Acetone as fuel addtive? Any real information?
Acetone as fuel addtive? Any real information?
(OP)
Does anyone have an real information on acetone as a fuel additive? Please don't search the web... most references lead back to one single person's testimonials.
My interst focuses primarily on thinning waste vegetable oil to run in my diesel truck.

Cold weather is acomin' and improved "weatherizing" veggie oil could help promote a hot grass roots movement.
A fellow by the name of LaPointe is a big proponent of acetone as a fuel additive for vehicles, and so many website reference his claims.
It reminds me of the patient who asks, "Doctor, I'd like a second opinion!" The Doctor says "OK, I'll guess again."
RE: Acetone as fuel addtive? Any real information?
There is no sound engineering basis for the use of acetone, and there has been no engineering study that confirms the effectiveness (!) of using acetone as a fuel supplement. Any "by the seat of your pants" testing is just that, something that passes by the seat of your pants!
Those websites that bark the holiness of using acetone, and that just an ounce in 20 gallons will double your fuel mileage have never submitted their studies for serious engineering peer review. This is something which all engineers must submit to, peer review, and each study must be repeatable in order for it to be valid.

Diesel fuel and petroleum-based lubricant basestocks may have poor cold flow properties due to residual wax (n-parrafin) content. These waxes crystalize at low temperature forming a gelatinous network with the fluid. Specialized polymers are added to the fluid to control the shape and size of the crystals which reduces the gelling tendency.
Vegetable oils will have no wax content, and so probably won't respond well to traditional CFIs because their flow properties are due to the inherent characteristics of the esters in the fluid. This also makes them a harder cold flow problem to crack. Any low melting fluid such as acetone that is blended in will thin it, but it will probably require much more than an "additive" treat rate (i.e. >>1%) and so affect combustibility and possibly equipment hardware.
I don't know how compatible acetone is with diesel combustion, but I have seen papers suggesting the use of certain low-molecular weight ethers as diesel fuel additives (cetane improvers?), so those must be compatible to some degree and might be another option to research.
Also, consider acetone and ethers will be prepared from petroleum sources, so the more you need the less "green" the biodiesel is.

Acetone also azeotropes water and acts as a dehydrating agent. The acetone water azeotropes isn't miscible with a lot of materials.

Lots of good info.
Have a nice day, Tom
