Analysis and Optimization of the Transient Operation of Gasoline Turbocharged Direct Injection Engines Under High EGR Conditions

González Domínguez, David (Universitat Politècnica de València, 2023-06-05)

[ES] El transporte por carretera es uno de los sectores que más contribuyen al cambio climático. Por ello, muchos gobernantes a nivel mundial están promoviendo una transición hacia medios de transporte sostenibles que no ...
Analysis of heavy-duty turbocharged diesel engine response under cold transient operation with a pre-turbo aftertreatment exhaust manifold configuration

Bermúdez, Vicente; Serrano, J.R.; Piqueras, P.; García Afonso, Óscar (SAGE Publications (UK and US), 2013-08)

Diesel particulate filters are the most useful technology to reduce particulate matter from the exhaust gas of internal combustion engines. Although these devices have suffered an intense development in terms of the ...
Assessment by means of gas dynamic modelling of a pre-turbo diesel particulate filter configuration in a turbocharged HSDI diesel engine under full-load transient operation

Bermúdez, Vicente; Serrano Cruz, José Ramón; Piqueras, P.; García Afonso, Óscar (SAGE Publications, 2011)

Diesel particulate filters (DPF) are becoming a standard technology in diesel engines because of the need for compliance with forthcoming regulations regarding soot emissions. When a great degree of maturity in management ...
Assessment of air management strategies to improve the transient response of advanced gasoline engines operating under high EGR conditions

Galindo, José; Climent, H.; De La Morena, Joaquín; González-Domínguez, David; Guilain, Stéphane (Elsevier, 2023-01-01)

[EN] Advanced gasoline engines may lead the medium-term future of the passenger vehicle market, working in conventional and hybrid powertrains. Downsizing with turbocharging is the most extended way to improve fuel economy ...
Assessment of Variable Geometry Orifice Compressor Technology Impact in a New Generation of Compression Ignition Powertrains at Low-End and Transient Operation

Serrano, J.R.; Climent, H.; Gómez-Vilanova, Alejandro; Darbhamalla, Aditya; Guilain, Stéphane (MDPI AG, 2022-12)

[EN] Surge is a phenomenon that limits the operating range of the compressor at low engine speeds and high boost pressure in turbocharged powertrains. This article assesses two prototype turbochargers of variable geometry ...
Compressor Surge Mitigation in Turbocharged Spark-Ignition Engines without an Anti-Surge Control System during Load-Decrease Operation

Galindo, José; Climent, H.; De La Morena, Joaquín; González-Domínguez, David; Guilain, Stéphane; Besançon, Thomas (MDPI AG, 2022-02)

[EN] Automotive manufacturers are showing an increasing preference for hybrid powertrains based on advanced gasoline engines. The most extended solution to improve fuel economy in these engines consists in downsizing with ...
Experimental assessment of a pre-turbo aftertreatment configuration in a single stage turbocharged diesel engine. Part 2: Transient operation

Lujan Martinez, José Manuel; Serrano Cruz, José Ramón; Piqueras Cabrera, Pedro; García Afonso, Óscar (Elsevier, 2015-02-01)

This paper corresponds to the second part of a work devoted to analyse the impact of the pre-turbo aftertreatment configuration on the performance of a single stage turbocharged Diesel engine. This second part focuses on ...
