Mora Pérez, Javier (Universitat Politècnica de València, 2014-11-05)

Proyecto confidencial (Riunet)
An on-board method to estimate the light-off temperature of diesel oxidation catalysts

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Mora, Javier (SAGE Publications, 2020-10)

[EN] Current diesel engine regulations include on-board diagnostic requirements so that after-treatment systems need on-board methods to detect their aging state through the available measurements. In a state-of-the-art ...
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 ...
Desarrollo de Técnicas de diagnóstico a bordo para catalizadores de oxidación diesel

Mora Pérez, Javier (Universitat Politècnica de València, 2016-07-22)

[EN] Present work develops on-board diagnostics (OBD) techniques for diesel oxidation catalysts (DOC). As computational resources in modern electronic control units (ECU) are scarce, algorithms must consider the time ...
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 Ammonia Slip Observation for SCR Control and Diagnosis

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Mora, Javier (Institute of Electrical and Electronics Engineers, 2020-06)

[EN] The control of selective catalytic reduction (SCR) systems, via NH3 injection, requires from a precise estimation of the SCR load in order to ensure NOx reduction by minimizing ammonia slip. This article aims to resolve ...
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 ...
