Abstract (en)

[origin: WO02054038A2] 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.
