A Comprehensive Modeling Toolchain for Particle Emissions in GDI Engines

Abboud, Rami (Universitat Politècnica de València, 2024-09-02)

[ES] La formación de hollín en los motores de inyección directa de gasolina se rige por complejas interacciones entre procesos físicos, que varían en función del modo de funcionamiento del motor. Con la aplicación de ...
Analysis of spray/wall impingement using an ECN single-hole injector and a controlled-temperature wall under realistic engine conditions

Peraza, Jesús E; Payri, Raul; Gimeno, Jaime; Carvallo-Garcia, Cesar (Elsevier, 2022-05-25)

[EN] Spray¿wall interactions (SWI) directly affect fuel¿air mixture and emissions formation. Therefore, they are considered among the most critical physical processes in engine research nowadays. However, the physics of ...
ECN Spray D visualization of the spray interaction with a transparent wall under engine-like conditions, Part II: Impinging spray combustion

Peraza, Jesús E; Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro (Elsevier, 2022-01-15)

[EN] In spite of the ever more comprehensive studies on diesel combustion, there is still an important gap on the fundamental knowledge about the interaction of fuel sprays with the piston and cylinder walls in internal ...
ECN Spray D visualization of the spray interaction with a transparent wall under engine-like conditions. Part I: Non-reactive impinging spray

Peraza, Jesús E.; Salvador, Francisco Javier; Gimeno, Jaime; Ruiz-Rosales, Santiago (Elsevier, 2022-01-01)

[EN] The possibility for a jet of fuel to collide against the surfaces of the combustion chamber or the piston bowl into a thermal engine, has a direct effect on the droplets breakup and the spray atomization. In order to ...
Engine Combustion Network "Spray G": Wall heat transfer characterization by infrared thermography

Zaccara, Mirko; Carvallo-García, César Leonardo; Montanaro, Alessandro; Gimeno, Jaime; Allocca, Luigi; Cardone, Gennaro (Elsevier, 2022-12)

[EN] Nowadays, several efforts are being made to design more efficient, cleaner, and economically accessible engines. Spray-wall interactions are strongly related with the fuel-air mixture and emission formation. As such, ...
Experimental study of the behavior of gasoline direct injection GDI sprays during wall impingement under realistic engine conditions.

Carvallo García, César Leonardo (Universitat Politècnica de València, 2023-07-17)

[ES] A medida que aumenta la conciencia climática y se buscan reducir las emisiones globales, se están realizando esfuerzos para producir tecnologías que permitan desarrollar motores más limpios y amigables con el medio ...
Experimental study of the diesel spray behavior during the jet-wall interaction at high pressure and high temperature conditions

Peraza Ávila, Jesús Enrique (Universitat Politècnica de València, 2020-09-02)

[EN] The potential of diesel engines in terms of robustness, efficiency and energy density has made them widely used as power generators and propulsion systems. Specifically, fuel atomization, vaporization and air-fuel ...
