Analysis of the high pressure EGR dispersion among cylinders in automotive diesel engines

Miguel García, Julián (Universitat Politècnica de València, 2021-02-19)

[ES] Los objetivos son 2: 1- Determinar el efecto de la dispersión de la recirculación de gases de escape de alta presión (HP EGR) en las emisiones de NOx y humos en motores diésel de automoción en operaciones de funcionamiento ...
Control no lineal de velocidad y aire alimentado en un motor diésel con turbocompresor y recirculación de gases de escape

Mendoza-Soto, José Luis; Álvarez-Icaza, Luis; Rodríguez Cortés, H. (Universitat Politècnica de València, 2019-09-20)

[EN] A non-linear control to regulate the speed and the supply of air flow in an internal combustion Diesel engine with exhaust gas recirculation system is proposed. The control scheme uses a static feedback of the states ...
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 ...
Estudio experimental de un sistema de recirculación de gases de escape de baja presión integrado en la entrada del compresor de un motor de encendido provocado sobrealimentado

Najarro Pastor, Adrián (Universitat Politècnica de València, 2024-11-13)

[ES] La recirculación de gases de escape de baja presión permite mejorar el balance entre rendimiento y emisiones contaminantes en motores de encendido provocado. No obstante, en condiciones de arranque en frío parte del ...
High-pressure exhaust gas recirculation line condensation model of an internal combustion diesel engine operating at cold conditions

Luján, José M.; Dolz, Vicente; Monsalve-Serrano, Javier; Bernal-Maldonado, Miguel Angel (SAGE Publications, 2021-02)

[EN] To fulfill the future NOx emission regulations, the use of exhaust gas recirculation could be necessary for the engine starting at cold conditions. In this context, condensation inside the exhaust gas recirculation ...
Impact of Exhaust Gas Recirculation on Gaseous Emissions of Turbocharged Spark-Ignition Engines

Piqueras, P.; De La Morena, Joaquín; Sanchis-Pacheco, Enrique José; Pitarch-Berná, Rafael (MDPI AG, 2020-11)

[EN] Exhaust gas recirculation is one of the technologies that can be used to improve the efficiency of spark-ignition engines. However, apart from fuel consumption reduction, this technology has a significant impact on ...
Numerical study of EGR mixing and distribution in a piston engine intake line

García Olivas, Guillermo (Universitat Politècnica de València, 2022-01-10)

[ES] Teniendo en cuenta la cantidad de motores de combustión interna que se encuentran en activo actualmente, y sus potenciales emisiones de contaminación si se realizaran de forma incontrolada por el parque automovilístico, ...
On the combination of high-pressure and low-pressure exhaust gas recirculation loops for improved fuel economy and reduced emissions in high-speed direct-injection engines

Desantes Fernández, José Mª; Luján, José M.; Plá Moreno, Benjamín; Soler Muniesa, José Antonio (SAGE Publications (UK and US), 2013)

In this paper, an experimental study of the combination of low-pressure and high-pressure exhaust gas recirculation architectures has been carried out. In the first part of the paper, the effects of both high-pressure and ...
Optimizing hydrogen spark-ignition engine performance and pollutants by combining VVT and EGR strategies through numerical simulation

Novella Rosa, Ricardo; Gómez-Soriano, Josep; González-Domínguez, David; Olaciregui-Fontalvo, Orlando Mario (Elsevier, 2024-12-15)

[EN] Hydrogen combustion engines are considered one of the leading solutions for decarbonizing road transport, mainly due to the possibility of adapting current engines for hydrogen operation with minor changes. This ...
Transient behaviour of a turbocharged, direct injection, spark ignited engine with low pressure exhaust gas recirculation

Pitarch Berná, Rafael (Universitat Politècnica de València, 2020-12-21)

[ES] La adición de EGR en motores de gasolina puede ser beneficiosa desde el punto de vista de la eficiencia. Esto se debe a la reducción de las pérdidas de calor asociadas al incremento de los calores específicos en ...
