Advantages of using a cooler bypass in the low-pressure exhaust gas recirculation line of a compression ignition diesel engine operating at cold conditions

Galindo, José; Dolz, Vicente; Monsalve-Serrano, Javier; Bernal-Maldonado, Miguel Angel; Odillard, Laurent (SAGE Publications, 2021-05)

[EN] The low efficiency of the after-treatment systems during the cold start period of the internal combustion engines leads to excessive pollutant emissions levels. To reduce the nitrogen oxide emissions at these conditions, ...
EGR cylinder deactivation strategy to accelerate the warm-up and restart processes in a Diesel engine operating at cold conditions

Galindo, José; Dolz, Vicente; Monsalve-Serrano, Javier; Bernal-Maldonado, Miguel Angel; Odillard, Laurent (SAGE Publications, 2022-04)

[EN] The aftertreatment systems used in internal combustion engines need high temperatures for reaching its maximum efficiency. By this reason, during the engine cold start period or engine restart operation, excessive ...
High-pressure exhaust gas recirculation line condensation model of an internal combustion diesel engine operating at cold conditions

Luján, José M.; Dolz, Vicente; Monsalve-Serrano, Javier; Bernal-Maldonado, Miguel Angel (SAGE Publications, 2021-02)

[EN] To fulfill the future NOx emission regulations, the use of exhaust gas recirculation could be necessary for the engine starting at cold conditions. In this context, condensation inside the exhaust gas recirculation ...
Impacts of the exhaust gas recirculation (EGR) combined with the regeneration mode in a compression ignition diesel engine operating at cold conditions

Galindo, José; Dolz, Vicente; Monsalve-Serrano, Javier; Bernal-Maldonado, Miguel Angel; Odillard, Laurent (SAGE Publications, 2021-12)

[EN] Internal combustion engines working at cold conditions lead to the production of excessive pollutant emissions levels. The use of the exhaust gas recirculation could be necessary to reduce the nitrogen oxides emissions, ...
Influence of ambient temperature on diesel engine raw pollutants and fuel consumption in different driving cycles

Luján, José M.; Climent, H.; Ruiz-Rosales, Santiago; Moratal, Ausias (SAGE Publications, 2019-10)

[EN] The effect of low ambient temperature on diesel raw pollutant emissions is analysed in two different driving cycles: NEDC and WLTC. The study is focused on hydrocarbons, carbon monoxide, nitrogen oxides and fuel ...
Pollutant emissions and diesel oxidation catalyst performance at low ambient temperatures in transient load conditions

Luján, José M.; Climent, H.; García-Cuevas González, Luis Miguel; Moratal-Martínez, Ausias Alberto (Elsevier, 2018-01)

[EN] In this paper an experimental analysis of the ambient temperature effect on diesel engine pollutant emissions is carried out. The study is focused on hydrocarbons and carbon monoxide of both engine out pollutants ...
