The Injetvision jet visualization system

The vision chamber    Injetvision benchOffset injector holder    Spray analyzer interface

The state-of-the-art Injetvision system is designed to enable visualization of high-pressure diesel injector jets in an inert atmosphere, thus accurately reproducing combustion conditions in a motor. With a high-speed camera capturing an image every 100µs the system will give you exhaustive morphological information about injector behaviour. What's more, the dedicated Injetvision software Spray Analyzer will enable you to predict the shot-to-shot repeatability of the injector as well as providing vital statistical information.                 For an overview of Injetvision...

The vision chamber

  • Standards-compliant steel cavity with up to 4 reinforced visualization portholes capable of withstanding pressure of up to 50 bars

  • Complete pressure control system driving gas back pressure

  • Fog extraction system cleans the chamber automatically after each injection, guaranteeing neutral conditions

  • High-quality semi-conductor lighting ensuring extremely detailed images

  • Image acquisition by an intensified camera - instantaneous imaging minimum exposure time 200ns

  • Different injector holders to reproduce the injector position inside the cylinder head
