Hello Keith, We ran the lister type diesel engine directly with Jatropha oil, which was just sedimented. The only adjustment of the engine was a second fuel filter.
A UN-project took this over and they were disseminating the Lister type diesel engines with plant oil. But right now they don't mention any more the aspect of runningf the engine with Jatropha fuel. see: http://www.ptfm.net We also had a study done by a German diesel engine producer. He concluded that the Jatropha oil can be used as fuel without problems. He also used the Jatropha oil as lubricant and said it is ok. Our idea was, to use the oil first as lubricant, and then burn it as fuel in the engine. ----- Here in Germany modern direct injection diesel engines are converted to run on SVO. There is also a modification kit available for precombustion chamber engines, which you can install by yourself. In a workshop in Denmark even an musician was able to do it, so it should not be too difficult: They change the injectotor to a pintle injector and change the incandescent plug (?) to one which glows much longer, if not almost permanently. Then the fuel pipe from the reservoir is replaced by a larger one, and a second fuel filter is added. This filter is heated with en electric heat band. Also a heat exchanger is installed, which gives the heat of the cooling water to the oil. The are also some switches and relais to regulate it. The whole systen costs about 800 Euro/US$, that depends on the car. http://www.elsbett.com At the 7. of July there is a meeting of SVO drivers/users in Germany. I will go there. Perhaps I know a bit more about the subject afterwards.
