[Hidden-tech] Biodiesel

Frank,
 
Thanks for your questions! I'll reply to the HT list, as well, in case
others may have the same questions.
 
1 - Biodiesel is vegetable oil which has been chemically reacted with
methanol and lye (potassium hydroxide or sodium hydroxide)to replace glycol
chains with ester chains.  Chemically, biodiesel is the same as diesel, with
much lower carbon and ZERO sulfur emissions.  "Grease cars" run on waste
vegetable oil (WVO), which contain glycol chains PLUS fatty free acids
created by the heating of the oil.  WVO also has a much higher gel point and
viscosity, which requires a more extensive pre-heating/circulation system -
hence the "grease car kit".
 
The soy-based Yellow brand biodiesel I use is fully washed, as well, which
removes excess lye, methanol and chemical soaps leftover from the reaction.
Many biodiesel manufacturers won't perform this step because it adds
manufacturing costs, and most consumers won't ask about it - but it can make
a significant difference in engine/fuel system wear.
 
2 - Biodiesel has a higher gel point (35-40F) than regular diesel (10-15F).
In the winter, you can blend B100 (100% biodiesel) with dino-diesel to lower
the gel point.
 
3 - I appear to be getting roughly the same mileage with the same
acceleration/performance.  My engine has almost 250,000 miles on it,
however, so a little computer tweaking of my engine probably wouldn't hurt
at this point.  :)
 
If you're looking to pick up a used diesel vehicle, you'll probably want to
find one manufactured after 1995 - biodiesel is quite a  solvent and will
literally EAT rubber hoses/seals/gaskets in the fuel system.  The vast
majority of diesel vehicles manufactured after 1995 have synthetic rubber in
their fuel systems, so it won't be a problem.
 
Best,
Cody

Cody -

Thanks for the info.  I do have some questions for you.


1.	The video says you made no modifications to your engine.  There is a
local company here in Western Massachusetts that sells a modification for
biodiesel (Greasecar <http://www.greasecar.com/> ).  The question is why
does your car run without modification?  Is that not a necessary component
or are there different kinds of biodiesel?  


2.	How does it run in the winter?  Diesel is notorious for not starting
up in the cold.  As you're a Northeasterner, you would know!  Have you
experienced any other performance issues?


3.	Do you get the same mileage (in your case 45 mpg) with biodiesel, or
is the mileage actually enhanced or decreased using biodiesel? 

I'm in the market for a new (used, actually) car and I would consider a
biodiesel if I could be assured that I could get the fuel relatively easily
and that I wouldn't experience any performance issues (start-up, stalling,
etc.).

Thanks for the information!

Hey everybody-
 
For those of you who aren't aware, I've been running my 1999 VW Beetle on
Yellow brand biodiesel (made in Williamsburg, MA) for some time now.
Albany's WNYT just featured Stockbridge Gas (where I buy it), Yellow, my car
and me in a piece that aired Tuesday night.  They also did a follow-up piece
this evening about the Hudson Valley Biodiesel Co-Op, of which I am a
member.  You can see both videos at www.wnyt.com.
 
If anyone has any questions about biodiesel, I'd be happy to answer them.
 
Best,
Cody
