Expert InEx-2 is a device for comprehensive diagnosis of common rail injectors. It allows electrical and mechanical testing of the control parts of coils and piezoelectric injector stacks, along with evaluation of the intermediate system between the electrical and mechanical stages. The coil/stack drive option allows you to check on the test bench by simulating the operation of, for example, expenses. InEx-2’s technical capabilities allow the following tests:
– Simulation of injector operation with the following parameters: opening time, frequency (or RPM), number of injections,
– Selection of electrical parameters of the control: holding current, charging voltage of the piezo stack and the speed of this process,
– Accurate measurement of resistance of coils (milliohm range) and piezo stacks (kilooms) with automatic measurement cycle and memory for up to 8 measured injectors,
– Stack capacitance measurement, with parallel resistance measurement capability and result memory for up to 8 measurements,
– Determination of leakage current between ground and injector supply pin during high voltage test,
– Electromagnetic injector control for ball pitch measurement with selectable holding test current and time protection between measurements,
– Measurement of the dynamic response of common rail injectors, together with an assessment of the reliability of the measurement series
The device can be used to test injectors on test benches equipped with a common rail high-pressure pump. If your equipment does not have a pump control function, you can use the TCR-4 tester (insert link), which will ensure cooperation with your pump and allow you to conveniently inflict pressure.
