A new knock event definition for knock detection and control optimization

Bares-Moreno, Pau; Selmanaj, D; Guardiola, Carlos; Onder, C. (Elsevier, 2018)

[EN] In this paper, the knock phenomenon is studied and characterized in the time-frequency domain. From the analysis results, a new knock event definition is proposed, which compares the excitation of the cylinder resonance ...
Acoustic characterization of combustion chambers in reciprocating engines: An application for low knocking cycles recognition

Novella Rosa, Ricardo; Pla Moreno, Benjamín; Bares-Moreno, Pau; Jimenez, Irina Ayelen (SAGE Publications, 2022-01)

[EN] In this paper the acoustic response of a combustion chamber is studied by assuming different pressure field excitation. The viscous effects on the combustion chamber and the finite impedance of the walls have been ...
Influence of a low pressure EGR loop on a gasoline turbocharged direct injection engine

Luján, José M.; Climent, H.; Novella Rosa, Ricardo; Rivas Perea, Manuel Eduardo (Elsevier, 2015-10-05)

his paper presents an experimental study of a low pressure EGR loop on a spark ignition (SI) Gasoline Turbocharged Direct Injection (GTDI) engine that will improve the understanding on the advantages and disadvantages of ...
Knock probability estimation through an in-cylinder temperature model with exogenous noise

Bares-Moreno, Pau; Selmanaj, D; Guardiola, Carlos; Onder, C (Elsevier, 2018)

[EN] This paper presents a new knock model which combines a deterministic knock model based on the in-cylinder temperature and an exogenous noise disturbing this temperature. The autoignition of the end-gas is modelled by ...
Modelling, control and diagnosis of aftertreatment systems based on three-way catalyst in spark-ignited engines

Real Minuesa, Marcelo (Universitat Politècnica de València, 2020-02-17)

[ES] A pesar de la tendencia actual hacia la electrificación del transporte por carretera, los motores de combustión interna alternativos han sido esenciales en este sector y se espera que sigan siendo una tecnología con ...
