This test bench has been designed for testing fuel injection pumps at different ambient- and test fuel temperatures. The test bench simulates the mechanical drive, fuel supply and return circuits. It measures the pump torque, flow capacity and operating pressure on the pump depending upon supply pressure, rotation speed of the pump, ambient- and fluid temperature and inlet valve actuation.
The loading of the test samples is made by quick-changeover mechanism. The automatic test sequence can be defined by flexible test plans. Manual operations and measurements are possible as well.
This test bench includes fixtures for two injection pumps, which can be tested at the same time.
