Thread: If anyone is interested....

Hi and welcome to the forum,

I can only tell you what I know about the E10 and I have used it in my '93 Disco without dramas. What others are using I only know from what I've read and that is that others overseas are using the E85 without problems.


Anyone else know any different?

Hi Pete, just realy interested in how your machinery is running on your ethenol based bio Diesel. I've been doing a heap of reasearch on both wvo and bio Diesel over the last 4-6 months to see which is the best way to go. The more info i get the more difficult it seems to make a descision. I've taken a interest in your system because it seems to be a cross between the two main alternative fuel systems, it's almost like running wvo and adding ethenol based alcohol to help it burn and flow better without the chemical seperation process that makes bio Diesel, also i'd be genuinly interested in in how that test injector is perfoming.
thanks, MIC.

Hi Mic,

All the machinery is still going fine, no problems with the colder weather so that's a good thing. I was supposed to have had the test injector up and running by now but haven't. Having said that, if you think about it the various injectors in the current list of machinery is pretty diverse so it's a test of injectors anyway.

Regarding the waste oil that you source, my on-going results are better/cleaner if you filter the waste oil first using a 10 micron filter, then "dry" the oil either by fast heating it to 140 celcius to get rid of any water quickly as steam, or to heat to 85 celcius over several hours and then let it cool. With the 85 method, you'll find that the water will "pool" on the bottom of your heated oil once room temp and you can decant your oil off the water that way.

Then process the oil with the standard 4g of KOH, 250ml 99.7% pure ethanol (Diggers or Durobond Methylated Spirits) to 1 ltr waste oil at 55 celcius. Don't forget to keep mixing the "mix" (I do 10 minutes per ltr) to get a good blend.

Once this is complete, you can filter this through a 1 micron sock filter into your storage tank. This filtering will remove particles down to below the injector specs which are 5 micron.

I've also yet to get the girl dyno'd on the eth-bd so I can post the comparisons on the petro-diesel dyno' results and the new ones. Will be doing it soon though as I've been asked by others to see the results.

Hope some of this helps.

Cheers, Pete'

where does one purchase KOH? in what qty is it available? at what approx cost? does it require any special storage? is it known by another name or generic term?
can anyone tell me which oils produce the nicest tasting exhaust pipe?

Hi,

KOH or Potassium Hydroxide aka Caustic Potash, is used in cleaning products so a good bet is one of your local cleaning companies (big or small), that make their own soaps, cleaning products, etc.

It tends to be in 25kg bags and you'll pay anywhere from between $50 - $125 for it.

I would suggest a plastic drum for storage but still keep it in it's bag as well so that as little air moisture gets to it.

Regarding waste oil, I get really good results from Soybean oil (ETA brand I think), but the formula should work with most waste oils.

Cheers, Pete'

This is all very interesting about using ethanol instead of methenol.
2 Questions I have,
Why do the main biodiesel manufactures go to all the effort to get ride of the glycerine? I have heard that glycerine burns at a very high temperature and doesn't get completely burnt in the cylinder of an engine and eventually coats the pistons, rings, valves etc for a messy ending to the engine down the track.

The 2nd question is if you are using 250mls / litre of Veg oil how do you make it in such big quantities. I make it in small quantities for drinking but would not be able to keep up in such a large quantity for running the car on. What do you make the ethanol from?

At the end of the day, it's always good to be independent from the dominating oil companies.

Hi SteelNerve,

Welcome to the forum!

Your first question refers to 'pyrolised' fuel and is really talking about SVO systems. Take a look at this thread for further info'. vegetableoildiesel.co.uk - Direct Injection and Post 1999 Vehicles.... - Powered by XMB

Your 2nd question is answered by the fact that I simply buy my ethanol in 200-400 liter quantities from industrial warehouses rather than make it. I did toy with building a reflux still but I drink enough as it is mate!

Cheers, Pete'

That's an interesting article Thanks Frontier.
So what he is saying is that the new motors through simple chamber design but complex injection won't burn WVO completely but the old engines will because of better chamber mixing and simple injection.

I have been mixing up to 60/40 Bio with Petroleum Diesel in my 300tdi to ensure a good thorough burn and to keep the pump clean and lubricated.
One more interesting thing to through in the pot is a LPG conversion. I understand the adding of LPG to the chamber helps burn the diesel from about a 89% to a 95-98%. This would certainly help ensure all of the WVO is burnt and not left behind to coat the piston rings.
More food for thought.
Cheers
