Analysis of combustion concepts in a newly designed two-stroke high-speed direct injection compression ignition engine

Benajes Calvo, Jesus Vicente; Novella Rosa, Ricardo; De Lima Moradell, Daniela Andreina; Tribotté, Pascal (SAGE Publications, 2015-01)

[EN] Two research paths are being followed to develop compression ignition engines, the extreme optimization of the conventional diesel combustion concept and the development of alternative combustion concepts. The ...
Analysis of the Internal Thermofluid-Dynamics in a Uniflow Scavenged Engine

Darbhamalla, Aditya (Universitat Politècnica de València, 2024-05-31)

[ES] El transporte terrestre es uno de los principales contribuyentes a las emisiones y tiene un impacto en los cambios climáticos y los peligros para la salud. Para abordar estos problemas, la industria automotriz se está ...
Contribución al modelado unidimensional en motores de dos tiempos de altas prestaciones

Jiménez Macedo, Víctor Daniel (Universitat Politècnica de València, 2013-07-08)

Un modelo de simulación presenta muchas ventajas en el campo del desarrollo de motores de combustión interna alternativos. Su utilidad es doble. Por un lado, para entender la naturaleza de los fenómenos físicos que suceden ...
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 multiple injection strategies on gaseous emissions and particle size distribution in a two-stroke compression-ignition engine operating with the gasoline partially premixed combustion concept

Bermúdez, Vicente; Ruiz-Rosales, Santiago; Novella Rosa, Ricardo; Soto-Izquierdo, Lian (SAGE Publications, 2018)

[EN] In order to improve performance of internal combustion engines and meet the requirements of the new pollutant emission regulations, advanced combustion strategies have been investigated. The newly designed partially ...
Estimation of the in-cylinder residual mass fraction at Intake Valve Closing in a 2-stroke High-Speed Direct-Injection Compression-Ignition engine

Torregrosa, A. J.; Martín, Jaime; Novella Rosa, Ricardo; Thein, Kevin (SAGE Publications, 2020-06)

[EN] New combustion concepts and engine designs are being currently investigated in order to comply with upcoming pollutant regulations and reduce fuel consumption. In this context, two-stroke architectures appear as a ...
Heat transfer modeling in exhaust systems of high-performance two-stroke engines

Lujan Martinez, José Manuel; Climent Puchades, Héctor; Olmeda González, Pablo Cesar; Jiménez Macedo, Víctor Daniel (Elsevier, 2014-08)

Heat transfer from the hot gases to the wall in exhaust systems of high-performance two-stroke engines is underestimated using steady state with fully developed flow empirical correlations. This fact is detected when ...
