A complete 0D thermodynamic predictive model for direct injection diesel engines

Payri González, Francisco; Olmeda, P.; Martín Díaz, Jaime; García Martínez, Antonio (Elsevier, 2011-06-01)

[EN] Ideal models provide the simplest way to reproduce internal combustion engine (ICE) cycles, but they usually do not represent with sufficient accuracy the actual behaviour of an ICE. A suitable alternative for research ...
A fluid dynamic model for unsteady compressible flow in wall-flow diesel particulate filters

Torregrosa Huguet, Antonio José; Serrano Cruz, José Ramón; Arnau Martínez, Francisco José; Piqueras Cabrera, Pedro (Elsevier, 2011-01)

The use of particulate filters (DPF) in Diesel engines has become in recent years the standard technology for the control of soot aerosol emissions. Once emissions reduction through the management of filtration and ...
Analysis of Regulated Pollutant Emissions and Aftertreatment Efficiency in a GTDi Engine Using Different SOI Strategies

Bermúdez, Vicente; Luján, José M.; Climent, H.; Soto-Izquierdo, Lian; Campos-Navarro, Daniel (SAE International, 2018)

[EN] In order to improve performance and minimize pollutant emissions in gasoline turbocharged direct-injection (GTDi) engines, different injection strategies and technologies are being investigated. The inclusion of exhaust ...
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 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 ...
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 ...
Development of a control-oriented model to optimise fuel consumption and NOX emissions in a DI Diesel engine

Molina, Santiago; Guardiola, Carlos; Martín Díaz, Jaime; García Sarmiento, Daniel (Elsevier, 2014-04-15)

This paper describes a predictive NOX and consumption model, which is oriented to control and optimisation of DI Diesel engines. The model applies the Response Surface Methodology following a two-step process: firstly, the ...
Experimental theoretical methodology for determination of inertial pressure drop distribution and pore structure properties in wall-flow diesel particulate filters (DPFs)

Payri González, Francisco; Broatch Jacobi, Jaime Alberto; Serrano Cruz, José Ramón; Piqueras Cabrera, Pedro (Elsevier, 2011-12)

Wall-flow particulate filters have been placed as a standard technology for Diesel engines because of the increasing restrictions to soot emissions. The inclusion of this system within the exhaust line requires the development ...
Potential of using a nozzle at the compressor inlet of a high-speed direct-injection diesel engine

Desantes, J.M.; Luján, José M.; Plá Moreno, Benjamín; Soler Muniesa, José Antonio (SAGE Publications, 2011)

[EN] The present work reports the effect of a nozzle placed upstream of the compressor of a high-speed direct-injection diesel engine. It has been observed that mounting a nozzle at the compressor inlet can lead to a shift ...
