This study done by Pure Energy Systems shows that adding Acteone to a tank of gas can improve mileage dramatically.
How it Works
Complete vaporization of fuel is far from perfect in today's cars. A certain amount of fuel in most engines remains liquid in the hot chamber. In order to become a true gas and be fully combusted, fuel must undergo a phase change.
Surface tension presents an obstacle to vaporization. For instance the energy barrier from surface tension can sometimes force water to reach 300 degrees Fahrenheit before it vaporizes. Similarly with gasoline.
Acetone drastically reduces the surface tension. Most fuel molecules are sluggish with respect to their natural frequency. Acetone has an inherent molecular vibration that "stirs up" the fuel molecules, to break the surface tension. This results in a more complete vaporization with other factors remaining the same. More complete vaporization means less wasted fuel, hence the increased gas mileage from the increased thermal efficiency.
That excess fuel was formerly wasted past the rings or sent out the tailpipe but when mixed with acetone it gets burned.
Acetone allows gasoline to behave more like the ideal automotive fuel which is PROPANE. The degree of improved mileage depends on how much unburned fuel you are presently wasting. You might gain 15 to 35-percent better economy from the use of acetone. Sometimes even more.
Only in the sense that carburated systems usually have almost no pressure in the fuel line, and only about 3psi between the mechanical fuel pump and the carburator, while FI systems usually run a somewhat higher pressure from the tank to the injection system, and between the injection pump and the injectors, I've seen pressures anywhere from 30 psi to as high as 500 psi.
It's the fuel line pressure, not the fuel delivery system, that inhibits vapor lock.
The point is that regardless of whether the car is carburated or injected, reducing the vapor pressure of the fuel increases the risk of vapor lock, and that's exactly what they seem to be claiming the acetone is supposed to do.
IF what these guys are claiming were true, then everybody in the Northern US ought to get MUCH better gas mileage in the winter, because petroleum companies change the mix in winter months to have more low vapor pressure components to facilitate starting, and that's exactly what these guys are claiming the acetone will do for you.
So who here is getting a 25% increase in fuel mileage in the winter? Not me.
Lastly, if adding acetone improves mileage so much, and has no deleterious effects, then why hasn't a patroluem company added it to it's gasoline at the refinery? After all, a 25% increase in mileage over their competitors' gasolines would make for a very attractive sales advantage, wouldn't it?
The answer is left as an exercise for the reader....
A ceramic engine could run at a higher temperature. There are other metals than aluminum and steel also. The Russian rocket motor assembly that is used in the Atlas rocket series is very efficient, some claim it is the most efficient large rocket motor commercially available. That motor is very hot as can be seen from the blue-white color of the exhaust.
Hmmm .... so arsenic or hydrogen cyanide dissolved in acetone makes a squirt gun a deadly weapon.
FINALLY something street legal for england home defense :)
Thats why V8's can use higher octane, that is unnecessary in rice burners...
Is that in cars or scoots?
There are only certain plastics that Acetone attacks violently. One of the big ones is ABS. You can actually use acetone as a glue to reattach broken ABS pieces.
It can't hurt; whether it measurably increases mileage would cost about $5.00 to find out along with careful measurement
That shouldn't be a problem for me. Both vehicles have new engine builds. Except for the blocks themselves. But I'm still a bit wary about it
Um...you are mistaken (and apparently chose a bad moniker).
Acetone does not cross tissue membranes like that. Think about it, millions of women and beauty care professionals would have been dead long ago.
Your thinking of DMSO - completely different and not flamable.
Nitrous oxide is not illegal and not combustible; it just has a lot of happy oxygen molecules that love to play around in a big bathtub of gasoline.
Driving downhill increases gas mileage by 50% to 75%
So, DR, OCG, are you folks stating the acetone may not offer mileage enhancement if one is already using a higher octane fuel, or won't help if someone has a V-8?
Would you be suggesting only lower octane fuels that "explode" be utilized with a blend of acetone?
I admit - I'm confused.
Shhhhhhhh.....Price of Acetone may increase to $55 a gallon.
Not when added to gasoline and kept in suspension/partial solution; the oil companies already add a small amount.
And just what is this supposed to mean?
It can't keep its legs still?
Vapor lock is a phenomenon associated with carburetors as they have shut-off valves; ECM engines distribute fuel at 35-50 PSI and rout back to the tank any unused fuel so there is no air space in the delivery line.
Carcinogens are highly over-emphasized; dose and application are the keys. Don't drink it, don't breathe the fumes and don't rub it into your skin and you'll be just fine.
From reading the article, the acetone is to enhance the atomization of the injected fuel, which is independent of octane's properties of retarding combustion.
