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 in the selected measuring principle. There are no time delays caused by moving components in the measuring system. The latest innovation and further development is operation with hydrogen as the test medium. IAV offers development services in the field of hydrogen injection.
Properties
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: as there are no moving parts, the measuring unit is particularly low-maintenance and the measurement results are exactly reproducible. The device is also insensitive to cold and heat, making it suitable for use 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. It is controlled by powerful software supplied with the unit, which is easy to operate and clearly displays all relevant information.
In addition to real-time display, it is also possible to analyze stored measurement data in detail and replay it (e.g. for presentations). The IAV Cross can also be linked to the user's test bench software via a software interface. This enables integration into your development and testing environment.
