Bio diesel- the Clean, Green Fuel for Diesel Engines

Natural, renewable resources such as vegetable oils, animal fats and recycled restaurant greases can be chemically transformed into clean burning bio diesel fuels (1). Just like petroleum diesel, bio diesel operates in combustion-ignition engines. Blends of up to 20% bio diesel (mixed with petroleum diesel fuels) can be used in nearly all diesel equipment and are compatible with most storage and distribution equipment. Using bio diesel in a conventional diesel engine substantially reduces emissions of unburned hydrocarbons, carbon monoxide, sulphates, polycyclic aromatic hydrocarbons, nitrated polycyclic aromatic hydrocarbons, and particulate matter. The use of bio diesel has grown dramatically during the last few years. Egypt has a promising experiment in promoting forestation by cultivation of Jatropha plant especially in luxor and many other sites of the country. The first production of the Egyptian Jatropha seeds oil is now under evaluation to produce a cost-competitive bio diesel fuel
