The 4th Workshop of the Engine Combustion Network (ECN) was held September 5-6, 2015
in Kyoto, Japan. This manuscript presents a summary of the progress in experiments and …

Development and mixing of Diesel sprays are long known to be key factors for combustion
and pollutant emissions but the related measurements in a real engine is not an easy task …

Despite the importance of sprays to engine combustion, understanding has been hampered
by the sensitivity of spray behavior to unknown nozzle geometry effects. The Engine …

This study investigates the impact of parametric conditions on the rate of injection (ROI) and
injection quantities of a new piezo-type Engine Combustion Network (ECN) Spray A-3 …

A computational study was performed to investigate the influence of transient needle motion
on gasoline direct injection (GDI) internal nozzle flow and near-field sprays. Simulations …

Transients in the rate of injection (ROI) with respect to time are ever-present in direct-
injection engines, even with common-rail fueling. The shape of the injection ramp-up and …

Fuel physical properties are known to influence in-nozzle flow behavior, in turn affecting
spray formation in internal combustion engines. A series of 3D simulations was performed to …

The internal structure of Diesel fuel injectors is known to have a significant impact on the
nozzle flow and the resulting spray emerging from each hole. In this paper the three …

A state of the art prototype common rail injector featuring direct control of the needle by
means of a piezo stack (direct acting) has been tested. Liquid phase penetration of the …

This work investigates the low-and high-temperature ignition and combustion processes,
applied to the Engine Combustion Network Spray A flame, combining advanced optical …
