A study on the relationship between internal nozzle geometry and injected mass distribution of eight ECN Spray G nozzles

Matusik, Katarzyna; Duke, Daniel; Sovis, Nicholas; Swantek, Andrew; Powell, Christopher; Payri, Raul; Vaquerizo, Daniel; Giraldo Valderrama, Jhoan Sebastián; Kastengren, Alan (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] Gasoline direct injection (GDI) nozzles are manufactured to meet geometric specifications with length scales on the order of a few hundred microns. The machining tolerances of these nominal dimensions are not always ...
Analysis of the interaction of Spray G and in-cylinder flow in two optical engines for late gasoline direct injection

Geschwindner, Christopher; Kranz, Patrick; Welch, Cooper; Schmidt, Marius; Bohm, Benjamin; Kaiser, Sebastian A.; De La Morena, Joaquín (SAGE Publications, 2020-01)

[EN] An investigation of the interaction between the in-cylinder flow and the spray topology in two spray-guided direct injection optical engines is reported. The bulk flow field in the combustion chamber is characterized ...
Atomización y mezcla en toberas de inyección directa de gasolina (GDi) en condiciones realistas de motor

Bermejo López, Laura (Universitat Politècnica de València, 2020-10-29)

[ES] Los sistemas de inyección directa de gasolina (GDi) están cobrando especial relevancia desde hace unos años en el campo de la automoción con motor de combustión interna alternativos. La optimización de estos sistemas ...
ECN Spray G External Spray Visualization and Spray Collapse Description through Penetration and Morphology Analysis

Payri, Raul; Salvador, Francisco Javier; Marti-Aldaravi, Pedro; Vaquerizo, Daniel (Elsevier, 2017-02-05)

[EN] Inside a DISI engine, a wide range of pressure and temperature conditions are possible, and with the current evolution of the systems, many of the conditions are subject to be encountered at the moment of injection. ...
Internal and near nozzle measurements of Engine Combustion Network "Spray G" gasoline direct injectors

Duke, Daniel J.; Kastengren, Alan L.; Matusik, Katarzyna E.; Swantek, Andrew B.; Powell, Christopher F.; Payri, Raul; Vaquerizo, Daniel; Itani, Lama; Bruneaux, Gilles; Grover Jr., Ronald O.; Parrish, Scott; Markle, Lee; Schmidt, D.; Manin, Julien; Skeen, Scott A.; Pickett, L.M. (Elsevier, 2017-11)

[EN] Gasoline direct injection (GDI) sprays are complex multiphase flows. When compared to multi-hole diesel sprays, the plumes are closely spaced, and the sprays are more likely to interact. The effects of multi-jet ...
Numerical Analysis of GDI Flash Boiling Sprays Using Different Fuels

Payri, Raul; Marti-Aldaravi, Pedro; Abboud, Rami; Bautista-Rodríguez, Abián (MDPI AG, 2021-09)

[EN] Modeling the fuel injection process in modern gasoline direct injection engines plays a principal role in characterizing the in-cylinder mixture formation and subsequent combustion process. Flash boiling, which usually ...
