The development of biofuels for compression ignition engines is heading primarily to
utilization of vegetable oils.
Combusting of 100% vegetable oil in unmodified CI engine is
usually not possible due to higher viscosity of the vegetable oil. In order to use 100% vegetable
oil in CI engine the oil needs to be preheated, esterified or hydrotreated. Alternatively, in orde
r
to use raw vegetable oil in CI engine without preheating it is possible to use vegetable oil

diesel
fuel blends or vegetable oil

butanol
–
diesel fuel blends in order to lower the viscosity of the
fuel. The contribution focuses on comparison of the e
ffect of sunflower and rapeseed vegetable
oils on operational parameters of the turbocharged compression ignition engine, especially on
production of solid particles.
The measurement was carried out according to standardized NRSC
test cycle. 5% and 20% con
centration of vegetable oils in diesel fuel were used as a test fuels for
the measurement while the diesel fuel was used as a reference. The count and size of solid
particles were measured by means of EEPS particle analyser. Based on the measured values it
can be stated that the slight increase of performance parameters occurred with strong effect on
emissions production, especially on production of solid particles.
