The system calculates the injection rate via the dynamic pressure increase in a fuel-filled measuring channel into which the nozzle injects directly. The IAV Cross thus differs from comparable devices by the chosen measuring principle. Time delays caused by moving components in the measuring system are eliminated. The latest innovation and advancement is the use of hydrogen and methanol as a test medium.
Main Components
The biggest advantage of the IAV Cross is the ability to measure both injection rates and injection quantities simultaneously as individual events and to display the rate signal with maximum precision. Another advantage: since there are no moving parts, the measuring unit requires very little maintenance and the measuring results are exactly reproducible. In addition, the unit is insensitive to cold and heat, which means it can also be used in temperature chambers.
In addition to the hydraulic unit, the IAV Cross includes a separate electronic unit that records and processes the data and conditions the measuring technology. The unit is controlled via a powerful software package that is supplied with the unit and is characterised by user-friendly operation and clear display of all relevant information.
In addition to real-time display, it is also possible to analyse stored measurement data in detail and replay it (for presentations, for example). IAV Cross can also be linked to the user’s test stand software via a software interface. Integration into your development and testing environment is thus possible.
