dc.description.abstract | The aim of the study was to assess the influence of the addition of an oxygenated additive
(a mixture of mono-, di- and triacetylglycerol obtained from residual glycerin within the biodiesel
production scheme) on the specific fuel consumption and exhaust emissions of a EURO 3 diesel bus
during its daily route through the city. To do this, the urban bus was fuelled with five fuel blends
of diesel (D), biodiesel (B), additive (A) and heptanol as co-surfactant (H). A portable emissions
measurement system was used to measure the exhaust gases while an engine exhaust particle system
with a dilution system, both installed on the urban bus, was used for nanoparticles measurement in
actual operating conditions through the city of Seville. Results showed that B95A5 (95%v/v biodiesel,
5%v/v additive) and B90A10 were the blends that most increased NOx emissions (by 24.12% and
9.85%, respectively) compared to D100. On the other hand, B47.5D47.5A2.5H2.5 was the blend that
most reduced total particle number (by 31.6%) and NOx emissions (by 12%). All in all, the oxygenated
additive can be efficiently blended with biodiesel to reduce particle emissions from engines without
diesel particle filter, such as those in urban buses in many European cities. | es |
