The device FLAGMAN “CRTester. CRT-5040 ” is designed to diagnose CommonRail injectors manufactured by Bosch, Denso, Delphi, Siemens VDO on the test bench. Injector testing is provided by feeding the control signal from the controller to the tested injectors and maintaining the required pressure in the system according to the selected test plan.

The device provides:

simultaneous control of 1-4 injectors;
pressure control in the system in manual and automatic mode;
control of electromagnetic injectors of the passenger car with a voltage of 14V;
control of electromagnetic injectors of the cargo series with a voltage of 28V;
control of piezoelectric injectors;
control of the measuring unit shutter;
disabling control in the absence of a safety screen in the test area;
control of the HP pump drive stopping after the end of the test;
temperature measurement in the tank;
measuring the injector backflow temperature;
measuring the timing of the injection;
control of the cooler and heater;
control of the injector flow and backflow measurement.

• Common-Rail HP pump (Common Rail systems CP1, CP3) control;
• frequency converter control ;
• control of the frequency and direction of the HP pump drive;
• Functions are additional options and are not included in the basic version of the device!

Dieselland is manufacturing special tools and equipment for various diesel fuel systems.

TRIUMF benches are manufactured with the possibility of retrofitting with a hardware and software complex for encoding Bosch, Delphi, Denso injectors. To encode the Delphi injectors, a device is additionally installed, which allows to create a vacuum in the backleak line of the injector. The set of the vacuum creating device is a gear pump, a venturi tube and an electric motor. The device is installed on the bulkhead, which is located in the lower part of the bench above the cooling unit.

As a working fluid in the test bench, a test liquid of ISO 4113 standard is used. The source of high pressure is a high-pressure fuel pump (HP pump), which has a drive from an asynchronous motor of 4 kW, 1500 rpm. As a feed pump, a gear pump is used, integrated into the injection pump housing and having the same drive.

The vacuum creating device is mounted on a separate gear pump, which is located at the bottom of the bench above the cooler.

For thermostabilization of the test liquid in the tank, the following applies:

• two radiators with forced air cooling for the backleak line from the injection pump and the -backleak line from the pressure accumulator (rail).
• independent cooler with air heat exchanger.
• 1000 W tubular electric heater

Working pressure up to 1800 bar. It is possible to increase the working pressure to 2400 bar.

The bench has an electronic measuring system with the possibility of simultaneous testing of 4 injectors.

The program with test plans is included in the set of delivery. Software updates, including new test plans, are published twice a year and are provided free of charge.

The test bench allows checking the following equipment of the COMMON RAIL system: BOSCH, DENSO, DELPHI injectors, (SIEMENS optional), BOSCH, DENSO, DELPHI, SIEMENS pumps (CP1, CP2, CP3, HP2, HP3, DFP1, DFP3, DFP6, HP3, HP4), regulators and pressure sensors. The operating pressure of the test is up to 1800 bar. At the request of the customer,there is possibility to increase the working pressure to 2200 bar. Test bench is equipped with an electronic measuring system. Test bench includes a software with built-in test plans.

CRistina repair- and testing complex is dedicated to assembing and disassembling Bosch, Denso and Delphi Common Rail inejctors according to manufacturer specified steps and mechanical tolerances. The complex offers the ability to measure relevant mechanical tolerances of the injector parts and electrical characteristics of the electromagnet. The assembly/dissembly steps and critical measurement points are presented by convenient step-by-step instructions descriptions and relevant images of the work process itself.
