Default Nitromethane evaporate?

Does Does Nitromethane evaporate?

i found a way to separate the oil from glow fuel via evaporation. i was planing on using what i hope to be just methone, to run my spark ignition engine. so if anybody can tell me if i would be left with nitro & methane or just methane would be great

Well 2009 got of to good start.This is closer to how long is peice of string .When you let methanol evaporate and reform you risk to gain a high mount of water from the atmosphere.This extra water will make a mess of figuring out what fuel you have as now you can maybe have 105% of fluid when you measure the final results.

Assuming that you found a way to evaporate the methanol catch it with no water ingress then its simple to measure the result.Wiki links searches for Methanol, Nitromethane and lubricating oil will tell you the specific gravity of the different fluids.
(Also there exists this useful program HBBUDDY you search for it or go to post no.184
http://www.rcuniverse.com/forum/m_19..._8/key_/tm.htm
The HBBuddy program can tell you fuid onz grams specific graity whatever your fuel mix is)

So if you know your fuel you stated with was 20% oil 20% nitro methane and you find your 60% methanol is the evaporated beaker then you are probably on target.Too much more than this risks to include nitro methane Nito methane is a parrifin heavy type fluid with a high vapour temperature so dificult to ignite .probably difficult to evaporate.

But methanol is one the easiest cheapest ingredient to get hold of.Even in euroland where prices are high some $15 a gallon in the USA its often available for less than $5 a gallon .

Also lots of spark ignition engine prefer to use more easy to hold of E85 fuel which is 85% ethanol(very similar to methanol) and 15% gasoline (petrol benzine ).It could be interesting if you get the ~14% petrol out of Ethanol to make a more pure 99% Ethanol engine which might be more interesting than E85

Lots of threads on RCUNIVERSE converting spark ignition to run on glow plugs using methanol ethanol gasoline mixes

Have you a explanation diagrams and pics of your evaporation solution to see if others on the forum can comment if its working properly

thanks for the info. i think im better off with ethanol maybe even make my owne [link]http://running_on_alcohol.tripod.com/[/link] cause i want a fuel sources that i can get locale. i dont have any pic of the evaporation setup but ill make up diagrams to try and explain it as best i can.



basically the fuel evaporates then condenses to the concave lid, runs down to the center and drip into the container in the middle

Ethanol looks to be a good bet .Its works well with spark ignition and very similar to gasoline .It will probably supply 10% more power than gasoline but maybe 10% less than Methanol .However unlike gasoline it doesn't have lubrication qualities so instead of say 3% lubricating oil for gasoline Ethanol will often be 10% to 20% similar to methanol.Also the lubrication has to be the types that mixes with alcohols and these tend to be more costly oil.Suitable Castor oil exist and synthethic .They can be shipped to you without to be HAZMAT costs.The Ethanol should work well without nitromethane .Getting nitro methane pure through the post is a issue as it usually requires hazmat rates like methanol usually does.If you do go to use nitro methane 5% to 20% can help a lot same as methanol.

I think OS are bringing out engines that are made to run on ethanol E85 which should work OK with 100% ethanol.However before comiting yourself to Ethanol over methanol look in the area for the two fuels >paper mills and soap factories or paint factories often have one of these fuels and might sell it to you and save the problem to make it If your planning to run your car on ethanol that makes using ethanol production more interesting with larger scale production.

What engines makes and types you want to run on methanol or Ethanol.

believe it or not i plan on running my t-maxx on methanol.... dont worry its not the little 2.5 engine your thinking of lol.its a saito fa40a i managed to fit into my maxx so another thing im worried about is heat cause i know petroleum burns hot compared to methanol so makes me wonder if ethanol burns hot? if everthing works out ill be posting videos & pics here [link]http://www.rcuniverse.com/forum/m_8209410/mpage_1/key_/tm.htm[/link] if anybod is interested

Methanol and Ethanol generally burn cool compared to gasoline fuels.To burn gasoline often bigger cooling fins or extra cooling is required .Also the engine burns more volume of Methanol or Ethanol and this also acts to help cool the engine

Methanol soaks up an enormous amount of heat when it vaporises inside the engine, roughly 10 times as much as petrol does, which is why methanol powered engines don't need as much cooling fin area as a petrol engine.

[link=http://www.holdfastmac.com.au/techcharts.html]Here's[/link] a chart from the web page I do for my club that lists the physical properties of most fuels.

just what i needed that explains a lot. according to that chart ethanol burns hotter than methanol but not near as hot as petrol so i think with adequite cooling (fans and what not) i sould be ok

Methanol also doesn't burn as hot, yes it gains more heat in the crankcase, cooling the crankcase, but it also burns at a much lower temperature.

You can heat the fuel and distill the alcohol. You can do this without gaining any appreciable amount of water, and if you pump out the air thus reducing the amount of heat added you will reduce the amount of water in the fuel. Nitro evaporates at a much higher temperature than the methanol so just keep the still well below the boiling point for nitromethane and you will only have a trace amount of nitromenthane.
