Abstract
A classification method for an injector may include: actuating the injector by means of a predefinable test control signal, detecting a quantity of liquid dispensed by the injector on the basis of the test control signal, classifying the injector as a function of the detected dispensed quantity of liquid, and determining a required control signal on the basis of the classification of the injector considering a reduced injector stroke. A calibration method for a characteristic map of an injector, and a test bench device for performing the injector classification method are also provided.
Claims14
A classification method for an injector, comprising:
- the injector with a predefinable test control signal,
- a quantity of fluid output by the injector based on the test control signal,
- classifying the injector based on the quantity of fluid output by the injector, and
- determining a necessary control signal based on the classification of the injector taking into account a reduced injector stroke.
A calibration method of a characteristic diagram of an injector, comprising:
- providing a standard characteristic diagram of the injector,
- classifying the injector by a process comprising:
- actuating the injector with a predefinable test control signal,
- detecting a quantity of fluid output by the injector based on the test control signal, and
- classifying the injector based on the quantity of fluid output by the injector, and
- calibrating the standard characteristic diagram of the injector based on the classification.
A test bench device of an injector, comprising:
- a securing device for the injector, and
- an electronic actuation system with which the injector can be actuated with a test control signal,
- wherein the test bench device is configured to classify the injector by:
- actuating the injector with a predefinable test control signal,
- detecting a quantity of fluid output by the injector based on the test control signal,
- classifying the injector based on the quantity of fluid output by the injector, and
- determining a necessary control signal based on the classification of the injector taking into account a reduced injector stroke.
