A Comprehensive Study of Particle Size Distributions with the Use of PostInjection Strategies in DI Diesel Engines

Desantes, J.M.; Bermúdez, Vicente; García Martínez, Antonio; Linares Rodríguez, Waldemar Gregorio (Taylor & Francis, 2011)

[EN] Control strategies such as variations in injection pressure and timing have been used by researchers to reduce in-cylinder exhaust emissions and meet legislation standards. Postinjection has been studied for several ...
Effects of low pressure exhaust gas recirculation on regulated and unregulated gaseous emissions during NEDC in a light-duty diesel engine

Bermúdez, Vicente; Luján, José M.; Plá Moreno, Benjamín; Linares Rodríguez, Waldemar Gregorio (Elsevier, 2011-09)

Regulated and unregulated gaseous emissions with high pressure and low pressure EGR (exhaust gas recirculation) system were tested in a 4-cylinder, light-duty diesel EURO IV engine typically used in European vehicles. Four ...
Heat transfer modelling in honeycomb wall-flow diesel particulate filters

Galindo, José; Serrano Cruz, José Ramón; Piqueras, P.; García Afonso, Óscar (Elsevier, 2012-07)

Heat transfer in wall-flow monoliths has gained in interest because of the widespread adoption of these systems by automotive industry to fulfil soot emission regulations and the importance of heat exchange on the regeneration ...
Methodology for measuring exhaust aerosol size distributions using an engine test under transient operating conditions

Desantes, J.M.; Bermúdez, Vicente; Molina, Santiago; Linares Rodríguez, Waldemar Gregorio (IOP PUBLISHING LTD, 2011)

[EN] A study on the sources of variability in the measurement of particle size distribution using a two-stage dilution system and an engine exhaust particle sizer was conducted to obtain a comprehensive and repeatable ...
The role of in-cylinder gas density and oxygen concentration on late spray mixing and soot oxidation processes

Benajes Calvo, Jesus Vicente; Novella Rosa, Ricardo; García Martínez, Antonio; Arthozoul ., Simon Jean Louis (Elsevier, 2011)

An analysis of in-cylinder gas density and oxygen mass concentration (YO 2) impact on the mixing and oxidation processes and the final soot emissions in conventional high temperature diffusive Diesel combustion conditions ...
