Análisis en banco motor de la eficiencia de conversión de un TWC empleando GLP y AutoGas como combustibles

Castro Espín, Mar (Universitat Politècnica de València, 2022-10-05)

[ES] Entre los grandes cambios que está viviendo el sector del transporte se encuentra el uso de combustibles de baja emisión de CO2, como el GLP con distintas proporciones de propano y butano. Dentro de este ensayo, este ...
Assessment of exhaust raw emissions and aftertreatment performance in a retrofitted heavy duty-spark ignition engine operating with liquefied petroleum gas

Bermúdez, Vicente; Ruiz-Rosales, Santiago; Sanchis, Enrique José; Conde-Pabón, Brayan Yessid (Elsevier, 2024-01-01)

[EN] This study investigates the effects of varying Liquefied Petroleum Gas compositions on pollutant emissions and three-way catalyst performance in retrofitted heavy-duty spark-ignition engines. It focuses on fuels with ...
Control-oriented modelling of three-way catalytic converter for fuel-to-air ratio regulation in spark ignited engines

Guardiola, Carlos; Climent, H.; Pla Moreno, Benjamín; Real, Marcelo (SAGE Publications, 2019-12)

[EN] The purpose of this paper is to introduce a grey-box model of three-way catalytic converter, which is capable of estimating the oxygen storage level to aid the fuel-to-air ratio control in spark ignited engines. As ...
Fuel-to-air ratio control under short-circuit conditions through UEGO sensor signal analysis

Guardiola, Carlos; Pla Moreno, Benjamín; Real, Marcelo; TRAVAILLARD, Cyril; Dambricourt, Frederic (SAGE Publications, 2020)

[EN] The impact of short-circuit pulses on the after-treatment system of a spark-ignited engine must be taken into account to keep the fuel-to-air equivalence ratio within the three-way catalyst window, thereby reducing ...
Modelling three-way catalytic converter oriented to engine cold-start conditions

Real, Marcelo; Hedinger, Raffael; Pla Moreno, Benjamín; Onder, Christopher (SAGE Publications, 2021-02)

[EN] This article introduces a physical model of a three-way catalytic converter oriented to engine cold-start conditions. Computational cost is an important factor, particularly when the modelling is oriented to the ...
Short-circuit effects on spark ignition engine after-treatment and fuel-to-air ratio control

Guardiola, Carlos; Pla Moreno, Benjamín; Real-Minuesa, Marcelo; Travaillard, Cyril; Dambricourt, Frederic (SAGE Publications, 2020)

[EN] The short circuit of fresh air is a more and more extended strategy to deal with low-end torque issues, very common in small turbocharged and spark-ignited four-stroke engines. Therefore, from the author¿s point of ...
