Bio-Diesel Fuel

Bio-diesel fuel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Bio-diesel can be used alone, or blended with petroleum diesel. Bio-diesel can also be used as a low carbon alternative to heating oil.

Bio-diesel has better lubricating properties and much higher *cetane ratings than today’s lower sulfur diesel fuels. Bio-diesel addition reduces fuel system wear,and in low levels in high pressure systems increases the life of the fuel injection equipment that relies on the fuel for its lubrication. Depending on the engine, this might include high pressure injection pumps, pump injectors (also called unit injectors) and fuel injectors.

*Cetane number (or CN) is an indicator of the combustion speed of diesel fuel.
