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 ...
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 ...
