Method, computer program and device for measuring the injection quantity of injection nozzles,especially for motor vehicles

摘要

In a method for measuring the injection quantity of injection systems (32, 33), in particular for motor vehicles and in particular in production testing, an injection system (32, 33) injects a testing fluid into a measuring chamber (45). A detection device (68) detects a movement of a piston (40), which at least partially defines the measuring chamber (45). This detection device (68) generates a corresponding measurement signal (sm). In order to increase the precision of the calculation of the injected testing fluid mass, the invention proposes that the pressure (p) of the testing fluid in the measuring chamber (45) be detected and that the measurement signal (sm) be processed (80) taking into account the detected pressure (p).
