Adaptation of a 1-D tool to study transient thermal in turbocharger bearing housing

Serrano, J.R.; Tiseira, Andrés-Omar; García-Cuevas González, Luis Miguel; Rodriguez-Usaquen, Yuly Tatiana (Elsevier, 2018)

[EN] The heat transfer model can be used in a one-dimensional (1-D) engine simulation. When the engine speed is reduced to zero, the codes have been upgraded to calculate transient turbocharger thermal conditions. The ...
Detection of local oxygen depletion in proton-exchange membrane fuel cells by means of a reduced-order model.

Lalangui Gallegos, José Andrés (Universitat Politècnica de València, 2024-10-16)

[ES] Hoy en día, el incremento de regulaciones que restringen el uso de sistemas propulsivos basados en motores de combustión interna, debido al problema de producción de gases contaminantes, ha dado impulso al desarrollo ...
Development of a Variable Valve Actuation Control to Improve Diesel Oxidation Catalyst Efficiency and Emissions in a Light Duty Diesel Engine

Serrano, J.R.; Arnau Martínez, Francisco José; Martín, Jaime; Auñón-García, Ángel (MDPI AG, 2020-09)

[EN] Growing interest has arisen to adopt Variable Valve Timing (VVT) technology for automotive engines due to the need to fulfill the pollutant emission regulations. Several VVT strategies, such as the exhaust re-opening ...
Diesel engine optimization and exhaust thermal management by means of variable valve train strategies

Arnau Martínez, Francisco José; Martín, Jaime; Pla Moreno, Benjamín; Auñón-García, Ángel (SAGE Publications, 2021-04)

[EN] Due to the need to achieve a fast warm-up of the after-treatment system in order to fulfill the pollutant emission regulations, a growing interest has arisen to adopt variable valve timing technology for automotive ...
Effect of the exhaust thermal insulation on the engine efficiency and the exhaust temperature under transient conditions

Arnau Martínez, Francisco José; Martín, Jaime; Piqueras, P.; Auñón-García, Ángel (SAGE Publications, 2021-09)

[EN] As well as new advances in the after-treatment systems are required to achieve the new pollutant emission requirements, new designs of the exhaust line can be considered in order to increase the engine efficiency and ...
Experimental validation of a one-dimensional twin-entry radial turbine model under non-linear pulse conditions

Serrano, J.R.; Arnau Martínez, Francisco José; García-Cuevas González, Luis Miguel; Soler-Blanco, Pablo; Cheung, Raymond (SAGE Publications, 2021-02)

[EN] This article presents the experimental validation of a complete integrated one-dimensional twin-scroll turbine model able to be used in reciprocating internal combustion engine unsteady simulations. A passenger car ...
One-dimensional modeling of the interaction between close-coupled injection events for a ballistic solenoid injector

Payri, Raul; De La Morena, Joaquín; Pagano, Vincenzo; Hussain, Ali; Sammut, Gilbert; Smith, Les (SAGE Publications, 2019-04)

[EN] In this article, an investigation of a solenoid common-rail injector has been carried out to understand the hydraulic interactions between close-coupled injection events. For this purpose, a one-dimensional model of ...
Radial turbine sound and noise characterisation with acoustic transfer matrices by means of fast one-dimensional models

Torregrosa, A. J.; García-Cuevas González, Luis Miguel; Inhestern, Lukas Benjamin; Soler-Blanco, Pablo (SAGE Publications, 2021-04-01)

[EN] Estimating correctly the turbine acoustics can be valuable during the engine design stage; in fact, it can lead to a more optimised design of the silencer and aftertreatment, as well as to better prediction of the ...
Simulation and modelling of the performance of radial turbochargers under unsteady flow

Soler Blanco, Pablo (Universitat Politècnica de València, 2020-04-27)

[ES] Está fuera de toda duda que la industria del automóvil está viviendo una profunda transformación que, durante los últimos años, ha progresado a un ritmo acelerado. Debido a la crecientemente estricta regulación sobre ...
Synthesis of the 1D modelling of turbochargers and its effects on engine performance prediction

Dombrovsky, Artem (Universitat Politècnica de València, 2017-06-05)

Low fuel consumption is one of the main requirement for current internal combustion engines for passenger car applications. One of the most used strategies to achieve this goal is to use downsized engines (smaller engines ...
Turbocharger heat transfer and mechanical losses influence in predicting engines performance by using one-dimensional simulation codes

Serrano Cruz, José Ramón; Olmeda González, Pablo Cesar; Arnau Martínez, Francisco José; Dombrovsky, Artem; Smith, Les (Elsevier, 2015-06-15)

The exhaust energy can represent up to 40% of the fuel chemical energy in turbocharged internal combustion engines. In order to calculate properly the available energy of the exhaust gases, a critical parameter is the ...
