Unless you could filter out all of the carbon particles it would be like pumping grinding paste through the injector pump and Injector nozzles. I think if you could get the abarsives out for reasonable cost it might be feasible, but if it hasn't been done commercially by now there must be a good reason, regards Frank.

Want to chip in ?, buy one of these plants , waste oil and plastic bottle donations gratefully received

Plastic to Diesel Process,Waste oil and Plastic to Diesel

hmmmm I'd take a bet that the red tape required from local councils, state agencies and federal licenses would be piled so high you probably wouldn't get ever get approval to set up such a plant. I'm also sure that with a 6million litre annual production that the major oil companies are going to somehow put stumbling blocks in front of you. The concept is brilliant, why aren't these plants popping up?

Filter then Centrifuge the waste oil, then run through a normal fuel system filtration system and preheated it should work in old school diesels...

Simple Centrifuge ...putting a centrifuge in every garage!

There's heaps about this on the web


JC,

It is filtered in the engine by the oil filter. Fuel is filtered before it gets to your pump or injectors. Carbon is a lubricant not an abrasive. Dilute it 3 parts diesel to 1 part used engine oil. Its been done for years all round the world.
Would I use it in my Disco? Probably not.

I have seen British Field Marshall and Lanz Bulldog tractors run on a mixture of sump/gear oil and parts cleaning fluids. Looked like a steam train coming in the distance

To a much larger size than a diesel fuel filter filters to.

Sorry but that is complete rubbish.
e.g. see http://papers.sae.org/2000-01-1990/ and many other papers on soot induced wear

That doesn't mean it is a good idea (e.g lots of people fit K&N's, hiclones and fuel polarisers...). A few weeks ago I posted a recent paper by Cummins which states that lube oil [sump oil] should not be added to any diesels (including cummins diesels of course).

It is illegal in most 1st world countries these days AFAIK.

carbon is a lubricant....

when its specially shaped, into the form of graphite and kept dry.

Graphite lube, best thing for the ignition lock (not the switch) in your defender...

till some idiot sprays wd40 or similar in there.
