Re: [Biofuel] SVO and titration
Candle filters 100um, 20um, 1um, no vacuum, no heating. I let stuff settle for a while and avoid surface and bottom. Dont know, possibly nothing. 1um sounds better to me than 10um and does not cost any more work or money. On 6/28/2011, Thomas Irwin wrote: How do you filter WVO to 1 um?

Re: [Biofuel] SVO and titration
Hello all, i am at that point of adding a second tank to my vw cabrio, which i converted to diesel. I am sure you all have talked about this before so pardon me or direct me to the archives. I am wondering which valving system have people used with a second waste oil tank as well as the screen to remove most impurities. thanks, ray Date: Wed, 1 Jun 2011 07:47:25 + To: sustainablelorgbiofuel@sustainablelists.org From: [EMAIL PROTECTED] Subject: Re: [Biofuel] SVO and titration A question for SVO users - do you actually bother to titrate WVO to check the quality?

[Biofuel] SVO and titration
A question for SVO users - do you actually bother to titrate WVO to check the quality? Titration for SVO http://journeytoforever.org/biodiesel_svo.html#titsvo Some people just chuck it in and go, others filter it and centrifuge it, which has no effect on the FFA content: Acid contamination can and will damage your engine. Filtering has no effect -- zero effect -- on the acid content of the oil. Centrifuging it also has zero effect on the acid content. - The German PPO fuel standard (see above), the only existing quality standard for SVO, sets a maximum acid value of 2.0 mg KOH/g. - Elsbett Technologie says oil that's too acidic can affect the lube oil. - The Fuel Injection Equipment Manufacturers (Delphi, Stanadyne, Denso, Bosch) say it corrodes fuel injection equipment and leaves sediments on parts. - Engine damage of a car using the BioCar SVO system was traced to a supply of soy oil which was not the usual food-grade oil and had a high acid content. An examination of the defective sections found substantial surface erosion of the hardened steel high pressure parts, which are not acid-proof. - Straight vegetable oil as diesel fuel Fuel quality http://journeytoforever.org/biodiesel_svo.html#gnl In Japan, with an Elsbett system in a Toyota TownAce, we only used oil titrating at less than 2 as SVO. If it was more than that we used it for biodiesel (which is much better fuel anyway, IMHO). Also, any comments from long-term users of two-tank systems - are they really inferior to Elsbett-type single-tank systems? Has anyone had difficulty getting a response from Elsbett? Thanks!
