Analysis of Regulated Pollutant Emissions and Aftertreatment Efficiency in a GTDi Engine Using Different SOI Strategies

Bermúdez, Vicente; Luján, José M.; Climent, H.; Soto-Izquierdo, Lian; Campos-Navarro, Daniel (SAE International, 2018)

[EN] In order to improve performance and minimize pollutant emissions in gasoline turbocharged direct-injection (GTDi) engines, different injection strategies and technologies are being investigated. The inclusion of exhaust ...
Assessment of air management strategies on particulate number and size distributions from a 2-stroke compression-ignition engine operating with gasoline Partially Premixed Combustion concept

Bermúdez, Vicente; Ruiz, S.; Novella Rosa, Ricardo; Soto-Izquierdo, Lian (SAGE Publications, 2018)

[EN] The newly designed partially premixed combustion concept has demonstrated its potential to reduce nitrogen oxides and particulate matter emissions combined with highly indicated efficiencies. However, it is highly ...
Assessment on the consequences of injection strategies on combustion process and particle size distributions in Euro VI medium-duty diesel engine

Bermúdez, Vicente; García Martínez, Antonio; Villalta-Lara, David; Soto, Lian (SAGE Publications, 2020-04)

[EN] Although there are already several works where the influence of injection parameters on exhaust emissions, and specifically on particulate matter emissions, in diesel engines has been evaluated, the diversity in the ...
Effect of essential oils on properties of film forming emulsions and films based on HPMC and chitosan

Sánchez González, Laura; Chiralt, A.; González Martínez, María Consuelo; Cháfer Nácher, María Teresa (Elsevier, 2011)

[EN] Film-forming dispersions (FFD) and films, prepared by incorporating different concentrations of bergamot (BO), lemon (LO) and tea tree (TTO) essential oils into hydroxyproplymethylcellulose (HPMC) and chitosan (CH) ...
Effects of multiple injection strategies on gaseous emissions and particle size distribution in a two-stroke compression-ignition engine operating with the gasoline partially premixed combustion concept

Bermúdez, Vicente; Ruiz-Rosales, Santiago; Novella Rosa, Ricardo; Soto-Izquierdo, Lian (SAGE Publications, 2018)

[EN] In order to improve performance of internal combustion engines and meet the requirements of the new pollutant emission regulations, advanced combustion strategies have been investigated. The newly designed partially ...
Impact of injection settings on gaseous emissions and particle size distribution in the dual-mode dual-fuel concept

Bermúdez, Vicente; Macian Martinez, Vicente; Villalta-Lara, David; Soto, Lian (SAGE Publications, 2020-04)

[EN] Reactivity controlled compression ignition concept has been highlighted among the low temperature combustion strategies. However, this combustion strategy presents some problems related to high levels of hydrocarbon ...
Increase of the reactivity of densified silica fume by sonication treatment

Rodríguez Martínez, Erich David; Soriano Martínez, Lourdes; Paya Bernabeu, Jorge Juan; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª (Elsevier, 2012-09)

Five silica fumes from different manufacturers were subjected to ultrasonic treatment in order to decrease particle agglomeration and improve particle dispersion. The effectiveness of the sonication was observed as a ...
Influence of freeze-drying conditions on orange powder flowability

Usganda, Mariana; Silva Espinoza, Marilú Andrea; Egas, Luis; Camacho, María del Mar; Martínez-Navarrete, Nuria (Editorial Universitat Politècnica de València, 2018-09-07)
