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 ...
Adaptive determination of cut-off frequencies for filtering the in-cylinder pressure in diesel engines combustion analysis

Payri González, Francisco; Olmeda González, Pablo Cesar; Guardiola García, Carlos; Martín Díaz, Jaime (Elsevier, 2011-10)

[EN] In-cylinder pressure analysis is a key tool for engine research and diagnosis and it has been object of study from the beginning of the internal combustion engines. One of its most useful application is combustion ...
Correlations for Wiebe function parameters for combustion simulation in two-stroke small engines

Galindo Lucas, José; Climent Puchades, Héctor; Plá Moreno, Benjamín; Jiménez Macedo, Víctor Daniel (Elsevier, 2011-05)

Combustion simulation in two-stroke engines becomes necessary not only for engine performance prediction but also for scavenge evaluation, since in-cylinder pressure and temperature are highly influenced by combustion ...
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 ...
Experiments on the influence of intake conditions on local instantaneous heat flux in reciprocating internal combustion engines

Desantes, J.M.; Torregrosa, A. J.; Broatch, A.; Olmeda González, Pablo Cesar (Elsevier, 2011-01)

[EN] The present study tries to be a contribution for the development of more precise theoretical models for predicting the dissipation of heat through the combustion chamber walls of reciprocating (internal combustion) ...
Impact of Spark Assistance and Multiple Injections on Gasoline PPC Light Load

Benajes Calvo, Jesus Vicente; Tormos Martínez, Bernardo Vicente; García Martínez, Antonio; Monsalve Serrano, Javier (SAE International, 2014-10)

Along the last years, engine researchers are more and more focusing their efforts on the advanced low temperature combustion (LTC) concepts with the aim of achieving the stringent limits of the current emission legislations. ...
Investigation on Multiple Injection Strategies for Gasoline PPC Operation in a Newly Designed 2-Stroke HSDI Compression Ignition Engine

Benajes Calvo, Jesus Vicente; Novella Rosa, Ricardo; De Lima Moradell, Daniela Andreina; Tribotte, Pascal (SAE International, 2015-04)

Partially Premixed Combustion (PPC) of fuels in the gasoline octane range has proven its potential to achieve simultaneous reduction in soot and NOX emissions, combined with high indicated efficiencies; while still retaining ...
The role of in-cylinder gas density and oxygen concentration on late spray mixing and soot oxidation processes

Benajes Calvo, Jesus Vicente; Novella Rosa, Ricardo; García Martínez, Antonio; Arthozoul ., Simon Jean Louis (Elsevier, 2011)

An analysis of in-cylinder gas density and oxygen mass concentration (YO 2) impact on the mixing and oxidation processes and the final soot emissions in conventional high temperature diffusive Diesel combustion conditions ...
