Device for determining injection quantity and/or injection rate of e.g. fuel injected into engine, has evaluation unit to determine injection quantity and/or injection rate depending on picked-up beam image of liquid and sensed condition

摘要

The device comprises a measurement chamber (1), an interface for receiving the injection valve (4), a sensor (6) for measuring the prevailing state of the measurement chamber, and an evaluating unit for determining the injection quantity and/or the injection rate of liquid, depending on the sensed condition. A beam imaging device is arranged for imaging the sprayed liquid. The evaluation unit determines the injection quantity and/or injection rate, depending on the picked-up beam image (5a) of the injected liquid and the sensed condition. An independent claim is included for method for determining injection quantity and/or injection rate of liquid injected through valve.
