2006 on Homebrew?

[SteveAnsley]

What's the consensus of running homebrew in a 2006?



I have a '98 12 valve that I've been running homebrew in for just over a year.

Obviously, not a problem at all in a 12 valve.



My brother has a friend driving an '06 Dodge that wants to run homemade bio-diesel.



He's planning on coming over to check out my setup and just want to be more up to speed on any concerns w/ a common rail setup.

I brew in an Appleseed setup, water-wash, followed by a dynamic drying process - every batch has passed the 27/3 test. I think my brewing process is complete, but I'd hate to lead someone else astray - I realize every motor is a bit unique.



Any concerns w/ a 2006?

I am also interested in this subject, my 99 is getting well worn with all the dirt roads it sees and am thinking of an up grade to a 05 or 06 this year. I have ben running the 99 on home brew B100 for the better part of 2 years now and cant see going back to dino.

heres some info

The Methanol Test from JTF or the 27/3 Test



This test found on JTF suggests that dissolving finished biodiesel into methanol is a test for quality. As with much information on JTF, this one has good and bad information. JTF states "The biodiesel should be fully soluble in the methanol, forming a clear bright phase. If not, there is pollution in the biodiesel. Each ml of undissolved material corresponds to 4% by volume. Is there any undissolved material at the bottom of the measuring glass? If there is, your reaction is not complete and this is causing you trouble with the water test. " Testing has found that the clarity of the methanol is effected by enough different things to make clarity of the methanol meaninless. Also attempts at correlating the volume of undissolved material to conversion have not been successful.





There has been a good bit of validation testing performed on this test by the people posting on the infopop forum. They found that if a portion of the biodiesel does not dissolve in the methanol then there are quality problems. It is futher discussed on infopop after being introduced to the board by Tilly.





Neither Triglycerides or Diglycerides are soluable in dry methanol, but Monoglycerides and Biodiesel will dissolve in dry biodiesel. If significant Triglycerides or Diglycerides present will fall to the bottom of the test.





To perform the test add 1 part biodiesel to 9 parts methanol, by volume. On infopop many use 3 mL of biodiesel and 27 mL of methanol and call the test either the Jan Warnqvist test or the 27/3 test.





Triglycerides and Diglycerides will form a precipitant on the bottom. Only a liquid precipitant that collects together to form a bead or bubble that rolls arond on the bottom of the test is significant. If you have a liquid precipitant then your biodiesel is under converted.





Your methanol should be dry and you perform this test at room temperature, as most of the validation testing on this procedure has been performed under those conditions.

What is a dynamic drying process and a 27/3 batch test?

Dynamic as opposed to passive.

Some people (not many) will just let the water settle after the wash - takes a lot of time I'd imagine.

I have a drum set-up that has a heating element in it and use another clear water pump to circulate the diesel through a couple shower heads that allows the water to broken up and dispate into the air.

Here's a link from where I copied the setup:

The bottom (ends up being the top) - I ended up cutting most of mine out, just leaving a 3" wide strip from edge to edge for mounting the shower heads. (allows for better air flow).



I agree about not heeding too much info from the JTF website.

I get most of my info from the Biodiesel & SVO forum:

Boy, if you think we get out of hand on this board... just bring up a JTF concept over there... ...
