Fuel efficiency optimisation based on boosting control of the particulate filter active regeneration at high driving altitude

Piqueras, P.; Burke, Richard; Sanchis Pacheco, Enrique José; Diesel, Bárbara (Elsevier, 2022-07-01)

[EN] The air pressure change as a function of the driving altitude affects negatively the engine performance and emissions as well as the efficiency of the exhaust aftertreatment systems (ATS). These detrimental effects ...
Implementation of two color method to investigate late cycle soot oxidation process in a CI engine under low load conditions

López, J. Javier; Martín, J.; García Martínez, Antonio; Villalta-Lara, David; Warey, Alok (Elsevier, 2017)

[EN] Soot emissions from diesel engines are an important concern in meeting emissions regulations. Soot emissions are the result of two competing processes: soot formation and soot oxidation. Mechanisms of soot formation ...
Investigation of late-cycle soot oxidation using laser extinction and in-cylinder gas sampling at varying inlet oxygen concentrations in diesel engines

Gallo, Yann; Malmborg, Vilhelm B.; Simonsson, Johan; Svensson, Erik; Shen, MengQin; Bengtsson, Per-Erik; Pagels, Joakim; Tuner, Martin; García Martínez, Antonio; Andersson, Öivind (Elsevier, 2017)

[EN] This study focuses on the relative importance of O-2 and OH as oxidizers of soot during the late cycle in diesel engines, where the soot oxidation is characterized in an optically accessible engine using laser extinction ...
