Bio-Desiel?????!!!

[LightmanE300]

Cummins' statement is that they neither approve nor disapprove of bio use. They RECOMMEND up to 5%, but that doesn't mean they are saying any damage will occur with higher blends - if you read their lenghty publication on bio, the bottom line is they experienced no damage at 5% and haven't tested enough at higher blends to be conclusive at the time of publication.



I've burned over 4200 gals of biodiesel since 2001 - it's good stuff. In my CTD I've run up to about b40 with zero issues.



Typically b100 is running between $3-4/gal. ACERF you are one lucky guy to be able to buy b100 that cheaply... If I were you I'd fill up halfway with dino and then top all the way off with b100. It would be running silky smooth, that's for sure

Frak if you stick to purchasing ASTM spec commercially produced biodiesel you won't have an issue.





Bio has higher cetane and MUCH higher lubricity than dino diesel. Even at 2%, the lubricity is doubled compared to dino.

I mentioned in another thread (possibly on another site) that I got a packet of info from a soydiesel co-op. One of the papers in it was a letter from the pres. of Stanadyne singing the praises of biodiesel. I can't find that letter anymore, if I do I'll post it here. Another paper was a story about a mine in Kansas that ran all their underground equipment on B100. The workers love it, less smoke/smell in the tunnels.



I currently run 5%, but that's gonna go up next time the delivery guy comes out. It is still more, how much depends on what % I have him mix it.



I'll go see if I can find that packet of info.

frank, there's a phillips 66 in boise that sells it. it's only b20, and spendy though. and it's STILL a long drive. wagstaff is saying he's going to start producing it for his dad's business though. and that he'll have extra.



on another note, i really don't understand this propaganda of the stuff being more expensive. you can make it YOURSELF, in YOUR OWN GARAGE, for 50 cents a gallon. i don't think i've ever heard of anybody doing that with a petroleum based fuel. iow, there is NO WAY that it cost more to manufacture. period. yes, i understand that facilities need to be built, etc. , but it isn't that difficult of a process. and it's sooooo much better for our engines. anyway, enough of a rant.

Hi guys

I had tied the bio diesel and it was beter in the truck then old stuff. I did not see any more in the fuel mileage But i did see in power increase when you take off the line or when you pass someone :-laf and its but about . 20 cents cheaper then diesel.

well, if you are seeing more power, and less $$$ than #2 diesel, i'd be buying it exclusively

 

[HEMI®Dart]

I want to try Biodiesel. The problem is I can't get it around here yet. If I drive 40 miles, I can get it in jugs only.

 

[mudgeek]

I've run several tanks of both b-100 and b-20 with good results. Had a minor b-100 geling problem when the temp. was about 28*. I pay $2. 89 for b-100 and &2. 69 for b-20 in Colorado. petro diesel is about $2. 39. Bio-diesel is a renewable,US produced, resource. I think thats cool :-laf

I wrote to DC and asked about the use of Bio in my 2003. The answer was that they do not recommand the use of Bio fuels in my vehicle at this time!

 

[JBlock]

I found two but I couldn't find the one that I was thinking about. Click on one of these two... (1 ,2 )

Try search on the NWBombers.com site too, several guys making their own diesel over fromWaste Veggie Oils. I. e KFC, Burg King, McDonalds and others.

DC and Cummins both say B5 is fine. The reason they say that is about 2 years ago the EMA (engine manufactures association) said "Biodiesel blends up to a maximum of B5 should not cause engine or fuel system problems," Note they didn't say higher levels are bad, just that B5 is good. They didn't feel they had enought data to be comfortable with higher ratios. Manufactured repeat this recomendation.



DC is putting B5 as factory fill in the Jeep Liberty diesel.



Commercial bio diesel is ASTM spec and EPA approved.



If the fuel is determined to be the cause of a problem, the fuel supplier is the responsible party, for petro, bio or home brew. they all are treated the same.

Does anyone know the particulars about the new tax breaks coming out for using bio-diesel?

 

[Jefff929]

Remember when you do use Bio-D put the Dino in first and then the Bio, it will mix better Used B5, B20, and B100 never exclusively, always with regular Diesel in the tank. The most I’ve ever run was ~ B50. Never had any issues. Keep an eye on the fuel pressure or just plan to change out the FF if you have never used it before. The higher solvent content will clean all the crud outa the tank and your lines. Gelling might be an issue if your running more than B50 in the colder climates.

When you run bio, do you notice any differences; power, mileage, noise, smoke etc?



For the benefit of others reading this, I would say bio has a cleaning effect rather than "solvent content". Commercial bio has no solvent in it, but it does loosen up crud left by petro diesel.

 

[Diesel Nut]

What is the difference between B5, B20, B100? Advantages? How do you use it?

It amounts to $0. 01 / % of virgin bio in the blend. The $ go to retailers or distributors, so the price you pay will depend on how much they pass on to you

I have an Edge EZ, with a FASS LP, and can normally get her to lightly smoke when I get on it. Running Bio smoke is visibly reduced! Because the pumps are miles apart and I don't fill at the same time, I put the denser B100 on top to mix it in. It mixes well, no starting or other issues, with the exception of I can’t seem to get it to smoke. The motor seems quieter to me, I'm not a good judge, I don't hear so good.



B5 = 5% Bio & 95% Diesel blend

B20 = 20% Bio & 80% Diesel blend

B100 is the straight stuff 100% Bio-Diesel.

 

[ACerf]

Speaking with someone from DC, they do not recommand using the Bio-Fuel in my 2003, at any grade level. I sure this is their way of getting around any warranty issue that my arise during this period.

 

[Silver Bullet Ram]

And George Bush was seen with a Dodge Ram in Virginia the other day running on Biodiesel. How can DCX say not run it.

[FATCAT]

For those who are running Bio, what would be your advice when switching over?



How many fuel filters do you need to replace and how often until the "crud" is out of the tank? Every 500, 1000, etc... miles?



Since I have an old 97 with a p-pump, I'm sure there would not be a problem running it, I just would want to know what to look out for when switching over.

<ABS>Abstract:

This study explores the diesel injection and combustion processes in an effort to better understand the differences in NO<SUB>x</SUB><SUB></SUB> emissions between biodiesel, Fischer-Tropsch (FT) diesel, and their blends with a conventional diesel fuel. Emissions studies were performed with each fuel at a variety of static fuel injection timing conditions in a single-cylinder DI diesel engine with a mechanically controlled, in-line, pump-line-nozzle fuel injection system. The dynamic start of injection (SOI) timing correlated well with bulk modulus measurements made on the fuel blends. The high bulk modulus of soy-derived biodiesel blends produced an advance in SOI timing compared to conventional diesel fuel of up to 1. 1 crank angle degrees, and the lower bulk modulus of the FT diesel produced a delay in SOI timing of up to 2. 4 crank angle degrees. Compared to conventional diesel fuel at high load, biodiesel fuel blends produced increases in NO<SUB>x</SUB><SUB></SUB> emissions of 6-9% while FT fuels caused NO<SUB>x</SUB><SUB></SUB> emissions to decrease 21-22%. Shifts in fuel injection timing, caused by bulk modulus differences, were largely responsible for the NO<SUB>x</SUB><SUB></SUB> increases, but pure FT diesel produced lower NO<SUB>x</SUB><SUB></SUB> emissions than expected on the basis of SOI alone. Further analysis showed that no trends were seen between NO<SUB>x</SUB><SUB></SUB> and either ignition delay or maximum cylinder temperature, and only weak, or fuel-specific, relationships were seen between NO<SUB>x</SUB><SUB></SUB> and maximum heat release rate and the timing of maximum heat release rate. The timing of the maximum cylinder temperature, however, did produce a relationship with NO<SUB>x</SUB><SUB></SUB> emissions that was not dependent on fuel type.

That's an abstract from a study I found while browsing the ACS archives. Evidently according to this, the NOx emissions increase due to an increase in advance timing from the biodiesel, if I'm reading that correctly. This is likely the reason DCX doesn't recommend higher blends of biodiesel, simply because it could put them out of emissions compliance, at least that's my guess.
