An on-board method to estimate the light-off temperature of diesel oxidation catalysts

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Mora, Javier (SAGE Publications, 2020-10)

[EN] Current diesel engine regulations include on-board diagnostic requirements so that after-treatment systems need on-board methods to detect their aging state through the available measurements. In a state-of-the-art ...
Development of a Variable Valve Actuation Control to Improve Diesel Oxidation Catalyst Efficiency and Emissions in a Light Duty Diesel Engine

Serrano, J.R.; Arnau Martínez, Francisco José; Martín, Jaime; Auñón-García, Ángel (MDPI AG, 2020-09)

[EN] Growing interest has arisen to adopt Variable Valve Timing (VVT) technology for automotive engines due to the need to fulfill the pollutant emission regulations. Several VVT strategies, such as the exhaust re-opening ...
Diesel engine optimization and exhaust thermal management by means of variable valve train strategies

Arnau Martínez, Francisco José; Martín, Jaime; Pla Moreno, Benjamín; Auñón-García, Ángel (SAGE Publications, 2021-04)

[EN] Due to the need to achieve a fast warm-up of the after-treatment system in order to fulfill the pollutant emission regulations, a growing interest has arisen to adopt variable valve timing technology for automotive ...
Effect of the exhaust thermal insulation on the engine efficiency and the exhaust temperature under transient conditions

Arnau Martínez, Francisco José; Martín, Jaime; Piqueras, P.; Auñón-García, Ángel (SAGE Publications, 2021-09)

[EN] As well as new advances in the after-treatment systems are required to achieve the new pollutant emission requirements, new designs of the exhaust line can be considered in order to increase the engine efficiency and ...
Model-Based Ammonia Slip Observation for SCR Control and Diagnosis

Guardiola, Carlos; Pla Moreno, Benjamín; Bares-Moreno, Pau; Mora, Javier (Institute of Electrical and Electronics Engineers, 2020-06)

[EN] The control of selective catalytic reduction (SCR) systems, via NH3 injection, requires from a precise estimation of the SCR load in order to ensure NOx reduction by minimizing ammonia slip. This article aims to resolve ...
Switching strategy between HP (high pressure)- and LPEGR (low pressure exhaust gas recirculation) systems for reduced fuel consumption and emissions

Lujan Martinez, José Manuel; Guardiola García, Carlos; Plá Moreno, Benjamín; Reig, Alberto (Elsevier, 2015-10)

EGR (Exhaust gas recirculation) plays a major role in current Diesel internal combustion engines as a cost-effective solution to reduce NO emissions. EGR systems will suffer a significant evolution with the introduction ...
