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 ...
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 ...
