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.
After connecting the power supply, the tester displays the splash screen:
Then, it automatically switches to the selection screen of the controlled injector type. The name "electromagnetic" stands for the electromagnetic injector, whereas "Piezoelectric" stands for the piezoelectric injector.
After selecting the appropriate type of the injector, the screen displays the currently set parameters of the injector control signal.
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:
NOTE: It is possible to buy the strobe lamp to go with the tester.
