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).

摘要： The invention relates to a device (10) for measuring the injected-fuel quantity of injection systems (32), in particular for internal combustion engines and in particular in an in-process inspection, comprising a measuring chamber (45). The invention is also provided with a connection device (28), which allows at least one injection system (32) to be connected to the measuring chamber (45) in a pressure-tight manner. A piston (40) is guided through a wall of the measuring chamber (45). The invention also relates to a registration device (58), which registers a displacement of the piston (40). To increase the measuring precision of the device (10), the registration device (58) operates in a contactless manner.

摘要： The invention relates to a method for measuring the injection quantity of injection nozzles (24), especially for motor vehicles and especially during manufacturing checks, wherein test fluid (32) is injected by an injection nozzle (24) into a measuring chamber (30), whereupon a piston (16) which at least partially defines the measuring chamber (30) is set into motion. The movement of the piston (16) is detected by a detection device (42) which delivers a corresponding measuring signal (48). A useful variable (Vn) and at least one defect variable (Ve) are obtained on the basis of said measuring signal in order to increase measuring accuracy, the useful variable (Vn) substantially corresponding to the actual injection quantity (mi).

摘要： A device (10) serves for the measurement of the injection amount from injection systems (16), in particular for motor vehicles and in particular in the production check. The device (10) comprises a measuring chamber (14), a coupling device, by means of which at least one injection system (16) may be coupled to the measuring chamber (14) in a sealed manner. The device (10) further comprises a piston (26), retained in a displaceable manner in a guide device (18) and which partially defines the measuring chamber (14). Furthermore, another sensor (50) is provided, which, on an injection by the injection system (16), measures a displacement of the piston (26). According to the invention, the accuracy may be increased, whereby the piston (26) is at least essentially closed and of hollow interior.
