Bio diesel – group project
Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel. Biodiesel 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. Biodiesel can be used alone, or blended with petro diesel. Biodiesel has better lubricating properties and much higher octane ratings than today's lower sulfur diesel fuels. Biodiesel 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 and fuel injectors. Biodiesel has been known to break down deposits of residue in the fuel lines where petro diesel has been used. As a result, fuel filters may become clogged with particulates if a quick transition to pure biodiesel is made. Therefore, it is recommended to change the fuel filters on engines and heaters shortly after first switching to a biodiesel blend. In 2007, in the United States, average retail prices, including federal and state fuel taxes, of B2 and B5 were lower than petroleum diesel by about 12 cents, and B20 blends were the same as petro diesel. However, as part as a dramatic shift in diesel pricing, by July 2009, the US DOE was reporting average costs of B20 15 cents per gallon higher than petroleum diesel making it $2.69 per gallon versus $2.54 per gallon. There are many different application of biodiesel also use in vehicle. In 2005, Chrysler released the Jeep Liberty CRD diesels from the factory into the American market with 5% biodiesel blends, indicating at least partial acceptance of biodiesel as an acceptable diesel fuel additive. In 2007, DaimlerChrysler indicated its intention to increase warranty coverage to 20% biodiesel blends if biofuel quality in the United States can be standardized. British train operating...
