Hello Jonathan et al The main problem with SVO is the high boiling point. This includes both the FFA and the SVO molecule itself. The points of turning the SVO into biodiesel are the following: 1) The final boiling point of the fuel will not exceed 370oC, which is proper for modern small and middle-size diesel engines. 2) The viscosity will drop til approx. max 5cSt, which is acceptable to modern small and middle-size diesel engines. 3) Using the proper recipe when performing the process, the FFA will be reduced or saponified. This will make the fuel less corrosive, assuming that the alkaline metal content of the biodiesel is taken care of . 4) The chemically bounded glycerine in SVO will partially be released from the SVO in hot environment. The glycerine is hard to combust, since it rather forms deposits than CO2 and water.

Lately, I have been doing a lot of reading on the different systems for using SVO. Elsbett seems to have one of the best single tank systems for this. I have made good biodiesel, but with rising costs of methanol, I was looking at alternatives. I have read about fuel mixing and admit have tried the DSE just to see what all the hype was about. I agree that there is nothing really special about their ingredient and most of the thinning and diluting is done with the kerosene and gasoline. It seemed to work fine in my 300SD, but the more I read, the more I learned of the negative aspects(incomplete combustion, coking, ring sticking, etc.). I understand that I should only try things like this for short term experiments, which I have. Is it the FFA in the vegetable oil that causes all of these problems? Is that why biodiesel will not cause these problems, because part of the process removes FFA? I also read about the experiment that concluded that in order to achieve the same atomization as petrol diesel, the rapeseed oil was heated to 150 C. This is twice as hot as most of the 2 tank SVO systems that are on the market now. Would this mean that you would still have incomplete combustion if 150 C cannot be reached? If Rudolf Diesel invented his engine to run on a variety of fuels, including vegetable oil, how come the engines of today require more modification or fuel modification to run veg oil? My last question is concerning the Elsbett single tank SVO system. If you can just pour the veg oil in and go, is there a heater on the main tank for cold weather? I am not even sure that SVO will work for me since I drive 12 miles one way to work. My car gets up to operation temp. half way there. Thanks all. Jonathan Schearer.
