INJECTION SPRAY VISUALIZATION

INJETVISION: injection spray visualization

The INJETVISION spray visualization system is ideal for automatically studying the evolution of single or multi-jet gasoline or diesel injector jets during injection.

The purpose of the INJETVISION vision system is to observe and study the jets from high-pressure gasoline or diesel injectors in an inert atmosphere (nitrogen or CO2) at up to 50 bar relative pressure (± 0.5 bar).

It is equipped with high-performance software for the complete image processing chain, from image acquisition to image processing.

SprayAcq software

This software is used to automate a complete sequence of jet image acquisitions. It can acquire Alpha and Lambda images of injection jets. It manages the entire INJETVISION system. It manages the entire INJETVISION system. In summary, it controls

• the injector control pulse,
• the pressure in the vision chamber,
• the pressure in the rail,
• the position of the jet deflector,
• injector rotation,
• the two cameras for bottom and side views of the jets.

SprayAnalyser softwarer

This software enables the morphological parameters of gasoline or diesel injector jets to be studied automatically. It complements the SprayAcq image acquisition software.

• Jet penetration
• Jet penetration percentage
• Jet opening angle
• Surface area and volume of a jet
• Symmetry
• Sheet angle of a jet in Lambda view
• Lambda angle of a jet in Lambda view
• Alpha angle of a jet
• Inter-jet angle
• Circularity

The entire image processing chain is thus mastered, from acquisition to image processing and the formatting of results.
