Just found this and am in no way promoting it. Just looked like something the group might like to check out.

Moderator might have to modify this as when the kickstarter campaign is over the link might fail.

YES

Ok guys

Now how about a source of repair parts for these engines. Anyone have any place where reasonably priced injectors and pump parts can be had.

My son in law acquired and gave to me a probably wore out APU off a semi that has this motor in it. The story goes the semi owner tossed the whole unit after he had the injectors and pump removed for repair. I have most of the injector and pump parts but am missing the injector lines. My guess is the parts new will be costly. Not knowing the engines internal condition but by judging from it's generally poor exterior shape I have concluded it probably is not worth the cost of new parts. Should pop the head off and see what it is like internally but just have not found the time.

I don't post much anymore but do try to read at least some of what is posted and this thread sure brings back memories. Went back and reread the first few posts and noticed that was when spencer was still posting. He sure was adamant with the fact as he seen it that WMO was a better fuel for waste oil fired heaters than diesel engines. And I see it about the same way. I sure won't argue like he did but he was right at least in slow speed lister like engines.

Not sure why some engines seem to tolerate WMO better but lister-oids sure don't. At least not the ones that are pushed to the limit. as I did with both of my single's.

I will say that  posters like rbodell do seem to have better luck but he was treating his oil to reduce acid as best as i can remember and after seeing a video of his engine running I will say it was running at a lower power out put level. I am thinking that is causing his better results.

Now back to my experience with burning wmo in my boiler that heats my farm shop. I go through about 1400 gallons a year and I can attest to the fact that there is sure a lot of ash in 1400 gallons. I remember the post that spencer put up showing the bucket fulls he pulled out of his boiler, it works the same for me on this side of the pond.

I will speculate that if a car type of diesel was run on a high % of wmo and was driven casually it might work. But take the same engine bolt a gen head to it and push it to 80 to 90 % full out put it might suffer the same fate as the single's I spoke of above.

But as others have argued they have had better results..................

Google the octane rating of propane. I believe it is high like 110. You will be able to run much higher than 9.5 to 1.
Like 12 to 1 plus or minus........................ more power...............................

That guy wouldn't stand a chance if that flywheel lets go.

Did you here it wind up. Really pushing his luck..................

seems to work for me at this posting time

Here is another design.

according to the date on the video I would think if it worked it would be in production.

Hello

For everyone reading this thread you all should go to you tube and search for home made centrifuge.

There are quite a few clips of differing builds.....

A few weeks ago I ran across one where some guy used a automatic transmissions torque converter as a bowl. I should have copied the link back here but was to pressed for time and thought I would be able to find it later but so far no luck.
Now a torque converter with part of one side removed  should be able to reach very high RPMs without the fear of centrifugal deconstruction so to say 
It is bowl shaped as quick as anything just need the drive and tank for it to set in.......

Be a lot easier than an aluminum bowl construction or the risk of iron brake drums.

+1 for what tom said

I destroyed a 10/1 listeroid on wmo but did get about 1500 hours + out of it.

Then switched to a 16/1 metro listeroid and it was well on the way to destruction before I just gave up on wmo in engines as fuel.

Now just use wmo in a waste oil burner.  just refilled the tank and am using 6 gallon a day to heat a 4000 sq ft shop.

You mentioned you built one. What did the store bought bowl cost? Do you have a Brand name possibly?

In the last few days I have come to the conclusion that a centrifuge might be needed as some of the WMO that I collect for my waste oil furnace can be real crap. Most guys I get it from do real well keeping the garbage out but I just picked up a 80 gallon batch that has some real fine debris in it that will plug up a diesel fuel filter way to fast.

I am the one who sold the Listeroid, and got the Witte.
Yes, it is BIG!!!  Actually TOO big for my needs.  I am in the process of acquiring another 6/1, and will be selling my Witte CD-12.
It's just too big for my arm (hand crank, not electric) and my loads. 
I bought the Witte hoping it would power my whole house air conditioning.
It will handle the constant load, but with 800 lbs of flywheels, the governor has a problem keeping up with the AC cycling on and off.  It takes almost two minutes for the engine to slow down enough for the governor to react to the 4000 watt AC load, and by then once the governor starts to add more fuel, the generator has slowed down to about 52 hz (should be 60 here) and the ST head voltage drops to under 190v (should be around 230).
Long story, it doesn't serve my needs well, and I will be looking for it to find a new home within the next year (as soon as I get my 6/1 here)

I Might be in the buying mood by the time you are ready to sell. Send me some info on  what you might want for the critter. Or am I to late already

Well join the party, I did the same as you are thinking of doing.

Have used a clean burn brand of boiler fueled with waste engine and hydraulic oil for 2 full seasons.

It was the smallest unit they sell at 200000 btu's.

That nasty crud that comes out of burning used oil does fill the burn chamber up. Thoughts of the famous poster spencer and his ash come to mind.
The company claims 750 hours between burn chamber clean outs. Well that might be a stretch, more like 400 hrs. With my experience.

You will have a problem finding a boiler in you size range, not to sure I ever saw one that small.

Price will be a problem too as mine cost $8000 before install.

Hate to quite here but soybean harvest started yesterday and my combine needs me.

Billswan  ps were you still going to use veg oil??  I Have zero experience with it................

Guys here is some news I stumbled onto.
I am not into solar but maybe someday.
