Analysis of Altitude and Ambient Temperature Effects on the Reactivity of Oxidation Catalysts in the Presence of H2

Serrano, J.R.; Piqueras, P.; Sanchis, Enrique José; Conde-Cortabitarte, Carla (MDPI AG, 2024-06)

[EN] Worldwide emission standards are now required to cover engine operation under extreme ambient conditions, which affect the raw emissions and the efficiency of the exhaust aftertreatment systems. These regulations also ...
Caracterización y mejora genética de la termotolerancia de levaduras del género Saccharomyces procedentes de diversos nichos ecológicos

Cerda García-Caro, Roberto de la (Universitat Politècnica de València, 2018-03-02)

[ES] Las levaduras son unos de los microrganismos más versátiles, ampliamente utilizados en diversos procesos biotecnológicos. Esto es debido a sus características metabólicas, como la producción de etanol y la tolerancia ...
Estudio de emisiones gaseosas y prestaciones en el modo de combustión RCCI mediante el uso de gasolina/diésel aplicado en un motor medium-duty de combustión interna

Boronat Colomer, Vicente (Universitat Politècnica de València, 2017-08-28)

Reactivity controlled compression ignition (RCCI) concept offers ultra-low NOx and smoke emissions with a thermal efficiency. The present work investigates the capabilities of this new Low Temperature Combustion (LTC) ...
Fuel temperature influence on the performance of a last generation common-rail diesel ballistic injector. Part I: Experimental mass flow rate measurements and discussion

Salvador Rubio, Francisco Javier; Gimeno, Jaime; Carreres Talens, Marcos; Crialesi Esposito, Marco (Elsevier, 2016-04-15)

An experimental study is conducted in this paper in order to assess the influence of the fuel temperature on the performance of a last generation common-rail ballistic solenoid injector. Mass flow rate measurements are ...
Influence of spray-glow plug configuration on cold start combustion for high-speed direct injection diesel engines

Pastor Soriano, José Vicente; Bermúdez, Vicente; García Oliver, José María; Ramírez Hernández, José Gustavo (Elsevier, 2011-09)

Glow plugs are currently the most employed solution to promote ignition in light-duty diesel engines during low temperature cold start. Improved knowledge about the mechanisms that control ignition and flame development ...
Potential of exhaust heat recovery for intake charge heating in a Diesel engine transient operation at cold conditions

Lujan Martinez, José Manuel; Climent Puchades, Héctor; Dolz Ruiz, Vicente; Moratal Martínez, Ausiás Alberto; Borges Alejo, José; Soukeur, Zoulikha (Elsevier, 2016-07-25)

In this paper, an experimental facility is implemented with the aim of improving the performance of internal combustion engines working at low ambient temperatures. Pollutant emissions and fuel consumption are one of the ...
Synthesis of high surface area TiO2 nanoparticles by mild acid treatment with HCl or HI for photocatalytic propene oxidation

Ouzzine, M.; Maciá Agulló, Juan Antonio; Lillo-Ródenas, M. A.; Quijada Tomás, Cesar; Linares-Solano, A. (Elsevier, 2014-07)

Nanostructured TiO2 photocatalysts with small crystalline sizes have been synthesized by sol-gel using the amphiphilic triblock copolymer Pluronic P123 as template. A new synthesis route, based on the treatment of TiO2 ...
Ultrasound assisted low temperature drying of food materials

Sabarez, H. T.; Keuhbauch, S.; Knoerzer, K. (Editorial Universitat Politècnica de València, 2018-09-07)

[EN] An ultrasonic design based on the indirect transmission of ultrasonic energy from the ultrasound emitter through to the material to be dried was investigated to assist in low temperature drying of food materials. The ...
