Durbans new experiment .parrafin & accetone

[durban]

ive tried almost any thing i could get my hands on to mix with parrafin except benzine , witch is very diffecult to get and not good for our enviroment thats why petrol companys have done away with it mixing it with petrol . i got my doctors syringe out & measured milliliters of parrafin off & accetone mixed it together put it into my 2stroke lawnmower pulled the rope start & it started fist pull & idled & increaced the rpm , so then i put the same mix in my 70hp & it started , now the next thing to do is get some oil & experiment with that . the cost of petrol makeing me look for an alternative

When you say paraffin, is that naphtha or kerosene?

Re: Durbans new experiment .parrafin & accetone

because thats the word i know when i grew up it Africa we call it parafin over there in the rest of the world they call it what ever .anyway comeing back to my story when i got the whatever to ignitie with a flint from a cigarette liter i knew a spark plug would do it too .[ kerosene]

Re: Durbans new experiment .parrafin & accetone

if i can formulate the oil to go with it countrys like Ireland will bennifit as they pay 10 cents a liter for parafin .

Re: Durbans new experiment .parrafin & accetone

Which brings me to the question of why the hell is kerosene so expensive in the US?

Re: Durbans new experiment .parrafin & accetone

at the same time this reduces carbon dioxide in to our enviroment cause it burns clean & lowers engine temp its got a very high igniteing i noticed this when i put some into a 4 stroke motor so the pre detonation must be avioded i will set the spark to as close to tdc when i go further with this project .

Re: Durbans new experiment .parrafin & accetone

there is nothing new about petrol engines running on parrafin.

just look up petrol parrafin engines, its been around before world war 2.
today some outboard engines are running on parrafin direct from the makers.

in a diesel lorry for example the parrafin is used but lack of lubrication to dueto the dryness of parrafin, so back
in the 1970;s when diesel was on a shortage my dad and me ran the lorry's on 5 gallon of parrafin and mix 1 pint of engine oil.
this gives enough lubrication and is pretty much what we know as diesel/gas oil....
the 1950's morris engines in boats were 50% of petrol and 50% of petrol parrafin engines.
the engines would start up on petrol, let them warm up and switch a tap over to run on neat parrafin.
There is also the tvo engines, tvo stands for tractor vapourising oil and is supposed to be only used for agriculture etc.
Many bus and coach company's still use today, the smell is horrible, and its illegal for road use but many still use it because its cheap.

YOU ARE ALLOWED TO RUN PARRAFIN IN UK BUT YOUR SUPPOSED TO SEND OFF MONEY TO THE TAX PEOPLE.

as for outboards there is many that are on duel fuel, and plenty that run on parrafin.

so nothing new there, and i dont know who told you parrafin is so cheap in ireland, its about 5 times your quoated price.

Re: Durbans new experiment .parrafin & accetone

i know all this they use them in india when i was liveing there i saw heaps the problem is that you have to start it on petrol first then switch over & running it on pure parrifin the motors do not last long either this is why iam going a little different to that by mixing oil with my mix where as they dont do this over there they just switch striaght over to pure parafin while its stil runs on petrol

Durban, nice to hear of your little experiment. I have queried using Kerosene before as over here as we use it for heating our homes. it's approx 1 euro a litre and petrol is currently 1.66. It may be 10 cents a litre but then the government heaps taxes on it and by the time we can get our hands on it it's around the 1 euro mark.
I'm told that you need to start on 2 stroke then switch over to kerosene, compression will need to be lower though so 2 head gaskets should be used. Also make sure to switch back to 2stroke before stopping as if Kerosene is in the carbs it seemingly is a b"@#h to start.

Meant to smell something horrid too which kinda put me off using it too.

Re: Durbans new experiment .parrafin & accetone

there are brand new outboards that come ready for duel fuel (petrol and paraffin/kerosene).
paraffin just burns at a higher temp than petrol, so do make sure you dont skimp on the 2 stroke oil.
yes paraffin also does create a bit more compression, but unless your on high compression you wont realy
need to lower it by using extra gaskets, but if the engine is a high compression ratio then yes the above about
2 gaskets is a very good idea to lower compression and will save the engine a lot of undue stress.

on some of the old cars that ran on paraffin they used to have the paraffin fuel line running alongside the
exhaust to keep the fuel temp high before entering the carburretor, ive been told this can help but not always
needed in summer months.
I think its was mainly for extreme cold winter months that the uk used to have back in the 1950's and 1960's

if you have a very modern outboard like the optimax where the oil gets inject you can use LPG/Propane once
engine is warm.

The only fuel that isnt realy upto the mark just yet is diesel without huge expense, but even yanmar do make still
outboards that are diesel.

Many people have forgotton about using parrafin as the engine fuel, there is not realy many drawback and can
save a fortune on fuel bills.
But the 2 stroke oil mixing with todays paraffin might be something that needs to be looked into.

But a test of mixing the oil should prove worthwhile.

Maybe an e-mail to an oil company could be usefull, just ask them what oil they would advise to use
on 2 stroke paraffin engines that are going to be used in marine enviroment.

Re: Durbans new experiment .parrafin & accetone

thanks for a bit advice phill , you see the advantage ive got is that it doesnt need petrol to start , it starts on its own mix , cause of the accetone , i know there are pepole that run thier cars on accetone mixed with petrol i found a forum on the net about that some time back , when you talk about high compression i agree with you case i put some in a four stroke mower too & it kicked some of the oil out of the side where the dip stick goes in it started , but being 4 stroke i had to pull it several times to start , now i dont know about the oil to much cause of the accetone i think if i put 2 stroke oil in with the accetone & kerosene in i may thin it out , so i was thinking more in the lines of sae 20 or 30 , i dnt know will have to experiment a little more once my rad con is finished . about the 10 cents a liter in Irealand i read it here on this site some time back there was some one that wanted to run his motor on pure kerosene ,

i read some where too that kerosene needs more heat to combust , so buy me mixing it with accetone surely then this does not aplly the fact that it combust with a flint from a lighter , but on its own its a battle to light it with just a flint without the flame , so i think the high copresion thing will fall out some where cause of the accetone in it , dont know your gess is as good as mine , cheers

well thats the indians for ya,have no idea about long term damage to anything including engines and people.
Any fuel that already needs an oil added will still need to have oil added,
Paraffin is a lot dryer fuel than even petrol when it comes to lubrication, so ofcourse their engines dont last long when
running on pure paraffin.
im suprised they last anything over about 10 minutes, but then most idian produced engines have such terrible tolerances they
probably never normaly get to proper running temps even on petrol.

tohatsu make 2 stroke duel fuel outboards, maybe their oil is the answer your looking for.
its not a new idea, it was being done over 60 years ago.

so i cant see anyreason you cant do it today.

This realy proves evolution, your just a few years behind a top scientist.
many times ive had a great idea and want to invent a particular thing that will make the world listen.
2 days later i see a secondhand version of the same thing on Ebay thats 50 years old ha ha ha

off the subject a little bit , in GOA surpriseing to see the amount of britsh biuldings & the old Triumph & BSA motor cylcels still running there thousands of them . cheers

Re: Durbans new experiment .parrafin & accetone

i can remember grandad telling me how they set fire to paper and wood under the old parafin tractors to heat the engine then pouring a little gas over a rag and holding that over the intake to get them to start in cold weather. wouldnt be hard to set up a motor for dual fuel so you can start and stop on gas but run on parafin as you only need a small container of gas. not realy sure how fuel taxes are calculated on a boat i know back in the uk a farm doesnt pay tax on off road fuel so you have to wonder if a boat should in the first place

Re: Durbans new experiment .parrafin & accetone

first of all to Durbal.
Yes paraffin can be lit with a simple flint, the old tilly lamps were paraffin and lit with a flint.
the paraffin mixed with acetone i dont think will be a good idea as acetone is not cheap and also not too good for
the steel rings in the engine.

Now the paraffin dont need anything else to get going once the engine is a a bit warm, i dont mean hot ,just started up.
the fuel pipe for the paraffin will be ideal if you route it as close to the engine as possible to keep it warm, the paraffin
will ignite much better and turn to mist better if warm.
The 2 stroke outboard oil is far better than the sae 20 etc as it dont capture as much moisture being tcw3 !!!!
it will smoke like a chimney with sae 20 or 30 oil in the fuel, the diesel lorry engines are prone to smoke bad when
engine oil is mixed with paraffin.
But like i say the paraffin is a very dry fuel and so is the acetone !!! i think you can forget about the acetone and
concentrate on what is the best opil to mix with the paraffin.

You like an experiment or two and have a good idea about many different fuels and compounds, i think youl find
a much better oil to mix and cheaper than tcw3 oil.

But half an egg cup of petrol weill be plenty enough to get the engine started then switch to the paraffin.

I think it would be an ideal fuel for motors like the british seagull, they were built to run on anything chucked at them.
But a modern high performance 2 stroke might be a bit weaker built for the paraffin in the long term......

To glen property of pamyes its very true about making a fire under engines in cold weather.paraffin and diesel.
i can clearly remember in the mid 1960's my dad getting a load of wood and setting fire to it under the engine to
heat it up to start.
this heat helped warm the engine oil, and de-freeze the diesel that used have a lot more water content than todays fuel.
When on paraffin it was the same,cold weather needed more heat.
Todays diesels have much better heat plugs to get the fuel going. without heat plugs even todays diesel wont start easy.

When you put a burning rag over the intake to help it fire it makes a huge bang and scares the life out of you trust me.
Ford A series and early diesel transits you had to hold in a button on the heat start and wait for an explosion then turn the key.
I used to get my mates to hold up the bonnet on a van i had and ask them to listen to see if anything was wrong, when it went
bang they would be scared out their skin ha ha ha

Re: Durbans new experiment .parrafin & accetone

Search outboards used by US Navy, and Seal teams, carriers only carry Jet fuel. Evinrude was making a multifuel engines for the Navy, don`t what happen. I may have a parts microfitch for a kerosine Evinrude, will check in a few days.
