ICR-4 tester is used to control electromagnetic and piezoelectric injectors used in the common rail injection systems. It is possible to control up to four injectors of a type at a time. The signal generated by the tester which controls the injectors, corresponds to the signal which appears in the car engine controller.
|Supply voltage||DC 12 ... 15V|
|Current draw||up to 4A (fuse)|
|Number of controlled injector|
|Parameters of the simulated injection|
|frequency||36 ... 4800 /m (change in steps of 10 /m)
0.3 ... 40Hz (for every injector)
|pulse||100 ... 5000 mks (change in steps of 10 mks)|
|Programming the number of rpm||yes|
|The option of the initial injection||yes (at frequences 36 - 2400 /m or 0.3 - 20 Hz)|
After connecting the power supply, the tester displays the splash screen:
After you start the injectors, the tester performs a sequence of injections in the quantity indicated by the parameter "Quantity".
Change of the value of the simulated engine speed
The parameter "Speed" indicates the simulated value of rpm. This value is the real value of the car's engine speed, so that the injector injects half as many times. The range of changes of this parameter ranges from 30 rpm to 2500 rpm.
Programming the number of sequences
The "Quantity" parameter specifies the number of injection sequences to be performed. A sequence of injections is meant to be four injections, one for each injector. The tester always performs the total number of the injection sequences. This parameter change ranges from 0 to 9999. Changes can be performed every 10 or every 100.
The tester performs the set number of sequences and indicates the number of the sequence, which is being currently performed on the display. After the performance of the set number of sequences, the tester stops its operation.
Simulation of the initial injection
The "initial" parameter enables the simulation of the initial injection. If the parameter has the "yes" value, the pre-injection will be performed before each injection. The pre-injection parameters are fixed at:
