Re: [Biofuel] BD disinfo from SVO kit vendors
Hi all, I find it difficult to embrace any SVO technology. That is for many reasons, but the most outstanding is the high boiling point of SVO:s. Canola vaporizes completely at no less than 650-700oC, which is far too high for modern diesel engines which have a limit of acceptance at approx 350oC. This means that the SVO cannot combust completely in a diesel engine. This leads to deposits in the engine, some of them lethal to the engine, and lubricating oil contamination. This is a fact that no SVO kit can cure. I was into a SVO project during the 90:s and we found one additive that could keep the deposits at a certain level. But the composition of the additive was such, that the handling of the fuel became environmentally undesirable, also from the human health point of view. If somebody has an attractive technical/chemical solution for this I would be very interested to hear about it.

Re: [Biofuel] BD disinfo from SVO kit vendors
Hi Jan I agree with you. The ACREVO study found that veg-oil must be heated to 150 deg C (302 deg F) to achieve the same viscosity and fuel performance as petro-diesel: "Atomisation tests showed that at 150 deg C the performance of the rapeseed oil is comparable with that of the diesel oil." http://www.nf-2000.org/secure/Fair/F484.htm That's double the temperature the two-tank SVO systems use. At only 70-80 deg C. veg-oil is still much more viscous than petro-diesel - six times more viscous in the case of rapeseed oil (canola). And I don't believe it combusts properly. Anyway, Elsbett optimises the injector nozzle spray pattern for SVO, and it certainly helps. The Elsbett system has good long-term performance. I think the same applies to the other German single-tank SVO systems (more expensive). We got an Elsbett system mainly to solve the problem of using biodiesel in winter. Our WVO biodiesel is okay to about -5 deg C, but it gets to -12 C or lower here. We were using an additive, but with the same reservations as yours, it's toxic stuff. With the Elsbett system we've used biodiesel through two winters without additives and without any problems. For two years we used SVO during the summer and biodiesel in winter - the SVO was no use at below -5 deg C, it gelled in the tank, and the Elsbett system doesn't come with tank heating. But we stopped using SVO this year. Even with the Elsbett system, though it works, I don't think SVO is good fuel. We only use biodiesel now, all year round, and the Elsbett kit fills its original purpose of solving the winter problem with biodiesel. I'm glad we've dumped SVO. It doesn't compare with biodiesel, IMHO. Such statements are likely to cause furious protests from the SVO crowd, but facts are facts, and you pinned them down: coking, and lubrication oil contamination. Another point: when we have biodiesel seminars here or give demos, part of it is to start up the TownAce and everyone goes to the rear to experience for themselves how non-irritating biodiesel exhaust fumes are. I usually end up asking if I can get them some chairs and a cup of tea - they stand there behind the car chatting away about this and that, completely forgetting that they're wreathed in exhaust fumes. LOL! You sure wouldn't do that if it was burning petro-diesel, and not with SVO either, SVO fumes stink. Maybe not as bad as petro-diesel, but people never just stand there chatting when it's running SVO like they do with biodiesel. Trust your nose! Actually this study found SVO emissions are worse than petro-diesel in some ways: http://130.132.94.20/images/StudResearchInfo/ME_ELLIS_GEIST_WIZNIA.PDF Here's the full report: http://www.yale.edu/yedt/biofuel.pdf Still, to each his own. I think we'll probably only have really good solutions for SVO fuel when there's enough demand to persuade the car-makers to design true multi-fuel engines, and that will only happen (maybe) once a large number of people are using the existing SVO systems, for all their shortcomings. I just wish they'd stop all the BS about biodiesel, it doesn't help. Regards Keith Hi all, I find it difficult to embrace any SVO technology.

Re: [Biofuel] BD disinfo from SVO kit vendors
Jan, SVO having a high boiling point doesn't mean it can't be used instead of dinodiesel in a diesel car, because, ... normal Diesel fuel is also completely evaporated before combustion. What you need is a fine mist, not evaporated fuel in a diesel motor. Dino diesel has a boiling point, rather a boiling-range, between 340 and 400°C, so even dino juice will not be much vaporized at the time of ignition. But it's possible that the higher the viscosity, boiling point, and vapor pressure is, the more difficult it is for your dieselcar's hardware to make the ultimate mist who gives the ideal burning of all fuel components. Thats why SVO conversion kits alway's have a fuel heather device in it to lower the viscosity so the pump - injector combo can produce a optimal ( or as close as possible ) mist. At 95°C sunflower oil has around the same viscosity then DD at 15°C. DOE and other governmental organizations still claim that SVO will shorten the live span of your motor and more cooking and reduced motoroil live span will appear. Mixing with dinojuice or an additive can also help but is not the best or preferred option if you want to go fossil free. What additive did you use or tested?
