The global search for cleaner energy sources has motivated the development of fuels from oil crops (soybean, sunflower, rapeseed, castor, coconut, palm, etc.), with special importance of biodiesel from African Palm, due to its high yields (5900 l/ha) and decrease of emissions of vehicles (mainly carbon monoxide and volatile hydrocarbons). One of the most important disadvantages of biodiesel is a lower energy output than fossil fuels and consequently requires greater quantities of energy to be consumed in order to produce the
