Биодизелът е биогориво, произведено от растителни масла или животински мазнини. Той притежава характеристики, близки до тези на петролния дизел и се смята за особено подходящ като гориво за стандартните дизелови двигатели, без да са необходими допълнителни модификации. Биодизелът подобрява работата на двигателя, увеличава мощността му, не съдържа сяра, намалява разхода на гориво и не на последно място, биодизелът е по-евтин от конвенционалния дизел, тъй като не се облага с акциз. Това е най-перспективното и екологично чисто гориво. Биодизелът може да се използва в чист вид и като добавка към обикновения дизел.

The use of biodiesel in a conventional diesel engine results in substantial reduction of unburned hydrocarbons, carbon monoxide and particulate matter. The exhaust emissions of sulfur oxides and sulfates (major components of acid rain) from biodiesel are essentially smaller compared to petrodiesel. Scientific research confirms that biodiesel exhaust has a less harmful impact on human health than petroleum diesel fuel. Biodiesel emissions have decreased levels of polycyclic aromatic hydrocarbons (PAH) and nitrited PAH compounds which have been identified as potential cancer causing compounds. In recent testing, PAH compounds were reduced by 75% to 85%, with the exception of benzoanthracene, which was reduced by roughly 50%. Targeted nPAH compounds were also reduced dramatically by using biodiesel fuel, with 2-nitrofluorene and 1-nitropyrene reduced by 90%, and the rest of the nPAH compounds reduced to only trace levels. Biodiesel is the name of a clean burning methanol (mono-alkyl) ester- or ethanol ester based fuel made from vegetable or animal fats. Biodiesel can be blended with petro- diesel in any relation. It can be used in diesel engines without modification. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulphur and aromatics. Biodiesel can be operated in any diesel engine with little or no impact to the fuel system. Biodiesel has a solvent effect which may release deposits accumulated on tank walls and pipes from previous diesel fuel storage. The release of deposits may clog filters. Biodiesel can be used as a pure fuel or blended with petroleum in any ratio. The politics of car producers are different, e.g., all production models since production year 1996 are fully equipped and rated for biodiesel use. Mercedes Benz delivers biodiesel equipped cars upon request. For other cars, please check with the manufacturer. Biodiesel can be used instead of mineral diesel in any car or truck. Only the compatibility of fuel pumps and seals has to be ensured. Due to high viscosity of rapeseed oil it must be heated to 75 °C in order to be compBatible with standard injection pumps. Biodiesel has a higher cetane number than 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. WHAT IS BIO-DIESEL: Biodiesel can, in theory, be used in all diesel engines. However, due to the parts attached to the diesel engine, some manufacturers do not approve engines running on 100% biodiesel. Biodiesel’s chemical name is "Fatty-Acid Methyl Ester". This fancy name means it is a simple molecule made from vegetable oil. This fuel has a high energy content and a proper viscosity “willingness to flow” to be used in all diesel vehicles and equipment. It’s made from a naturally grown crop making its energy from the sun. What is NOT Biodiesel Look Carefully! Many companies and groups improperly use the word biodiesel to describe diesel fuel replacement products they have developed. This creates significant confusion for consumers looking to purchase and use biodiesel. Some of these alternatives have not been properly tested and could lead to damage to vehicles. Below is some information to help distinguish real biodiesel from imposters. What biodiesel IS NOT: • Biodiesel is not vegetable oil. • Biodiesel is not vegetable oil diluted with solvents, i.e. diesel fuel or alcohols. • Biodiesel is not vegetable oil with “special additives” to make it run better. • Biodiesel is not vegetable oil refined through a conventional oil refinery process. • Biodiesel is not vegetable oil refined through thermal depolymerization (renewable diesel). • Biodiesel is not a fuel that requires costly modifications to your diesel engine (straight vegetable oil). • Biodiesel is not crude methyl esters which have not been refined or minimally refined. Unlike biodiesel, none of the fluids listed above have undergone renewable fuel certification, emissions or toxicity testing, or long-term reliability testing in engines and vehicles. biodiesel-7666-LS5ej57.docx (62 KB) biodiesel-7666-LWLnusk.ppt (950 KB)
