General Discussion / Re: Piping exhaust outside, safe options needed
« on: November 25, 2007, 05:21:51 PM »
Will the bender in a automotive exhaust shop do it?

Most any electrical contractor will have the ability to make the bends for you.  Just a matter of contacting one willing to do it at a reasonable price.

Most have pipe benders for bending 3/4 inch up to and sometimes more than 6 inch pipe.  Standard pipe, not heavy weight pipe.

Listeroid Engines / Re: Offset Idler bolt install report

It sounds like as with many things gear making is quite an art. It seems like the gears have "seated in" and are running silent now. Perhaps I will remove the cover and inspect them next week.
Thanks for the informative post Mike.

Tom,
Mike's post was extremely informative and accurate.  You observation that the noise has decreased substantially, seems to me to be a strong indication that they have in fact "worn in".  Hobbing and shaping machines make cuts parallel to the gear shaft centerline whereas rotational wear reshapes the gear teeth perpendicular to the gear shaft.  Minor machining marks and irregularities are gradually worn away, assuming the conflict is not gross or totally out of spec.
I would think an inspection would be in order, but since the noise had dissipated, I would not lose sleep over it.  Certainly keep an eye on it for safety sake, but it sounds like it's all good to go for now.

Really interesting thread here!
My question though, if I run a diesel that was designed for 3600RPM at 1800RPM and load it properly will it be likely to wet stack or will other more important concerns exist?
Seems to me that the load will prevent wet stacking, but valve timing, injection timing, etc might create problems that are way over my head.
Would only half rated RPM also indicate only half fuel consumption or is this question too vague or unanswerable because of not having specific engine information?

I'm certain that you can ask for a refund of whatever financial assistance you have supplied here on your way out...

Guess I didn't have my "nice" hat on that day.  What I should have said is "If it were me and I were as upset as you seem to be, I would have asked for a refund and left the site".  Of course, I have not contributed financially and assume most of us have not.

Thanks for the site, Admin, I appreciate it.

Engines / Re: Acetone in Diesel Fuel???
« on: July 30, 2007, 04:09:45 PM »
Acetone added at 1 OZ (volume measure) per 5 gallons. Wallyworld had a nice little graduated beaker for less than $2.00 .
As to carbon - while I suppose it would have to (mostly anyway) blow out as carbon solids, the formation of new carbon deposits, if La Pointe's hypothesis is correct, would be minimized by the oxidation of carbon to CO2.
I noticed an immediate reduction in soot around the machine, which had been raining down in the area. This may be a false impression, very subjective. But it suggests that the CO2 path is the dominant one.

Phaedrus,

Any further observations to adding acetone to diesel fuel?

Have/are you testing the Ford diesel by adding acetone?

Inquiring minds want to know.....

I've read thru the posts here, but I'm not sure I've seen a specific answer to this question.
Rather than have a separate heated  WVO tank, is it possible to just filter it and blend it with low sulfur on-road diesel to run in a VW diesel?  What ratio is possible with no issues as far as thickening in the lines? I can get 5 to 10 gallons of WVO per month, and would rather just add a bit at a time
to the regular fuel tank......if possible.
thanks
dk 

dk,

Field tests done by U. of Idaho using most major diesel engine brands showed definite coking problems at vegetable oil usage of 20% and above.  Lower veg oil percentages seemed not to cause problems.  I have read many private persons recommending up to 35% veg oil as not problem causing, but I seriously doubt most any claims over 20% (unheated) being safe.

Adequate filtering and de-watering should be considered an important requirement, in my opinion (as in many other's opinions).

Waste Vegetable Oil / Re: Blending WVO & Diesel
« on: July 03, 2007, 03:51:56 PM »
It all has to be properly disposed of and usualy sits in a waste fuel tank some place. We used to filter and blend some of it our own use, but stale gas is still bad gas. Av Kerosene ended up filtered and in the trucks.
Trouble with waste fuels they tend to be shipped in drums that weren't clean, poured into holdings tanks that aren't clean and even if you filter it what you get is mystery fuel containing oil, solvents in some cases and possibly still some water.
Doug 

Yes Doug,

You make a very good point.  The one point I disagree with is the line  "stale gas is still bad gas".  I contend that if you are confident the stale gas does not contain other substances/chemicals/contaminents, I believe it would be good for usage as a fuel oil blending agent (not as a fuel for a gasoline engine).

The water will settle out of stale gas unless a contaminent that absorbs water is present, and in my opinion, water that is fully suspended is not necessarily a bad thing.

Fred,

The link I was actually thinking of was the thread here by "SODBUST".  I left a "bump" message there in the Alternative fuels - Straight Vegetable Oil.

Someone in the infopop forums seems to have found a substantial supply of "stale RUG", and someone else found quite a bit from boat-yards.

Danial, welcome.
I too, would like more information on your svo/gas mix, and your centrifuge project.  Thanx for the link to your website, I found it very interesting!
Cheers, Fred

Fred,

This post is essentially a "bump" to bring it back to the top of the list.  Sorry all but I think some of this information should (or could) answer
Fred's question in the thread where he asked about blending veggie, dino and acetone.

I guess I really mean the first half dozen posts, not the "war" between Fattywagon and Dana Linscott that follow.

Everything else / Re: belt tensioner a good way?
« on: July 01, 2007, 05:41:34 PM »
would like my engine to operate at 3 different speeds. Is a belt tensioner  the best way to go?   Most here run one speed and
use  some sort of base to adjust the genhead.  Choices are to have an adjustable base, idler/tensioner or a dual idler/tensioner,
a squeese on the top and bottom of the belt.      the engine is mitsubishi L2E - 900-3600 RPM
Thanks,  David

David,

Is your intention to run multiple belts to multiple devices from multiple pulleys and select the device by engaging the appropriate idler/tensioner?

Thanks Vic,
Will  some research on RUG and see what comes up.
In the meantime, any information is, as always, greatly appreciated.
Cheers, Fred

Fred,

I haven't found the link I was looking for but did find another that you might be interested in.

http://biodiesel.infopop.cc/eve/forums/a/tpc/f/9751014871/m/5101050991

Probably no difference (in thinning ability) between fresh RUG and "stale" RUG.

Waste Vegetable Oil / Re: Blending WVO & Diesel
« on: July 01, 2007, 02:20:57 AM »
Just picked up a 1986 BMW 524TD and want to experiment with blended WVO and diesel (probably with a little acetone in it just for fun ;D ) With daily highs around 86 and lows around 76 I think I'll be able to get by with a single tank just by heating the fuel injector lines; hopefully 75/25 mix.
I'd like to maybe do something similar with the listeroid.  Any thoughts would be appreciated. (car, roid or both).
Cheers Fred

Fred,

Everything I have read points to a WVO temperature of around 170F.  I assume you are suggesting a 75%WVO/25%dino?  University of Idaho testing has concluded that vegetable oil blended at rates above 20% causes major coking problems.  I have read of very good results using small amounts of Regular Unleaded Gas (RUG) as a blending agent.  I assume that even "stale" RUG would accomplish the same thing.  I will try to dig up a link  for you.

Phaedrus,

Your observations are very interesting.  Mostly the same as I have heard/read elsewhere.

Do your plans include testing acetone in your truck fuel?
