Somewhat related, and useful in any case: Ethanol blended diesel (e-diesel) is a cleaner burning alternative to regular diesel for both heavy-duty (HD) and light-duty (LD) compression ignition (CI) engines used in buses, trucks, off-road equipment, and passenger cars. Although ethanol has been used as a fuel oxygenate to reduce tail-pipe emissions in gasoline, its use in diesel has not been possible due to technical limitations (i.e., blending). Commercially viable E-Diesel is now possible due to the development of an additive system, Puranol, invented by Pure Energy Corporation (PEC). Puranol allows the splash blending of ethanol in diesel in a clear solution possible for the first time. Laboratory and field tests have demonstrated over 41% reduction in PM, 27% reduction in CO, and 5% reduction in NOx from a HD diesel engine. Significantly higher emissions reductions are observed from smaller 1.9-L VW TDI engines. Six page pdf: http://www.pure-energy.com/sae2001-01-2475.pdf

We collect recycled vegetable oil for our members for use as fuel for their converted diesel vehicles.

There is a necessary modification using the Elsbett or Neoteric kits before the diesel car can run on pure veggie. As you know, biodiesel can be run directly in an unmodified diesel engine. The required step, however, is the modification of the veggie oil before it can be used as fuel. > > So the two options present themselves: 1. Modify the diesel engine, or 2. Modify the fuel (veggie oil). If an ethanol-veggie blend can work then we can bypass the modification of the engine. However, I fear that a diesel engine may not take very kindly to having ethanol introduced into it, even if it is blended with veggie oil. The BRC has chosen the route of modifying the engine but if the ethanol-veggie blend works then there is no need to go through the hassle and expense of adapting the diesel motor to the alternative fuel. I can see myself producing ethanol at home with a still to later mix with my pure veggie oil. > > Any response will be appreciated, > > Edward Mendoza > [EMAIL PROTECTED] > 707.537.7392 > 211 Hayman Court > Santa Rosa, CA 95409 Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://archive.nnytech.net/index.php?list=biofuel Please do NOT send Unsubscribe messages to the list address.
