New European Driving Cycle assessment by means of particle size distributions in a light-duty diesel engine fuelled with different fuel formulations
In this study, an experimental investigation of particle size distribution emission over performance of transient
conditions in a high speed diesel engine fuelled with diesel, biodiesel and Fischer Tropsch fuels have been assessed.
Six fuels with different properties have been tested in a 4-cylinder light-duty diesel engine typically used for European
passenger cars. The cycle used in this study was the New European Driving Cycle (NEDC) and each test was carried
out after a stabilization warming period in order to avoid cold start effects. A comparative analysis between nucleation
and accumulation particle mode concentration, particle size distributions and a geometric mean diameter calculation
are presented in this paper. In this sense, a reduction in the range of particle diameter emitted and a decrease in
accumulation particle mode concentration with Fischer Tropsch fuel during the EUDC were found. In contrast, all
biofuels used show an increase of particle number concentration in nucleation-mode during the urban cycles (ECE-15)
related to combustion damage at low load conditions. Finally, an increase in the sulfur content diesel fuel leads to an
increase in the geometric mean diameter of particle size distribution related to the increase in accumulation particle
concentration during the entire cycle.The equipment used in this work has been partially supported by FEDER project funds "Dotacion de infraestructuras cientifico tecnicas para el Centro Integral de Mejora Energetica y Medioambiental de Sistemas de Transporte (CiMeT), (FEDER-ICTS-2012-06)'', framed in the operational program of singular scientific and technical infrastructure of the Ministry of Science and Innovation of Spain.Bermúdez Tamarit, VR.; Lujan Martinez, JM.; Ruiz Rosales, S.; Campos, D.; Linares RodrÃguez, WG.
