Database of experimental results on optical diesel sprays characterisation w/o evaporation

A complete database of macroscopic and microscopic spray characteristics of Diesel fuel injection systems has been provided to the partners inside the project.

Different nozzle geometries for small diesel engines have been used. Different orifice shapes, cylindrical, convergent and divergent nozzles. Two types of orifice seats were presented as well: Valve covered orifice and microsac seat.

As expected, the VCO nozzle presents higher hole-to-hole dispersion than the equivalent microsac nozzle. In any case double-guided bosch nozzle present a substantial reduction in hole to hole spray dispersion than previous generation of injectors.

Convergent orifices provide a higher penetration due to the higher exit velocity.
