Alternative Fuel

10/16/2009 7:04 AM

I've tried Straight Veg Oil using a Ellsbett conversion in my Volvo V40D (Renault Engined) but had problems with the piston rings getting gummed up. I've now removed the conversion and running on Diesel again, but with prices rising I was wondering...

Would it be ok to run the engine on used filtered hydraulic oil or a blend of Hydraulic oil and diesel? I've already mixed Hyd oil and diesel 50/50 and they do not separate.

Anyone have any ideas?

Cheers

It's the glycerin in your SVO polymerizing that causes your piston rings to gum up. To burn it, you'll need to tranesterify it into biodiesel.

I don't see that the user group ever became formalized?

I have a few tricks to share since I'm no longer in production.

I didn't see harm in giving the group a plug

I'm mixing #2 fuel oil with soy at 80/20 and hope to note less sooting of the heat exchanger this boiler using season. The addition of soy increases the cost but significant reduction of soot may benefit efficiency to break even.

I know this is out there, so don't beat on me bwire. Sooting is a symptom of incomplete combustion, right? Well, adding a catalytic converter to the combustion chamber may be too complicating, but I've been reading about HHO combustion in cars, and I think it burns hot. How about adding HHO to your burn to raise temps to burn up your biofuel? It's easier than plasma.

Good question but it isn't the biodiesel that's causing soot it is the #2 fuel oil. I'm adding soy oil to the fuel oil in increasing amounts and as this soy oil percentage increases the amount of sooting will fall off, thus increasing the efficiency of the heat exchanger.

I'm thinking use of a CAT would be difficult to employ in the combustion chamber of the boiler. Are you familiar with one piece combustion chambers in oil fired HW boilers? The oil is sprayed into the chamber under high pressure then ignited immediately under the heat exchanger, where to use a CAT?

That's the thing. To use a cat would mean a whole new combustion chamber, lots of work. For the cat to be before the heat exchanger, you would need a whole new combustion chamber, then the cat, then the heat exchanger. I'm not even sure a cat would work for biodeisel; they are used for gasoline cars, but are they even used on diesel cars? I've seen them for wood stoves, after the firebox, on the stovepipe.

About that plasma...it's used for burning trash, hot as hell. How much trouble is it for the average consumer? I found this one site for a plasma spitting spark plug, but it was experimental.

Unfortunately the group was never created. I guess the threshold needed never was attained. To bad.

I have started my third year of winter production of biodiesel used to heat my 200+ year old house. I am interested to hear what some of your tricks are.

Stay warm

Buy a cheap breathalyzer to check your work area or bio for methanol. Make sure you don't have to blow into it. Methanol eats your optic nerve; it's not uncommon to meet homebrewers with deteriorated vision...

If you are using amberlite or other dry wash, you have to be aware of the water content since water yields soap. Soapy bio run-through amberlite lowers the ph of the finished bio.

Tell me something about your processor set up: what is your method of heating?

What kind of mix times?

For Marcus:

Try this link to what many think is the best Bio forum

I didn't read all the posts. You can do it as long as you get viscosity close. The emissions will probably be a bit worse (zinc & sulfur, to name a couple).

Small amounts are probably not a problem. If you are going to be using a lot you might want to do some compatibility tests on hoses & seals.

You can always try a 200:1 mix of 2 stroke oil (Non Synthetic) in your fuel load to improve the performance of the fuel.

There was a study done by Mercedes Benz during one of their endurance testing trials(Berlin to Moscow) which provided good results, with no harm to the engine or catalytic systems that are required for euro epa regulations.

Also improved performance and economy reduced the soot load. As well as lubricating the injector pump, very important with low sulpher diesel. It also makes the engine quieter on startup.

Not sure about running hydraulic oil, in a modern diesel. Older diesels with inline pumps will be happy to run on just about anything resembling diesel (even straight kerosene/ Jet A1), but modern high tech diesels are a bit fussier.

Running veg oil (WVO) with the 2 stroke oil (non synthetic) as an additive would probably help you in the long run.

There was a thread on ih8mud forum in their diesel section about it.

Send me the conversion I'll glad to make it work then send it back

How about you tell us the mil spec of the hydraulic fluid first?

The gummed piston rings come from the glycerine and byproducts that you have to remove from the crude vegoil and produce biodiesel.
See this in Google: glycerin and biodiesel, http://www.biodieselmagazine.com/article.jsp?article_id=1123

and http://www.esru.strath.ac.uk/EandE/Web_sites/02-03/biofuels/what_biodiesel.htm

Once the reaction is complete, two major products exist: glycerin and biodiesel. Each has a substantial amount of the excess methanol
