Application of dynamic optimization and data fusion techniques for SCR control

Nakaema Aronis, André (Universitat Politècnica de València, 2020-12-19)

[ES] Los sistemas de postratamiento SCR son la solución más extendida para la reducción de emisiones de NOx en motores Diesel de automoción, pues permiten reducciones en las emisiones de NOx de hasta el 95%. En los últimos ...
Assessing the optimum combustion under constrained conditions

Olmeda, P.; Martín, Jaime; Novella Rosa, Ricardo; Blanco-Cavero, Diego (SAGE Publications, 2020-06-01)

[EN] This work studies the optimum heat release law of a direct injection diesel engine under constrained conditions. For this purpose, a zero-dimensional predictive model of a diesel engine is coupled to an optimization ...
Development of a control-oriented model to optimise fuel consumption and NOX emissions in a DI Diesel engine

Molina, Santiago; Guardiola, Carlos; Martín Díaz, Jaime; García Sarmiento, Daniel (Elsevier, 2014-04-15)

This paper describes a predictive NOX and consumption model, which is oriented to control and optimisation of DI Diesel engines. The model applies the Response Surface Methodology following a two-step process: firstly, the ...
EGR transient operations in highly dynamic driving cycles

Galindo, José; Climent, H.; Pla Moreno, Benjamín; Patil, Chaitanya Yashvant (Springer-Verlag, 2020-08)

[EN] EGR is one of the proven and well tested strategies within the specific operating range of the engine. Necessity of an implementation of this exhaust gas recirculation all over the engine operating range is emerging. ...
Exhaust gas recirculation dispersion analysis using in-cylinder pressure measurements in automotive diesel engines

Luján, José M.; Climent, H.; Plá Moreno, Benjamín; Rivas Perea, Manuel Eduardo; Francois, Nicolas-Yoan; Borges Alejo, José; Soukeur, Zoulikha (Elsevier, 2015-10-05)

Current diesel engines are struggling to achieve exhaust emissions regulations margins, in certain cases penalizing the fuel consumption. The exhaust gas recirculation (EGR) continues to be employed as a technique to reduce ...
Identifying static and dynamic prediction models for NOx emissions with evolving fuzzy systems

Lughofer, Edwin; Macian Martinez, Vicente; Guardiola García, Carlos; Klement, Erich Peter (Elsevier, 2011-03)

Antipollution legislation in automotive internal combustion engines requires active control and prediction of pollutant formation and emissions. Predictive emission models are of great use in the system calibration phase, ...
Modelling and evaluation of oxy-combustion and in-situ oxygen production in a two-stroke marine engine

Burgos Quevedo, Paula Rossana (Universitat Politècnica de València, 2023-10-27)

[ES] Teniendo en cuenta la preocupación por la reducción de emisiones en el sector marítimo, el presente trabajo evalúa, mediante modelado y simulación, la oxicombustión en un motor de barco de dos tiempos (2SE) y la mejor ...
Modelling of the injection system and performance at different standard cycles of a new 2-stroke gasoline engine concept

Zahonero Zahonero, Edgar (Universitat Politècnica de València, 2020-01-30)

[EN] In the last years, the world has experienced a decrease in traveling time. Besides, the distance between different cities has been shortened thanks to the technology improvements in terms of transportation. Society ...
Optimal control of a turbocharged direct injection diesel engine by direct method optimization

Luján, José M.; Guardiola, Carlos; Pla Moreno, Benjamín; Reig, Alberto (SAGE Publications, 2019-08)

[EN] This work studies the effect and performance of an optimal control strategy on engine fuel efficiency and pollutant emissions. An accurate mean value control-oriented engine model has been developed and experimental ...
Optimización teórica de la ley de combustión de un motor diésel bajo diferentes estrategias innovadoras

Sellés Tomás, José Manuel (Universitat Politècnica de València, 2018-09-25)

[ES] Actualmente, la preocupación de cualquier persona que posee un automóvil es doble: medioambiental y económica. Esta doble intranquilidad ha conducido al sector de la automoción a definir el estudio de los vehículos ...
