The shape of Diesel spray was investigated at real engine conditions in a constant pressure combustion chamber. Schlieren imaging technique was used to make quantitative measurements of spray tip penetration and radial ...
The Engine Combustion Network (ECN) is a worldwide group of institutions using combustion vessels
and/or performing computational fluid dynamics (CFD) simulation, whose aim is to advance the state of
spray and combustion ...
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. This fact led researchers
to simulate ...
In this work, three Engine Combustion Network (ECN) single-hole nozzles with the same nominal characteristics have been tested under a wide range of conditions measuring spray penetration and spreading angle. n-Dodecane ...

The detailed knowledge of the evaporationecombustion process of the Diesel spray is a key factor for the
development of robust injection strategies able to reduce the pollutant emissions and keep or increase
the combustion ...

Fuel direct injection represents one of the key turning points in the development
of the Diesel engines. The appeal of this solution has been growing thanks
to the parallel advancement in the technology of the injection ...
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 sprays in diesel engine-like conditions ...
