Adaptive determination of cut-off frequencies for filtering the in-cylinder pressure in diesel engines combustion analysis

Payri González, Francisco; Olmeda González, Pablo Cesar; Guardiola García, Carlos; Martín Díaz, Jaime (Elsevier, 2011-10)

[EN] In-cylinder pressure analysis is a key tool for engine research and diagnosis and it has been object of study from the beginning of the internal combustion engines. One of its most useful application is combustion ...
An analysis of the in-cylinder pressure resonance excitation in internal combustion engines

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Barbier, Alvin Richard Sebastien (Elsevier, 2018)

[EN] This paper analyses the in-cylinder pressure oscillations in internal combustion engines, which are initiated by combustion and resonate during the expansion stroke. A specific mathematical tool, which takes into ...
Cylinder charge composition observation based on in-cylinder pressure measurement

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Stefanopoulou, Anna (Elsevier, 2019-01)

[EN] Accurate cylinder charge and composition estimation is crucial for proper combustion control, however, current sensors and models show different issues for transient estimation. The work presented in this paper combines ...
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 ...
Estimación de la masa atrapada en MCIA mediante el estudio de la resonancia de la presión en cámara

Bares Moreno, Pau (Universitat Politècnica de València, 2015-03-09)

[EN] In-cylinder pressure signal has been largely used for analysing the combustion in reciprocating engines, mainly in test benches, although new engines are being designed with closed loop control based on the in-cylinder ...
In-cylinder pressure based model for exhaust temperature estimation in internal combustion engines

Guardiola, Carlos; Olmeda, P.; Plá Moreno, Benjamín; Bares-Moreno, Pau (Elsevier, 2017)

[EN] Exhaust temperature is a valuable parameter for engine control. However, measurement conditions at the engine exhaust and the slow dynamic response of temperature sensors difficult the determination of the instantaneous ...
In-Cylinder Pressure-Based Control of Premixed Dual-Fuel Combustion

Barbier, Alvin Richard Sebastien (Universitat Politècnica de València, 2022-05-30)

[ES] La actual crisis climática ha instado a la comunidad investigadora y a los fabricantes a brindar soluciones para hacer que el sector del transporte sea más sostenible. De entre las diversas tecnologías propuestas, la ...
Individual cylinder fuel blend estimation in a dual-fuel engine using an in-cylinder pressure based observer

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Barbier, Alvin Richard Sebastien (Elsevier, 2021-04)

[EN] Cylinder-to-cylinder combustion dispersion in internal combustion engines might be caused by various factors (e.g. manufacturing variations of the injectors or nozzle coking) which can result in an increase in pollutant ...
Modelado predictivo de prestaciones y emisiones de un motor diesel de inyección directa basado en la señal de presión en el cilindro

García Sarmiento, Daniel (Universitat Politècnica de València, 2011-07-26)

En la evolución en el control de motor es muy importante el desarrollo de estrategias de control eficientes y robustas, encaminadas a una óptima gestión de los parámetros de entrada en función de mejorar las respuestas del ...
