The idea is to get into running one with 100% renewable sources. No petro or coal, including biodiesel unless it can be made with no use of fossil fuels. Part of this is just to see if it can be done.
Doug: I plan to use canola oil as the lube oil. Castor oil made a great lube, but, it always left behind a residue that had to be cleaned out. The reason is that it, like Linseed oil it oxidises easily, due to the presence of linoleic compounds, which is why they are so great for oil base paint. However, Canola, peanut, and olive oils have oleic compounds which don't oxidise easily. That's why the guy was able to run it as lube oil in his truck, also why they are so good for frying. They can take the heat so to speak. Yes the earliest automatic transmissions were a whale oil base, not petroleum, because it could handle the high temps as well as the high pressure. They had a real time coming up with a suitable replacement from petroleum base oils.
rcavictim: Whatever with the thinning/molecular reaction. The thing is that it enabled a thick vegetable oil to combust better in an engine. Same thing as the guy using ULG to aid in combustion. The price of the turpentine is still to be determined. By the way I live in Florida which is where much of it comes from. Since the Listeroid doesn't carry the high bearing loads that high speed engines do the pressure problem should be better. Running the used lube oil into the IP as fuel would be the object. Length of time as lube to be determined. Every shutdown OR day drain off a 1/2 cup or so into a small jelly jar (or other clear container) and allow to cool off then check for viscosity or gelling. At the point that it just begins to start getting thicker or at the regular recommended change interval, drain the oil, clean, filter and put it in its' own tank. Warmup on VO, switch to used VO tank until it's burned up, then back to VO tank. One strong possibility would be to have a small pump injecting a small amount of new SVO into the crankcase, then another small pump pulling the same amount out of the crankcase and into the injection system on a continuous basis (after filtering,etc.). Wouldn't pay to put it onto the new SVO tank due to possible contamination issues.
Of course I will need to work out how to keep the engine running well on SVO. I plan on changing the CO valve to a heating type unit which would run continuously. Keep the higher compression and run a glowplug in the intake to heat the incoming air for engine warmup. Run the exhaust into a biomass trench to take out the particulates and Nitrogen oxides. Of course this might mean that using the turpentine wouldn't be needed at all. Maybe a method of running could be developed that could be modified to use locally available fuels. Oh, might even try using the SVO as the coolant also, better heat retention in the combustion chamber for better combustion.
captfred: I'd be interested in finding out more about that plant oil cooker you were talking about.
