Abstract : Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, propyl or ethyl) esters.

Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, animal fat) with an alcohol.

Biodiesel production is a modern and technological area for researchers due to constant increase in the prices of petroleum diesel and environmental advantages.

The use of fatty acids methyl esters either in mixtures with fossil diesel or in pure state in diesel engines is correlated to a series of technical problems which are to be taken into account in order to not spoil the important environmental and social advantages that this kind of bio-combustibles reports.

Throughout this work, the most critical aspects of biodiesel use as well as their immediate consequences are introduced.

In general, this work tries to be a guide, which allows identifying the most sensible areas within the engine, as well as the suitable means and solutions for the correct use of biodiesel in compression ignition engines (diesel engines).
