If this turns out to be true it will be an interesting test for emusified water...

TCEQ sorry for misspelling.
All diesel sold in 119 counties of east Texas will have to meet TxLED requirements. http://www.tceq.state.tx.us/assets/public/implementatio...s/DRAFT.TxLEDQnA.pdf

Notice that B100 is dinged for increasing NOX by 10%.

They have added some other blends since I last visited the site. http://www.tceq.state.tx.us/implementation/air/sip/clea...el.html#Formulations

Purinox is onlt 77% diesel, 20% water, and 3% additive. I wonder how much extra they will charge me for watering down my fuel?

It looks to me like lots of people will be forced to do your experiment for you this summer.

I sure hope I am misreading all this. I would prefer water/methanol injection in the air stream to running water through the fuel system.

Hello, I have been reading the thread and find it very interesting. I was thinking about doing a similar test. I would like to offer some information and assistance. First the info. Cavitation is a two stage process with liquid flow. The first stage is the formation of vapor bubbles in the liquid as the fluid moves through the system and the pressure is reduced below the fluids vapor pressure. The second stage is the collaspe of the vapor bubbles as the fluid passes the vena contracta (where the jet of flowing fluid is the smallest. At the vc, the fluids velocity is the highest and the pressure is the lowest.)and the pressure recovers and increases above the vapor pressure. The collasping bubbles are very destructive especially when they contact metal parts. The bubble collasping may produce high noise levels (ultrasounds between 20khz and 100 khz). Another note: Cavitation damage problems are more likely to occur with water flow as water has a well defined vapor pressure and the vapor bubble collapse is instantaneous. Hydrocarbons fluids have a less precise vapor pressure and are often a compound with several vapor pressures. The cavitation damage with hydrocarbon fluids is usually less severe than water as the bubble collaspe is not as sudden and can be cushioned by other vapors. Now with that said, it is sometimes possible to detect the bubbles breaking(cavitation) with an ultrasound probe ($$$). I happen to have one and would be willing to offer my services. Unfortunately I am in northern Minnesota. I like the idea of performing the test without the engine as it would eliminate competing ultrasounds. One suggestion would be to get UT baselines using diesel, new vo,
dry wvo, wvo with known water percentage. Let me know if I can help. Have An Excellent Day!

Maybe I am looking at a different website or page but I don't see how you could come to that conclusion?!

Purinox is an approved fuel under this regulation but so aparrently are many others. Most of the additives are just added so #2 diesel can still be used. And unless I read it incorrect using #1 diesel or Carb certified dieasel will also suffice.

I seriously doubt that many diesel owners will choose to use Purinox.

When I looked at it in the past, Purinox was the only one listed on the approved chart. Friday morning I was just rushing to post the links while at work. I am glad to hear there are better alternatives. I sure wish Chris would get a Dmax kit out so I can avoid the whole issue. I am currently running B99 but houston biodiesel is moving to a different part of town. Will probably be splash mixing down to B25 at the local station before making another trip over to fillup on B99 again.

TNX,

We should have a Duramax kit on the 'site within a week or two.

Vegburner.... Can get that link to open.

Just tried it and it works for me?

"Posted 17 May 2006 12:41 AM
Ran into this ( www.testing-expo.com/europe/05txeu_conf/pres/macdonald.pdf ) study the other day had a quick scan and noticed some stuff about cavitation of gas in fuel injectors thought it may be of interest, not sure how relevent."

Not much more to say about emulsified fuels. I've posted information about how surface acting agents (surfactants)work and the correct terms to be applied. Even posted a few possible
ready to be bought surfactants. I also have a document with Bio-D & water emulsions....the surfactant was glycerin(ol?).

What I do find fasinating is Vegburners link.
Sonically induced photoluminence....Wild

BTW Fatty, Gunnerman was suggesting the use of platinum (to act as a catalyst) in the intake manifold. So the A21 would be partially cracked as it entered. Without the retrofited manifold gassers had very poor proformance or would not run at all on A21.

There are better ways to incorporate water in the combustion process, than mixing it in the actual fuel. Unless you looking to bring down viscosity.

Well,
Ive been hunting for cheap parts....
Injectors & injection pump to start the little experiment mentioned above...so far i missed by a few dollars.
I guess i will just have to pony up and pay.

I agree with Dana that parts should be new and benchmarked. If we priced what everything would cost and maybe everyone pitch in some $$ in exchange for the info gathered I would be interested.

This little experiment will have to wait a bit longer...I am going back to Iowa (The capital of wildly outrageous taxes and weather that has to be close to the worst on the planet...oh yeah and the home of a new dreamed up fee a "clean water program fee"...which has a 7%sales tax tacked on for good measure...It seems we need to clean the rain water now before it reaches the Mississippi,I wonder if this will benefit the people in New Orleans?
Do we get a rebate if there is a drought? )
Near the end of June i will return.
I figure that i can get a remanufactured Ford pump for somewhere around $375
the lines for maybe $50
and the 8 injectors for somewhere between $100-200
so in round numbers $600 bux should put it all together
If 10 people want to play thats only $60 dollars a piece ....if not thats ok...I am still GOING TO DO THE EXPERIMENT...Its just if i pay all the money....then there wont be alot of anyone elses ideas experimented with.

As of this moment i just want to run cold blend with a little suspended water and tear the pump down 1/2 way through to see if there is any damage or unusual wear.

Perhaps i will be able to buy some of these things on my little trip.
