Ammonia injection failure diagnostic and correction in engine after-treatment system by NOx and NH3 emissions observation

Pla Moreno, Benjamín; Bares-Moreno, Pau; Sanchis Pacheco, Enrique José; Nakaema-Aronis, André (Elsevier, 2022-08-15)

[EN] To ensure that after-treatment systems (ATS) reduce emissions to the levels for which they were designed, it is essential that the ATS control can rely on the feedback signals from the sensors and actuators that are ...
Ammonia injection optimization for selective catalytic reduction aftertreatment systems

Pla Moreno, Benjamín; Bares-Moreno, Pau; Sanchis-Pacheco, Enrique José; Nakaema-Aronis, André (SAGE Publications, 2021-07)

[EN] This work presents an optimized ammonia injection strategy for the Worldwide Harmonized Light Vehicles Test Cycle and its potential benefits in terms of NO(x)emissions and ammonia consumption in selective catalytic ...
Ammonia Slip Estimation Based on ASC Control-Oriented Modelling And OBD NOx Sensor Cross-Sensitivity Analysis

Piqueras, P.; Pla Moreno, Benjamín; Sanchis Pacheco, Enrique José; Nakaema-Aronis, André (American Society of Mechanical Engineers (ASME), 2021-10-15)

[EN] The incoming emission regulations for internal combustion engines are gradually introducing new pollutant species, which requires greater complexity of the exhaust gas aftertreatment systems concerning layout, control ...
Application of dynamic optimization and data fusion techniques for SCR control

Nakaema Aronis, André (Universitat Politècnica de València, 2020-12-19)

[ES] Los sistemas de postratamiento SCR son la solución más extendida para la reducción de emisiones de NOx en motores Diesel de automoción, pues permiten reducciones en las emisiones de NOx de hasta el 95%. En los últimos ...
Control and Diagnosis of a SCR-ASC After-Treatment System for NOx and NH3 Emission Reduction Under Real Driving Conditions and Potential System Failure

Nakaema Aronis, André (Universitat Politècnica de València, 2023-03-10)

[ES] Para cumplir los límites de emisiones impuestos por los gobiernos y reducir el impacto negativo en el medio ambiente, el uso de sistemas de postratamiento (ATS) se ha convertido en algo esencial para los motores de ...
Model-based simultaneous diagnosis of ammonia injection failure and catalyst ageing in deNOx engine after-treatment systems

Pla Moreno, Benjamín; Piqueras, P.; Bares-Moreno, Pau; Nakaema-Aronis, André (Elsevier, 2023-07-01)

[EN] After-treatment systems (ATS) in vehicle powertrains are developed to achieve maximum pollutant abatement efficiency under design operating conditions. However, anomalies in the ATS may appear during real operation, ...
NOx sensor cross sensitivity model and simultaneous prediction of NOx and NH3 slip from automotive catalytic converters under real driving conditions

Pla Moreno, Benjamín; Piqueras, P.; Bares-Moreno, Pau; Nakaema-Aronis, André (SAGE Publications, 2021-10)

[EN] This work presents the development of a model to capture the NOx sensors cross sensitivity behavior based on NO(x )sensor cell temperature, as well as a model do predict the slip of the NOx and NH3 after the SCR ...
Simultaneous NOx and NH3 slip prediction in a SCR catalyst under real driving conditions including potential urea injection failures

Pla Moreno, Benjamín; Piqueras, P.; Bares-Moreno, Pau; Nakaema-Aronis, André (SAGE Publications, 2022-07)

[EN] To reach the emission limits imposed by governments and reduce the negative impact on the environment, the use of aftertreatment systems has become essential for internal combustion engine (ICE) based powertrains. In ...
