METHOD, COMPUTER PROGRAM AND DEVICE FOR MEASURING THE INJECTION QUANTITY OF INJECTION NOZZLES, ESPECIALLY FOR MOTOR VEHICLES

摘要

The invention relates to a method for measuring the injection quantity of injection systems (32, 33), especially for motor vehicles and particularly for in-process inspection, wherein a test fluid is injected into a measuring chamber (45) by an injection system (32, 33). The movement of a piston (40) limiting at least certain areas of the measuring chamber (45) is detected by a sensing device (68) that supplies a corresponding measuring signal. In order to achieve enhanced accuracy in calculating the injected test liquid quantity, the test fluid pressure (p) is detected in the measuring chamber (45) and the measuring signal is processed (80) taking into account the detected pressure (p).
