Advantages of biodiesel
Disadvantages of biodiesel
Successful alternative fuels, fulfill environmental and energy needs without sacrificing operating performance. Operationally, biodiesel performs very similar to low sulfur diesel in terms of power, torque, and fuel without major modification of engines or infrastructure.
One of the major advantages of biodiesel is the fact that it can be used in existing engines and fuel injection equipment with little impact to operating performance. Biodiesel has a higher cetane number than U.S. diesel fuel. In over 15 million miles of in-field demonstrations biodiesel showed similar fuel consumption, horsepower, torque, and haulage rates as conventional diesel fuel.
Biodiesel provides significant lubricity improvement over petroleum diesel fuel.
Lubricity results of biodiesel and petroleum diesel using industry test methods indicate that there is a marked improvement in lubricity when biodiesel is added to conventional diesel fuel. Even biodiesel
levels below 1 percent can provide up to a 65 percent increase in lubricity in distillate fuels.
Compatibility of biodiesel with engine components.
The recent switch to low sulfur diesel fuel has caused most OEMs to switch to components suitable for use with biodiesel, but users should contact their OEM for specific information. In general, biodiesel will soften and degrade certain types of elastomers and natural rubber compounds over time. Using high percent blends can impact fuel system components (primarily fuel hoses and fuel pump seals), that
contain elastomer compounds
incompatible with biodiesel. Manufacturers recommend that natural or butyl rubbers
not be allowed to come in contact with pure biodiesel. Biodiesel will lead to
degradation of these materials over time, although the effect is lessened with biodiesel
blends. If a fuel system does contain these materials and users wish to fuel with pure
biodiesel, replacement with compatible elastomers is recommended.
Biodiesel in cold weather.
Cold weather can cloud and even gel any diesel fuel,
including biodiesel. Users of a 20 percent biodiesel blend will experience an increase
of the cold flow properties (cold filter plugging point, cloud point, pour point) of
approximately 3 to 5° Fahrenheit. Precautions employed for petroleum diesel are
needed for fueling with 20 percent blends. Neat (100 percent) biodiesel will gel faster
than petrodiesel in cold weather operations. Solutions for winter operability with neat
biodiesel are much the same as that for low-sulfur #2 diesel (i.e., blending with #1
diesel, utilization of fuel heaters, and storage of the vehicle in or near a building).
These same solutions work well with biodiesel blends, as do the use of cold flow
The web is loaded with information about biodiesel. Use your search engine and you will get websites covering every aspect of subject. There is no point in re-creating this information. Our purpose is to make sure that you understand that although biodiesel is operationally the same as petroleum diesel fuel, not all biodiesel fuel is created equal and unless you use a high quality biodiesel that meets ASTM standards there is no guarantee that biodiesel won't damage your engine resulting in costly repairs.
