A complete 0D thermodynamic predictive model for direct injection diesel engines

Payri González, Francisco; Olmeda, P.; Martín Díaz, Jaime; García Martínez, Antonio (Elsevier, 2011-06-01)

[EN] Ideal models provide the simplest way to reproduce internal combustion engine (ICE) cycles, but they usually do not represent with sufficient accuracy the actual behaviour of an ICE. A suitable alternative for research ...
An Investigation of Radiation Heat Transfer in a Light-Duty Diesel Engine

Benajes Calvo, Jesus Vicente; Martín Díaz, Jaime; García Martínez, Antonio; Villalta Lara, David; Warey, Alok; Domenech Llopis, Vicente; Vassallo, Alberto Lorenzo; Vassallo (SAE International, 2015-09)

In the last two decades engine research has been mainly focused on reducing pollutant emissions. This fact together with growing awareness about the impacts of climate change are leading to an increase in the importance ...
Analysis of different approaches for the reduction of NOx in a hydrogen fuelled internal combustion engine.

Más Arroyo, Marcos (Universitat Politècnica de València, 2024-11-13)

[ES] La amenaza que representan el cambio climático y la crisis de seguridad energética ha estimulado la respuesta de los gobiernos, que están poniendo en marcha planes estratégicos para promover la fuentes de energía ...
Application of UV Visible Light Absorption and Scattering technique to low absorption fuels under diesel-like conditions

Pastor Soriano, José Vicente; García Oliver, José María; López, J. Javier; Micó Reche, Carlos (Elsevier, 2016-09-01)

Light Absorption and Scattering technique (LAS) has been applied for the measurement of fuel vapour distribution in diesel-type sprays. This technique is usually limited to fuels with relatively high absorptivity, which ...
Assessment of fuel consumption reduction strategies on a gasoline turbocharged direct injection engine with a cooled EGR system

Rivas Perea, Manuel Eduardo (Universitat Politècnica de València, 2016-09-01)

[EN] This research work presents the study of a low pressure EGR loop influence on a SI gasoline turbocharged direct injection engine in steady and transient testing conditions, with an optimization process of the original ...
DEVELOPMENT OF MEASUREMENT AND VISUALIZATION TECHNIQUES FOR CHARACTERIZATION OF MIXING AND COMBUSTION PROCESSES WITH SURROGATE FUELS

Micó Reche, Carlos (Universitat Politècnica de València, 2015-12-18)

[EN] The development and optimization of new combustion modes is nowadays an important research field, to reduce the pollutant emissions of the reciprocating internal combustion engines. Their development requires the use ...
Evaluation of the Eulerian-Lagrangian spray atomisation (ELSA) in spray simulations

Hoyas, S; Pastor Enguídanos, José Manuel; Khuong ., Anh Dung; Mompó Laborda, Juan Manuel; Ravet, Frederic (Inderscience, 2011)

[EN] Many approaches have been used to simulate the spray structure especially in modelling fuel sprays, i.e., Eulerian, Lagrangian, Lagrangian- Eulerian, Eulerian-Eulerian and Eulerian-Lagrangian approaches. The present ...
Experimental characterization of direct injection liquid ammonia sprays under non-reacting Diesel-like conditions

Payri, Raul; García-Oliver, José M; Bracho Leon, Gabriela; Cao, Jiawei (Elsevier, 2024-04-15)

[EN] Ammonia is seen as a promising fuel to replace fossil fuels internal combustion engines, given the advantages of zero carbon emission and extensive experience in its synthesis at large scale. The ignition of ammonia ...
High Speed Shadowgraphy of Transparent Nozzles as an Evaluation Tool for In-Nozzle Cavitation Behavior of GDI Injectors

Mamaikin, Dmitrii; Knorsch, Tobias; Rogler, Philipp; Leick, Philippe; Wensing, Michael (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] Gasoline Direct Injection (GDI) systems have become a rapidly developing technology taking up a considerable and rapidly growing share in the Gasoline Engine market due to the thermodynamic advantages of direct ...
Impact of medium-pressure direct injection in a spark-ignition engine fueled by hydrogen

Molina, Santiago; Novella Rosa, Ricardo; Gómez-Soriano, Josep; Olcina-Girona, Miguel (Elsevier, 2024-03-15)

[EN] In the automotive sector, hydrogen is being increasingly explored as an alternative fuel to replace conventional carbon-based fuels. Its combustion characteristics make it well-suited for adaptation to internal ...
Influence of spray-glow plug configuration on cold start combustion for high-speed direct injection diesel engines

Pastor Soriano, José Vicente; Bermúdez, Vicente; García Oliver, José María; Ramírez Hernández, José Gustavo (Elsevier, 2011-09)

Glow plugs are currently the most employed solution to promote ignition in light-duty diesel engines during low temperature cold start. Improved knowledge about the mechanisms that control ignition and flame development ...
