Abstract:
1. A testing device for high-pressure injectors of a common rail injection system of an engine unit, comprising: high-pressure injectors each having a fuel return connection for a fuel return line, and a throughflow quantity measuring/display unit which can be detachably connected between the fuel return connection and fuel return line, wherein for every high-pressure injector of the engine there is available one throughflow quantity measuring/display unit, a first flexible hose unit that is arranged between the fuel return connection and the throughflow quantity measuring/display unit, and a second flexible hose unit that is arranged between the throughflow quantity measuring/display unit and the fuel return line, wherein every high-pressure injector in the engine unit is connected to a throughflow quantity measuring/display unit such that defects of each high-pressure injector within an overall fuel circuit can be measured based on the flow quantity of fuel in the return line of each high-pressure injector.
