Better chances at passing emissions

[jess p]

Adding 1.5 to 3 ounces of pure acetone to every 10 gallons of fuel will:




1) Cut your emissions by half
2) Improve your gas milage considerably
3) Improves performance.

Do you have any data to back up these claims?

4) It will eat your rubber fuel lines.

The statement is obviously bullpucky just by looking at the physics of it.

#1 - It is technically possible that something could effect the burning process to increase the cleanliness but with no proof... All I can say is this is what he is trying to infer is true by using the other statements as support. So lets look at the other statements.

#2 - To increase the gas mileage with an additive it must either increase the quantity of BTUs per gallon by a notable percentage or make a major change to the basics of the Otto cycle. This claim falls on its face... hard...

#3 - The response to this is basically the same as #2.

The end result is BZZZZZTTthankyouforplaying.


Oh and #4 sounds spot on.

Eating beans always helps me pass emissions.

Acetone improves surface tension. It does not eat rubber fuel lines. Additionally, it
burns hotter!

Some interesting reading here about the subject.

Previously failed emissions with 2200 HC, co was at 6.1. I added 1 gal of regular
gas and 17cc of acetone to the tank. Drove back to the emissions station and re-tested. PASSED!
The results were 1200 HC and 4.23 co. My motorcycle seemed to run better as well.

You are correct that acetone does reduce the surface tension. However, it also eats most synthetics. This was on Mythbusters. http://kwc.org/mythbusters/2006/05/episode_53_exploding_trousers.html

Carburetor car: * Baseline: 17mpg at 35mph and 25mpg at 55mph * Magnets: exactly the same as baseline busted * Acetone: 16.7mpg at 35mph and 24mpg at 55mph busted * Super carb: much worse than baseline, 12mpg at 35mph and 17.7mpg at 55mph busted

Fuel-injected car * Baseline: 19mpg at 35mph and 27mpg at 55mph * Magnets: 18mpg at 35mph and 26mpg at 55mph busted * Acetone: 18mpg at 35mph and 26mpg at 55mph busted

Acetone will eat most plastics and synthetic rubbers. I know, I use to work at a plastics factory and one of the tests we use to perform on our plastic was to soak it in acetone to see how the plastic broke down over time ("how" it broke down was very important to QC.) Most seals in your fuel system are made of synthetic rubbers like around your fuel pump and sending unit in your tank, any rubber fuel lines and your seals around you injectors. And lets not even mention that most of the injector's body is made of plastic!.

Things that dissolve rubber:
bleach
kerosene
formaldehyde
aircraft paint stripper
acetone
turpentine

and the answer is....

acetone. it takes some time, but i just let the thing soak in a jar of acetone for a few days, scraped a little more out, soaked some more, scraped out the rest. didn't really dissolve it as much as it just made it spongey and fragile. might have completely dissolved if i left it in there for a month or something, who knows. i might have had better luck with a different solvent too, maybe toluene.

At 12-15 cc per gallon of fuel it's NOT going to dissolve anything!

[Mr.Puff]

Ok, I'll take your word for it.

acetone, do you mean the stuff ladies use for their finger nails?

at 6.1% CO and being gasoline has a HC ratio of 1.85, I see this as you are running WAY FAT.

I would opt to try and get my tune to be more stoichiometric…..
