1D Modeling of strategies to improve the performance of gasoline, turbocharged, direct injection engines

González Domínguez, David (Universitat Politècnica de València, 2020-12-21)

[ES] Hoy en día, las empresas del sector de la automoción se encuentran en una atmósfera cada vez más competitiva, dado que su actividad está liderada por una combinación de reducción de costes, tecnología más compleja, ...
Coupling methodology of 1D finite difference and 3D finite volume CFD codes based on the Method of Characteristics

Galindo, José; Tiseira, Andrés Omar; Fajardo, Pablo; Navarro, R. (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

[EN] This paper describes the methodology followed to perform a co-simulation between 1D (OpenWAM) and 3D (FLUENT) CFD codes. The Method of Characteristics (MoC) has been chosen to transfer the information between the two ...
Development of an Installation to Emulate Altitude, Ambient Temperature, and Ambient Humidity on Thermal Engines. Application to the Study of the Impact over E6 Engine Performance

Tabet Aleixandre, Roberto (Universitat Politècnica de València, 2022-06-27)

[ES] Las normativas cada vez más restrictivas sobre las emisiones contaminantes de los vehículos de motor impuestas por la Unión Europea han obligado a los fabricantes de equipos originales (OEM) a proporcionar a los centros ...
Dynamic Identification of Thermodynamic Parameters for Turbocharger Compressor Models

Burke, R.D.; Olmeda González, Pablo Cesar; Serrano Cruz, José Ramón (American Society of Mechanical Engineers (ASME), 2015-10)

A novel experimental procedure is presented which allows simultaneous identification of heat and work transfer parameters for turbocharger compressor models. The method introduces a thermally transient condition and uses ...
Experimental and modeling analysis on the optimization of combined VVT and EGR strategies in turbocharged direct-injection gasoline engines with VNT

Galindo, José; Climent, H.; De La Morena, Joaquín; González-Domínguez, David; Guilain, Stephane; Besancon, Thomas (SAGE Publications, 2021-09)

[EN] The combination of a growing number of complex technologies in internal combustion engines (ICE) is commonplace, due to the need of complying with the tight pollutant regulations and achieving high efficiencies. Hence ...
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 ...
Improvement in engine thermal management by changing coolant and oil mass

Broatch, A.; Olmeda, P.; Martín, Jaime; Dreif-Bennany, Amin (Elsevier, 2022-07-25)

[EN] Several investigations related to increasing engine thermal efficiency focusing on the engine hydraulic circuits (oil and coolant) were performed over the last years. According to literature, more than 20% of the fuel ...
Novel Energy Management Control Strategy for Improving Efficiency in Hybrid Powertrains

Broatch, A.; Olmeda, P.; Pla Moreno, Benjamín; Dreif-Bennany, Amin (MDPI AG, 2023-01)

[EN] Energy management in electrified vehicles is critical and directly impacts the global operating efficiency, durability, driveability, and safety of the vehicle powertrain. Given the multitude of components of these ...
