- Abstract
- In the last years, increasing attention has been paid to biofuels for their potential to reduce both CO2 emissions,
considered one of the major greenhouse gas (GHG), and particulate matter mass emissions. Biodiesel can be classified
in 1st and 2nd generation fuels. First generation biodiesel is produced from vegetable oils and animal fats through a
transesterification process. The 2nd generation of alternative fuel was obtained from the well-known Fischer-Tropsch
synthesis process. The physical properties and chemical composition of biofuels are quite similar with respect to the
conventional diesel fuel even if they can alter the combustion processes in terms of performance and emissions.
In this paper, the effect of the alternative diesel fuels on particle formation and emissions was analyzed by means of
optical techniques and conventional methods. The measurements were carried out on a direct injection (DI) Common
Rail (CR) transparent research diesel engine. In-cylinder broadband UV-visible measurements were used to acquire
information about the soot size distribution. The particulate emissions were characterized at the exhaust by means of an
electrical low pressure impactor (ELPI), for the particle counting and sizing, and an opacimeter, for the smoke opacity
(particulate mass concentration) measurement. The engine was fuelled with conventional diesel and two alternative
fuels, chosen as representative of the first generation biofuel, namely RME, and second generation biofuel, GTL, at two
engine operating conditions,1500 rpm x 2 bar and 2000 rpm x 5 bar of BMEP, typical of New European Driving Cycle. (literal)
