COMMON RAIL injector and pump testing kit ZCR-4 PRO

The kit consists of COMMON RAIL tester TCR-4 and COMMON RAIL injector tester ICR-4.

COMMON RAIL tester TCR-4

TCR-4 tester is intended to diagnose the Common Rail injection systems. It is used to read values from the high pressure sensor and to control two control pressure valves at a time.

It can be used both to read the pressure and to control the control valves in a car as well as to diagnose the high-pressure pumps on the table. It is necessary to monitor the pressure in the container, thanks to which it is possible to assess adequately the state of the high pressure pump.

This tester can also be used to monitor the fuel pressure in the FSI-type injection systems.

Parameters of the tester

Function of the Tester TCR-4:

1. Range of the Sensor

   This function allows you to enter the maximum working pressure (Pmax) of the high-pressure sensor, which is used in a tested car.

2. Test of the circuits

   After selecting this function, check the continuity of the following circuits:

   - High pressure sensor circuit
   - Circuit of the valve 1
   - Circuit of the valve 2

   In order to test the continuity of each circuit, the tester is able to give an answer if the circuit correctly responds to a specific test signal.

   In case of the test of the high pressure sensor circuit, the result does not give the absolute certainty about its error-free operation throughout the range of working pressures up to the pressure Pmax. Complete confidence can be obtained by observing the reading of the pressure sensor during the engine operation.

3. The pump test

3.1. High Pressure Reading

Current pressure is read by the sensor of high pressure.

3.2. Additional functions

• function (a) - pressure pulsation - a maximum value of pressure changes within a specified period of time,
• function (b) - maximum pressure - is the maximum value of the pressure from the moment the measurement was started or from the moment it was brought to zero by an optional change of the control potentiometer position,
• function (c) - the pressure to be stabilizes by means of valve 1 - it is a constant reference pressure value, which the tester is trying to maintain by regulating the first valve control signal. Changes of this value shall be made with the control potentiometer. The accuracy of changes can be adjusted by pressing the appropriate button.
• function (d) - the pressure to be stabilized by means of valve 2 - it is a constant reference pressure value, which the tester is trying to maintain by regulating the second valve control signal. Changes of this value shall be made with the control potentiometer. The accuracy of the changes can be adjusted by pressing the appropriate button.

3.3. Changing the control valve 1

The change of the signal is performed with a control potentiometer. The accuracy of the changes can be adjusted by pressing the appropriate button.

3.4. Changing the control valve 2

The change of the signal is performed using a control potentiometer. The accuracy of the changes can be adjusted by pressing the appropriate button.
 

COMMON RAIL injector tester ICR-4

• Use of the tester

• Parameters of the tester

• Function of the tester

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.

Change of the value of the simulated injection time
The parameter "time" defines the time of injection of the injector. This parameter change ranges from 0.1ms to 5.0 ms. Changes can be performed every 0.1 ms or every 1ms.

Programming the number of sequences
The "Number" 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:

• pre-injection time: 0.2ms
• time between the initial injection and the main injection: 1ms.

If the parameter is set to "No", the initial injection will not be executed.

NOTE:
It is possible to buy the strobe lamp to go with the tester.
