Adaptive in-cylinder pressure model for spark ignition engine control

Pla Moreno, Benjamín; De La Morena, Joaquín; Bares-Moreno, Pau; Jimenez, Irina Ayelen (Elsevier, 2021-09-01)

[EN] In-cylinder pressure is the most important variable to analyze the combustion process in internal combustion engines, and can be used as feedback signal for closed-loop combustion control and diagnostics. However, ...
Diseño de una metodología de validación de datos experimentales de una sala de ensayos de un motor de encendido provocado

Subías Ruíz, Alberto (Universitat Politècnica de València, 2021-01-26)

[ES] El proceso de combustión es una parte esencial del ciclo de trabajo de un MCIA. Durante el mismo, debe liberarse la energía química del combustible en un corto periodo de tiempo con el fin de generar el trabajo necesario ...
Effect of passive pre-chamber orifice diameter on the methane combustion process in an optically accessible SI engine

Beltrao de Vargas-Antolini, Jacson; Sementa, Paolo; Tornatore, Cinzia; Catapano, Francesco; Vaglieco, Bianca Maria; Desantes, J.M.; López, J. Javier (Elsevier, 2023-06-01)

[EN] Due to its potential to extend the lean limit or overcome knock-limited conditions on spark-ignited (SI) engines, the pre-chamber spark-ignition (PCSI) concept has gained attention as an efficient alternative to the ...
Estudio de simulación numérica de un motor de combustión interna alimentado con mezclas de combustible de amoníaco e hidrógeno

Sánchez Bayona, Javier (Universitat Politècnica de València, 2023-11-03)

[ES] En las últimas décadas la relevancia de los nuevos combustibles alternativos ha aumentado considerablemente como respuesta a los problemas del calentamiento global y las emisiones contaminantes. La comunidad científica ...
Exploring the potentials of lean-burn hydrogen SI engine compared to methane operation

Sementa, Paolo; Beltrao de Vargas-Antolini, Jacson; Tornatore, Cinzia; Catapano, Francesco; Vaglieco, Bianca Maria; López, J. Javier (Elsevier, 2022-07-12)

[EN] The global rush for decarbonization and the more restrictive emission regulations are pushing the research for cleaner powertrains to the transport sector. In this sense, this work contributes with an experimental ...
Fuel-to-air ratio control under short-circuit conditions through UEGO sensor signal analysis

Guardiola, Carlos; Pla Moreno, Benjamín; Real, Marcelo; TRAVAILLARD, Cyril; Dambricourt, Frederic (SAGE Publications, 2020)

[EN] The impact of short-circuit pulses on the after-treatment system of a spark-ignited engine must be taken into account to keep the fuel-to-air equivalence ratio within the three-way catalyst window, thereby reducing ...
Numerical study on the use of ammonia/hydrogen fuel blends for automotive spark-ignition engines

Novella Rosa, Ricardo; Pastor Enguídanos, José Manuel; Gómez-Soriano, Josep; Sánchez-Bayona, J. (Elsevier, 2023-11-01)

[EN] The importance of new alternative fuels has assumed great relevance in the last decades to face the issues of global warming and pollutant emissions from energy production. The scientific community is responsible for ...
Short-circuit effects on spark ignition engine after-treatment and fuel-to-air ratio control

Guardiola, Carlos; Pla Moreno, Benjamín; Real-Minuesa, Marcelo; Travaillard, Cyril; Dambricourt, Frederic (SAGE Publications, 2020)

[EN] The short circuit of fresh air is a more and more extended strategy to deal with low-end torque issues, very common in small turbocharged and spark-ignited four-stroke engines. Therefore, from the author¿s point of ...
