The influence of this renewable additive in both the engine performance and the produced emissions was evaluated. Five more fuels were used for the sake of comparison: petroleum diesel, neat sunflower biodiesel without additives, commercial biodiesel, commercial B10 blend and another B10 blend prepared from petro-diesel and doped sunflower biodiesel. Brake power was found to be similar for the six fuels, while the brake specific fuel consumption and the brake thermal efficiency were higher for biodiesel fuels. Only slight differences (<1%) were observed between the doped biodiesel and the neat one, showing that the bio-oil based additive did not negatively affect the general performance of the engine. Regarding gas emissions (analysed according to the European Stationary Cycle), weighted average emissions of NOx and CO2 were higher for biodiesel fuels, while CO and opacity factor were lower in that case. Incorporating the bio-oil based additive reduced NOx emissions and smoke opacity by 3.0% and 4.4% compared with neat biodiesel, respectively, whilst CO and HC emissions increased by 0.7 and 14.3% respectively, values still remaining below those of diesel. info:eu-repo/grantAgreement/ES/MINECO/FPDI-2013-17351 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.128 2018 ENGINEERING, CHEMICAL 13 / 138 = 0.094 2018 Q1 T1 ENERGY & FUELS 20 / 103 = 0.194 2018 Q1 T1 1.745 2018 Chemical Engineering (miscellaneous) 2018 Q1 Organic Chemistry 2018 Q1 Fuel Technology 2018 Q1 Energy Engineering and Power Technology 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-7893-698X Muñoz, Mariano Universidad de Zaragoza (orcid)0000-0002-6508-6998 Moreno, Francisco Universidad de Zaragoza (orcid)0000-0003-3157-6267 Arroyo, Jorge Universidad de Zaragoza (orcid)0000-0002-8704-9274 Gil-Lalaguna, Noemí Universidad de Zaragoza Bautista, Ana Gonzalo, Alberto (orcid)0000-0002-9705-2207 Sánchez, José Luis Universidad de Zaragoza 5005 555 Universidad de Zaragoza Dpto.
