Ok, thanks again -yes, it's likely that Alex does use only new oil, I believe that is what is recommended for that system, and it would be affordable in Germany especially for him to do so, and they do have it in bulk, for sale, at their location (and SVO is for sale at quite a few other bulk locations and pumps in Germany)
...it's not taxed as fuel, considered to be the same benefits, more or less as biodiesel, whereas petrodiesel is heavily taxed, so of the three new oil (SVO) is the cheapest (and maybe overall, also the least subsidized?!) In Canada and the USA, of course, new oil is still more money than diesel fuel, but actually the gap is closing, so perhaps it's possible for more people to start looking at greater use of new, cold pressed oils (not soy) here, or perhaps at least looking at a blend of new oil (Costco Canola, or Sunflower) and good WVO, as a cost-effective and technically better option than just using WVO. If it's affordable, do it, I would have to say, and especially if your best local option for WVO, after really checking around, is still not so good. Blending with new oil will thin the WVO, and the cold pressed is nice - also the new food grade oil (not cold pressed) maybe has a few advantages, as well. It has after all been degummed, bleached, deodorized, winterized - the Wonder Bread of cooking oils...Not so tasty, but good for a fryer and pretty good stuff for blending with WVO, IMHO, for reduced viscosity, FFA compensation/correction to closer to neutral pH, etc. New cold pressed high oleic sunflower and WVO, 50/50, would be good. Also it would be good to see more happening with Camelina Sativa (false flax, pleasure-of-gold), since it can be grown in the same field at the same time as other crops (peas for example) eliminating the use of herbicide via it's shading/weed suppression between rows, and you can get the same yield of peas as always, produce both oil energy crop and field crop, and get a light oil suitable for blending and helpful in cold weather. And BTW, the level of sophistication and engineering that you mentioned is proportionate to the type of conversion: - extended time glow plugs would be single tank, yes. Not needed for two-tank. - injector modifications and rechipping or other modification of the fuel injection computer would be needed in some instances, not in others. What *is* needed for all conversions, we feel, and what we provide with our kits, is a very large filter area, for long filter element life, and cost effectively done, *even when* using WVO that has not been pre-filtered Also, for the WVO, a water separator is a very good idea, of course (integrated into the onboard fuel processor is even better, since it's then compact and easily installed - that's what we provide) - a robust, solid state electric heater with enough output to effectively heat the oil to ~ 70C; - a coolant-heated SVO filter; - larger fuel line for the SVO (we now use 1/2" insulhose on all kits, to provide unrestricted flow in all cases), OPTIONALLY, , an extra inline electric heater, a tank heater (electric pad, 12V or 120V, or coolant operated, like our Hotstk); - full-heated-path SVO line, and so on. The requirements for the optional items vary with the application. How well single tank systems will work depends on the level of conversion done, the options used, the oil used, the climate, and the engine type. We are doing some single tank systems, just looking into doing single tank TDi, especially in California and other places where the climate and the availability of good liquid WVO or "flush oil" from the large food oil processors will support that application. The warm climate will help you next winter, Bruce, but I think it's going to be important to realize the need for oil that will stay liquid and combust easily with that system. It's not the same at all, trying to start an engine on a nice light new oil, versus some partly hydrogenated WVO...the degree of degradation will be even more important to be aware of. keep us all posted, and let us know when you've topped Alex's numbers! cheers, Edward Beggs http://www.biofuels.ca On Thursday, May 13, 2004, at 09:51 AM, Bruce Colley wrote: > Ed- > It is a single tank system.
