The utilization of biofuels in diesel engines is a promising alternative
to diversify and to replace either all or partially fossil diesel with no
changes in engine design. In addition, an important feature of the use
of biofuels is that their performance is similar to or better than that of
diesel.
Biofuels have become important as energy sources due to several
reasons: their use contributes to reducing greenhouse gas emissions
[1,2] and petroleum oil dependence and minimizing fossil fuel consumption
[4]. In addition, they are renewable and rural income generating [3].
Among the biofuels potentially available, biodiesel and bioethanol
are the main and current renewable liquid fuels. However, biofuels
have significant potential for expansion and there has been increasing
interest in renewable fuel production, in addition, the co-combustion
of renewable and fossil fuels has generated widespread interests in
both environmental and economical aspects.
A family of hydrocarbons, the isoprenoids, are being developed for
biofuel applications principally by Amyris Inc. (NASDAQ: AMRS), which
has a patent on farnesane (a C15 isoprenoid) [5]. Amyris constructed in
late 2008 a pilot plant in USA (Emeryville, Ca) with a 9 million L/year
capacity and also has a pilot plant in Brazil (Campinas, SP), which is
still in the development and demonstration phase [6].
Farnesane is a biomass-derived fuel produced from sugarcane syrup
using genetically and metabolically engineered yeast and is becoming
increasingly attractive for use in diesel engines. Commercially farnesane
can be found as a renewable diesel from sugar.
When a new technology is proposed, and there is no sufficient information
available, the effect of several conditions should be investigated,
therefore it is important that the new technology have a
behavior similar or better than diesel fuel without any modification
of combustion chamber design or engine
