Mr. Erickson, I guess that the simplest answer to your question would be that the US DOT recognizes biodiesel as an approved on-the-road fuel as long as it...
what you have heard is more than rumors... unconverted oil in under-reacted biodiesel *is* bad for diesel engines. Now, if your engine is an older InDirect...
Alex, Can you point me to any studies on the effect of burning biodiesel with unconverted oil? Where did you get the information that it is bad? I have a '91...
Matt (call me Dave), I didn't express the question very well. I only brought up the ASTM standard because it specifies the amount of glycerin that can be in...
OK gang, Everybody has their own opinion. And in a way - everybody is right.... But the "true" skinny is simpler than you all think... Point One: Yes you can...
... Only in winter; adding a little unleaded gas then will dramatically reduce the viscosity - I need to complete more testing, but early tests show that...
FIELDS OF FUEL is a feature length theatrical documentary about one man's search for an alternative to America's dependence on foreign oil. America is engulfed...
Dave, While I appreciate your efforts to clear up some misconceptions, I think that you've added fuel to the fire so to speak. Biodiesel is not mystical it's...
Dave, I am sorry I might have miss understood you original question. As to why the ASTM limits the amount of glycerol has to do with the presence of unreacted...
Mark, That was a very informative and well written post. Thank you! Eric ... think ... mystical ... first try ... for a good ... out there, ... supported by ...
Someone made a good point about the fact that USDOT recognizes biodiesel as a road fuel but not SVO, I think that has a lot to do with it. In addition, my...
Matt, Thanks. My understanding is slightly different, and perhaps you can correct it. I don't know if you read Mark Tapsak's excellent description of biodiesel...
... How do you know this? Free glycerin perhaps, but how about monos and dis? I don't understand why, if the SVO people don't report these problems. ... From:...
Dave, The ASTM standards were passed to cover all diesels on the road today, including older diesel and modern ones. That being said older and heavier diesels...
Matt, Thanks. Couple more questions: What is "coking"? If running SVO at normal operating temperature does not cause coking, why does running BD with unreacted...
Because SVO is primarily made up of triglycerides...not monos/dis. SVO can have this problem as well if not properly heated to reduce it's viscosity. The NREL...
The obvious question here then is: whattheheck is "NREL"? ... -- Ray Kotke www.telephonecreations.com [Non-text portions of this message have been removed]...
... The NREL is the National Renewable Energy Lab. There was a reference posted to them about five messages back. Someone explained things well a few messages...
Dave, Coking can best be described as unburned fuel that collects around the ring of a cylindar, if left in place it can cause the engine to cease, or at least...
I know that this is a little off topic but I hope that we can use it to show the non believers the need for biodiesel. I know for myself that I have been...
I have been using NAOH with success for a while, but recently switched to KOH for the lower environmental impact of my wast byproducts. I have made two batches...
Dave, This is anecdotal since I'm driving an '83 Mercedes diesel but there is a forum on www.Greasecar.com with a number of members driving VW tdi on recovered...
Matt, Even though the engines are aluminum the cylinders are steel as well as the values with chrome rings.. Some carbon and coke can be blown out by stepping...
... tdiforums talks about tdi's and s/wvo, but the two common factors are a) heating the fuel and b) changing the injectors. I never said TDI engines can't be...
Why would mono/diglyceride burn any differently than triglyceride? If the mono/diglyceride is distributed evenly through the biodiesel, and the biodiesel is at...
Ok... The ATSM Specification is a "bench mark" If the fuel meets the ATSM specifications it has the correct viscosity for "normal" operating temps (but how do...
