY.
Reprograming auto computers is already possible and programs and devices are on the market to do so.
A simple solution for the do it yourself mechanic, until the use of the technology becomes afordable, and the additives are at the pump, is to TRICK your O2 sensors into making the computer richen. This can be done by either creating an exaust leak in front of the sensor, or by removing the sensor from the exhaust and letting it read pure aptmosphere, which is 20.9% O2.
The latter will richen mixture to MAXIMUM allowing the most acetone possible and the most HP AND MPG. I have not tried the latter and do not know how well it would work or to what level of increase in HP and MPG might be possible. Try this at YOUR OWN RISK.
New vehicles will FAIL EMISSIONS TESTS if too much O2 is reported by the computer. So make your exhaust leak sealable and reseal it for your test. If you remove sensor, simply replace for test.
Environmental impact of acetone is far less than an oil spill.
Brand I used is Kleen Strip.
I have tested no other brand.
