Fuel Spray Characterization

The spray pattern, stability and droplet size have a huge impact on the engine’s performance and emissions. LaVision offers a selection of intelligent imaging systems for fuel spray characterization in spray chambers and directly in the engine cylinder.

Spray Applications
  • Diesel and gasoline sprays
  • Multi-hole injectors
  • Spray pattern, spray angle and penetration
  • Temporal evolution of spray cones with high-speed imaging
  • Wall wetting
  • Evaporation, gas-liquid-phase separation
LaVision provides solutions for different stages of spray development
