A combustion phasing control-oriented model applied to an RCCI engine

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Barbier, Alvin Richard Sebastien (Elsevier, 2018-09-22)

[EN] Low temperature combustions such as Reactivity Controlled Compression Ignition (RCCI) have been shown to be a promising way to reduce pollutants at the exhaust, i.e. NOx and soot emissions, and increase the thermal ...
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 ...
Analysis of Real-Driving Data Variability for Connected Vehicle Diagnostics

Barbier, Alvin Richard Sebastien; Salavert Fernández, José Miguel; Palau Salvador, Carlos Enrique; Guardiola, Carlos (Elsevier, 2022-08-31)

[EN] Connected vehicle paradigm allows the systematic recording of data, which may be made available for both on-board and cloud diagnostics functions. However, real-driving conditions may be highly dynamic, making the ...
Closed-loop control of a dual-fuel engine working with different combustion modes using in-cylinder pressure feedback

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Barbier, Alvin Richard Sebastien (SAGE Publications, 2020-03)

[EN] This work presents a closed-loop combustion control concept using in-cylinder pressure as a feedback in a dual-fuel combustion engine. At low load, reactivity controlled compression ignition combustion was used while ...
Desarrollo de estrategias avanzadas de control de la combustión mediante la medida de la señal de presión en cámara

Barbier, Alvin (Universitat Politècnica de València, 2019-01-16)

La combustión RCCI se basa en el empleo de una mezcla de un combustible de baja reactividad y un combustible de alta reactividad. Debido a la falta de actuación directa sobre el incio de la combustión y a su sensibilidad ...
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 ...
Modeling combustion timing in an RCCI engine bymeans of a control oriented model

Kakoee, A.; Bakhshan, Y.; Barbier, Alvin Richard Sebastien; Bares-Moreno, Pau; Guardiola, Carlos (Elsevier, 2020-04)

[EN] Reactivity controlled compression ignition (RCCI) engines as one of low temperature auto ignition combustion strategies have shown a good performance to reduce NO (x) and soot emission while increasing engine thermal ...
On-Line Optimization of Dual-Fuel Combustion Operation by Extremum Seeking Techniques

Pla Moreno, Benjamín; Bares-Moreno, Pau; Barbier, Alvin Richard Sebastien; Guardiola, Carlos (SAE International, 2021-04-15)

[EN] Dual-fuel combustion engines have shown the potential to extend the operating range of Homogeneous Charge Compression Ignition (HCCI) by using several combustion modes, e.g. Reactivity Controlled Compression Ignition ...
Safe operation of dual-fuel engines using constrained stochastic control

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Barbier, Alvin Richard Sebastien (SAGE Publications, 2022-02)

[EN] Premixed combustion strategies have the potential to achieve high thermal efficiency and to lower the engine-out emissions such as NOx. However, the combustion is initiated at several kernels which create high pressure ...
