Biodiesel is the
name of a
clean-burning alternative fuel, produced from domestic, renewable resources. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel is
simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics.
TECHNICAL DEFINITIONS-Biodiesel, n - a fuel composed of
mono-alkyl esters of long chain fatty acids derived from vegatable oils or
animal fats, designated B100, and meeting the requirements of ASTM (American
Society for Testing & Materials) D 6751.
Biodiesel can be operated in any diesel engine with little or no modification to the engine or the fuel
system. Biodiesel has a solvent effect that may release deposits accumulated on
tank walls and pipes from previous diesel fuel storage. The release of deposits may
clog filters initially and precautions should be taken. Ensure that only fuel meeting the biodiesel specification (D 6751) is used.
Biodiesel has the highest "energy balance" of any current
transportation fuel. The
DOE/USDA lifecycle analysis shows for every unit of fossil energy it takes to make biodiesel, 3.2 units of energy are gained. This takes into account the planting, harvesting, fuel production and fuel transportation to the end user.
