Facts

We have gathered interesting facts involving the environment and of course, biodiesel.

  • The Diesel engine was invented in 1897 and originally ran on peanut oil.
  • Biodiesel has been widely used in Europe for over 10 years.
  • Children riding inside diesel school buses are exposed to as much as 4 times the level of toxic exhaust as people outside of the bus.
  • It is estimated that half of all air pollution in the US and up to 71% in the LA air basin, is due to the petroleum diesel emissions.
  • Estimated Annual US Pertroleum Diesel Consumption is 70 billion gallons. More than half of that is for transportation.
  • Engine efficiency determines how may miles per gallon your vehicle gets. Gasoline engines have an efficiency rating of 25, while diesel engines have an efficiency rating of 40, which means diesel gets up to 60% better fuel economy than gasoline.
  • Cetane (ignition quality) ratings for diesel is similar to octane ratings for gasoline: Petroleum diesel = 40; Recycled Feedstock biodiesel = 55.
  • Biodiesel has an ASTM specification, D 6751, which covers low sulfur biodiesel (B100) for use as a blend component with diesel fuel oils defined by Specification D 975 Grades 1-D, 2-D, and low sulfur 1-D and 2-D.
  • Biodiesel reduces air toxins by up to 90% and does not contribute to sulfur dioxide emissions.
  • Biodiesel has the highest energy balance of any fuel. For every unit of fossil energy needed to produce biodiesel, 3.2 units of energy are gained.
  • Biodiesel has significantly improved lubricity, which can decrease maintenance costs and reduce engine wear.
  • Biodiesel can be operated in any diesel engine with little or no modification to the engine for the fuel system. In biodiesel blends over 20%, biodiesel has a solvent effect, which may release deposits accumulated on tank walls and pipes from previous diesel fuel. The release of deposits may clog filters initially and precautions should be taken.

B20 BioDiesel Facts

  • B20 is a blend of 20% biodiesel and 80% diesel fuel, which:
  • Provides optimum emission benefits for the lowest cost.
  • Keeps NOx increase small (1-4%) and within legal emission limits for engines. (NOx can be reduced further by changing engine timing.).
  • Offers excellent emission benefits by reducting soot, particulates, hydrocarbons, carbon monoxide, and carbon dioxide by more than 10% each.
  • Minimal increases in cloud and pour point levels can be easily managed by additives.
  • Does not contribute to sulfur dioxide emissions.
