CRUIS – Equipment for Common Rail injectors

CRUIS Equipment 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 2400 bar.

The Equipment has an electronic measuring system with the possibility of simultaneous testing of 1 injector.

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.


Features and characteristics of the test bench:

  • testing of single injector with simultaneous measurement of “flow” and “backflow” in two independent measuring modules
  • electronic measuring system
  • the frequency of the injector opening pulses (60 – 1500 rpm);
  • duration of the injector opening pulse (100 – 3000mcs);
  • temperature control of the test fluid in the range 0-100 ± 1 deg.C
  • control of the test liquid pressure in the range: 0 – 2400 bar with the possibility of increasing the pressure to 2400 bar
  • electronic pressure measurement in the fuel pressure accumulator in the range: 0 – 2400 bar with the possibility of increasing the pressure to 2400 bar
  • temperature control of the test fluid on the injector
  • safety screen of polycarbonate (h = 10mm)
  • dimensions: width 1040, height 1700, depth 560 mm
