Comparative study of regulated and unregulated gaseous emissions during NEDC in a light-duty diesel engine fuelled with Fischer Tropsch and biodiesel fuels

Bermúdez, Vicente; Luján, José M.; Plá Moreno, Benjamín; Linares Rodríguez, Waldemar Gregorio (Elsevier, 2011-02)

In this study, regulated and unregulated gaseous emissions and fuel consumption with five different fuels were tested in a 4-cylinder, light-duty diesel EURO IV typically used for the automotive vehicles in Europe. Three ...
Control-oriented modelling and diagnostics of diesel after-treatment catalysts

Mora Pérez, Javier (Universitat Politècnica de València, 2019-01-21)

[ES] Esta tesis doctoral abarca el desarrollo de algoritmos orientados a mejorar el sistema de control de emisiones en motores Diesel. Para este propósito, la inclusión en el vehículo de sensores embarcados como los de ...
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 ...
Experimental determination and modelling of the diesel oxidation catalysts ageing effects

Guardiola, Carlos; Pla Moreno, Benjamín; Mora Pérez, Javier; Lefebvre, Damien (SAGE Publications, 2019-10)

[EN] After-treatment systems are necessary to respect the pollutant emissions thresholds specified by regulations. However, due to system ageing, the efficiency of the after-treatment system may decrease and affect the ...
Fast estimation of diesel oxidation catalysts inlet gas temperature

Guardiola, Carlos; Dolz García, Vicente Manuel; Plá Moreno, Benjamín; Mora-Pérez, Javier (Elsevier, 2016-11)

With the tightening of on-board diagnostics requirements, accuracy of sensors is essential to monitor the efficiency and ensure a proper control of the after-treatment systems. Temperature sensors are commonly used in the ...
Model-based passive and active diagnostics strategies for diesel oxidation catalyst

Guardiola, Carlos; Plá Moreno, Benjamín; Piqueras, P.; Mora-Pérez, Javier; Lefebvre, D. (Elsevier, 2017)

[EN] This article proposes a diesel oxidation catalyst diagnostics strategy based on the exothermic process generated by exhaust gas species oxidation in the catalyst. The diagnostics strategy is designed to be applied ...
Performance of a diesel oxidation catalyst under diesel-gasoline reactivity controlled compression ignition combustion conditions

Piqueras, P.; García Martínez, Antonio; Monsalve-Serrano, Javier; Ruiz, María José (Elsevier, 2019-09-15)

[EN] Reactivity controlled compression ignition is a promising combustion strategy due to the combination of excellent thermal efficiency with ultra-low nitrogen oxides and particulate matter raw emissions. However, very ...
