Abstract
The invention relates to a method for determining the injection rate of an injection valve () using a mathematical model which is based on measurement values comprising the stroke (x) of a piston () that delimits a measurement chamber () during the injection of a test fluid () into the measurement chamber (). The injection rate is corrected on the basis of an additional measurement value. According to the invention, the pressure (p) in an adapter volume (), via which the injection valve () is connected to the measurement chamber (), is used as an additional measurement value for correcting the injection rate. The invention further relates to a device for determining the injection rate of an injection valve.
