Fuel Injection Technology GDI EOL 2.0 Pump test bench

The machine offers a fully automatic testing of cam-driven high pressure fuel pumps. The mechanic drive and the low- and high pressure proof circuit are simulated by the test bench.

The test devices are automatically supplied to the machine by a conveyor system. Inside the test bench a gripper handling is used for the transport of the pumps. There is also a camera for detection of the serial numbers of the pumps.

The test is carried out in the measurement station. The automatic contacting of the test device inside the machine takes place on an easy changeable workpiece carrier.

The changeover to a different pump type happens by changing this pump-specific workpiece carrier. Hereby, a high flexibility of the test bench to different geometries of the low-and high-pressure connector and to the electrical contacting of the test device is assured.

The test parameters are adjusted through a data based flexible test plan system. The individual test steps can be positioned in any order and number and with different set point limits.

By means of the central database on a separate server PC it is possible to easily connect several test benches of the same type. All results are automatically stored and archived on the server.
