fuel injection technology Dry Calibration and Test GDI Injector

The Dry Calibration and Test GDI Injector bench  for low pressure gasoline injectors in dry condition.
The obtained data and results are used for high-volume production process development.
In order to obtain detailed data sets, several measurement systems are combined with rapid data acquisition. The recorded parameters and results are evaluated using the data analysis tool MATLAB.
The separation of data recording and analysis in the  “Dry Calibration“ of Gasoline Injectors Test Bench allows post processing of data with different settings and algorithms at any time.
