An experimental analysis on the evolution of the transient tip penetration in reacting Diesel sprays

Desantes Fernández, José Mª; Pastor, José V.; García Oliver, José María; Briceño Sánchez, Francisco Javier (Elsevier, 2014-08)

Schlieren imaging has helped deeply characterize the behavior of Diesel spray when injected into an oxygen-free ambient. However, when considering the transient penetration of the reacting spray after autoignition, i.e. ...
Application of optical diagnostics to the quantification of soot in n-alkane flames under diesel conditions

Pastor Soriano, José Vicente; García Oliver, José María; García Martínez, Antonio; Micó Reche, Carlos; Möller, Sebastian (Elsevier, 2016-02)

The present work pursues a twofold objective. On the one hand, the effect of fuel properties on soot formation has been analysed, under different engine operating conditions. On the other hand, sensitivity and performance ...
Effect of multiple injection strategies on the Diesel spray formation and combustion using optical diagnostics

Viera Sotillo, Alberto Antonio (Universitat Politècnica de València, 2019-07-22)

[ES] En los últimos años, la evolución de las tecnologías de inyección ha permitido no solo mejorar el proceso de mezcla, sino también controlar con precisión los parámetros de inyección, agregando flexibilidad a los ...
Ignition and combustion development for high speed direct injection diesel engines under low temperature cold start conditions

Pastor Soriano, José Vicente; García Oliver, José María; Pastor Enguídanos, José Manuel; Ramírez Hernández, José Gustavo (Elsevier, 2011-04)

Diesel engine cold start is an important issue for current technology at low (below 0 °C) temperatures and for future applications. The aim of this work is to develop a description of how, when and where does fuel spray ...
Increased particle emissions from early fuel injection timing Diesel low temperature combustion

Benajes Calvo, Jesus Vicente; García Oliver, José María; Novella Rosa, Ricardo; KOLODZIEJ, CHRISTOPHER PAUL (Elsevier, 2012-04)

A clean premixed Diesel combustion strategy, called low temperature combustion (LTC), was able to achieve very low nitrogen oxide emissions (<35 ppm) through use of exhaust gas recirculation (12.1% inlet oxygen), and reduced ...
Influence of Inter-Jet Spacing on the Diesel Spray Formation and Combustion

Montiel Prieto, Tomás Enrique (Universitat Politècnica de València, 2022-03-25)

[ES] La creciente aversión pública contra los motores de combustión interna ha llevado a un fuerte deseo de cambio hacia fuentes de energía renovables y más limpias. Sin embargo, todavía es difícil reemplazar los combustibles ...
Influence of nozzle geometry on ignition and combustion for high-speed direct injection diesel engines under cold start conditions

Desantes Fernández, José Mª; García Oliver, José María; Pastor Enguídanos, José Manuel; Ramírez Hernández, José Gustavo (Elsevier, 2011-11)

Starting at low temperatures (below 0 °C) is an important issue for current and near future diesel engine technology. Low ambient temperature causes long cranking periods or complete misfiring in small diesel engines and, ...
Investigation of the ignition and combustion processes of a dual-fuel spray under diesel-like conditions using computational fluid dynamics (CFD) modeling

López Sánchez, José Javier; Novella Rosa, Ricardo; García Martínez, Antonio; Winklinger, Johannes Franz (Elsevier, 2011-12)

Recent research activities in the field of diesel engines have shown the potential to reduce pollutant emissions and improve the thermal efficiency by controlling the fuel reactivity. However, understanding the impact ...
Mediciones de longitud de estabilización de llama, retraso del autoencendido y visualización de campo cercano en un inyector de tres orificios de la Engine Combustion Network

Viera Sotillo, Alberto Antonio (Universitat Politècnica de València, 2016-07-22)

[EN] This research is divided into two different set of experimental measurements. First combustion measurements of lift-off length were done via both broadband luminosity and OH chemiluminescence. In addition, ignition ...
Single-cylinder engine evaluation of a multi-component diesel surrogate fuel at a part-load operating condition with conventional combustion

Szymkowicz, Patrick G.; Benajes, Jesús (Elsevier, 2018)

[EN] Simple, yet fully-representative surrogate fuels are needed to model market Diesel fuels. The surrogates must closely mimic market Diesel fuel properties and match the engine combustion and emissions behavior. To this ...
Suitability analysis of advanced diesel combustion concepts for emissions and noise control

Torregrosa, A. J.; Broatch, A.; Novella Rosa, Ricardo; Mónico Muñoz, Luisa Fernanda (Elsevier, 2011-02)

[EN] During the last years, the preservation of the atmospheric environment has played an increasingly important role in society. The Diesel engine can be considered an environmentally friendly engine because of its low ...
The role of detailed chemical kinetics on CFD diesel spray ignition and combustion modelling

Novella Rosa, Ricardo; García Martínez, Antonio; Pastor Enguídanos, José Manuel; Domenech Llopis, Vicente (Elsevier, 2011-10)

Spray ignition and flame stabilisation in the frame of diesel-like combustion conditions combine fundamental and complex physical and chemical processes. In this work, a numerical investigation has been performed to evaluate ...
