Thread: sump oil

Didn't think it would be!

Was thinking about this today whilst at work.. Re the sump oil... No. That's a given! What I was thinking about tho was the burning of wood to make fuel... Most of the pics I've seen of home made smoke producers to run engines are very basic... and most of the fuel is probably soot, but, having been part of a Compartment Fire Fighting course a month ago where I was in a 40' shipping container watching fire behaviour, got me thinking. When wood reaches the pyrolysis stage, gas is given off... around the 400deg mark. To get this flammable vapour at a continuous flow would take quite a bit of control. If this could be done, Am I right in thinking that the soot amount would be minimal as its gas that's given off.. (This very same gas that is so volatile when fed with oxygen causing flashover). For those who have not seen flashover, check it out on YouTube, quite interesting, especially in America where smashing the window of a burning house and pointing a fan into that newly made hole seems to be a good plan!!!! By the way, its not! Think I'll stick to my cooking oil filtration, its easier!!

You forgot to quote my last sentence.

Would I use it in my Disco? Probably not.

From all I've read and and understand you could use it successfully in a TD5 ......I'm sure that was part of the engines original specs... that it was to be able to run satisfactorily on almost any combustible oil of suitable viscosity.

And suitable cleanliness.

The TD5 was tested on Kerosene.

The high injection pressures / nozzles don't like 'dirty' liquid.

You can see that this conversion has a huge cyclone after the furnace to remove particulates.

Filters and scrubbers are usually also used.

However even with all that wood gas engines have a lot of problems with particulates.

Well lots of stuff on Google on using waste oil.
Seems the use of a centrifuge is better than filtration.
Can buy one from the U.S. but does anyone know of any being made on OZ.

With vege oil getting hard to find it seems waste lube or ATF is the go.

I have been looking at these for a while , I think you can get them for around $600 in the US .
Can anyone with a genuine knowledge on the subject please tell me ...If sump oil from your average 300TDI can be safely used as an additive in the diesel tank [ at the appropriate rate ] if treated properly with one of these centrifuges ?

Some time ago many US fleets had a filtration and blending plant made by Racor that separated moisture, filtered, and blended used oils into the bulk distillate supply at a ratio chosen by the operators. Their clean air laws put a stop to this although I am sure many operators just kept on doing this while they could. After all, a gallon of used oil burnt in the engine was $3 in the pocket.
