Dedicated Common Rail / CRDI Test Benches

Mini Common Rail Injector Pump and Rail Testing Bench

Model: Mini CRDI 101 C


Complete with all computer hardware, software and CR injector and pump test plans for Bosch, Delphi, Denso and Siemens.

Introduction : Introducing the World's Smallest dedicated Common rail injector, pump and fuel rail testing bench designed for quickly testing all kinds of common rail injectors, pumps and fuel rails of Bosch, Delphi, Denso and Siemens make.

Function / Application :
It can test CR Injectors of both Solenoid and Piezo technology - up to two at a time / simultaneously - It is used to diagnose the Faulty Common rail injector by testing it for its spray pattern, Output delivery to back leakage ratio, Full load delivery, No load delivery, etc. User can also measure the solenoid / Piezo sensor resistance of the injector.

Common Rail Pumps that can be tested include Bosch CP1 / CP2 / CP3, Delphi CRSP, Denso HP3 / HP 4 and Siemens DCP pumps. User can diagnose faulty common rail pumps if they are not developing sufficient pressure / if the solenoid (Fuel metering control valve) on the pump is not functioning well / return flow of the pump is too high. (Bench comes fitted with a Rota meter / Flow meter to measure the return delivery of common rail pumps)

One can also test the pressure sensor and solenoid (fuel rail pressure control valve / DRV / FCA) mounted on the fuel rail for proper function. User can also measure solenoid resistance of the DRV.

The user can vary the pressure developed in the system from 0 – 2000 BAR by controlling the percentage opening of the Pressure control valve / solenoid mounted on the fuel rail fitted on this bench through the CRT 7000 simulator installed on this test bench.

The bench comes fitted with the Common rail injector, pump and fuel rail simulator (CRT 7000) attachment through which user can control the following:-.

  • Pressure in the system (0 - 2000 BAR) by controlling the percentage opening of the fuel rail pressure control valve / solenoid / DRV from 0 - 100 %
  • The injector pulse width (W) - Which determines the volume of delivery per spray.
  • Injector frequency of spray / RPM of engine (N) - Which controls the number of sprays per second.
  • Monitor the fuel rail pressure (Also the system pressure) which is displayed digitally on the CRT 7000 LCD screen and also on the computer software screen , which is read constantly from the pressure sensor mounted on the fuel rail.

Extremely compact and light weight test bench, ideal for diesel workshops who intend to start common rail injector and pump testing. Also ideal for small workshops which have a space constraint to accommodate a bigger test bench. (Refer below for weight and dimensions)

Computer, keyboard and mouse fitted on to the test bench along with the CRT software to control and monitor all CR testing parameters.

User can save and print test results as well by attaching a USB printer to the test bench computer.

CRT 7000 Simulator Details:-
The bench comes fitted with the CRT 7000 simulator for driving common rail injectors, pumps and fuel rails, the complete details of which are provided below:-

Features:
  • It provides driving signals to the injector solenoid and can be used to test a CR injector for its delivery, back leak, spray pattern, chattering etc. One can easily measure the return to output delivery ratio on a test bench using the CRT 7000.
  • One can vary the pulse width of the injector (W) (in mS – milli seconds), which determines the time for which the injector nozzle opens to spray, hence determining the volume of delivery per spray. More the set pulse width, higher will be the output delivery.
  • Also one can vary the engine RPM (N) which in turn determines the frequency of spray from the injector (Number of times an injector sprays per second). Higher the set engine RPM higher will be the frequency of spray.
  • It provides driving signals to the fuel metering control valve / Solenoid on the CR pump, and can energize it from 0 % to 100 %, i.e. fully closed (zero output delivery) to fully open (maximum output delivery). The fuel metering control valve on the pump regulates the fuel intake volume to the CR pump and hence also determines the output volume.
  • The CRT also provides driving signals to the fuel rail pressure control valve / solenoid which is used to increase / decrease rail pressure by operating a drain / return mechanism to drain out fuel from the fuel rail. As in the case of pump solenoid, this can also be energized between 0 – 100 %. The Mini CRDI 786 bench is fitted with a Bosch fuel rail with a rail pressure control valve / solenoid which is controlled through the CRT 7000 unit on the test bench.
  • Monitors and displays the rail pressure digitally on the LCD display, and provides automatic cut off of fuel supply once rail pressure exceeds 1600 BAR (Overpressure protection). The fuel rail on the bench has a pressure sensor mounted on it and the pressure in the system is read through this pressure sensor and is displayed digitally on the screen of the CRT 7000 unit mounted on the Mini CRDI 786 test bench.
  • Hence the CRT 7000 is also used to test the proper operation of the fuel metering solenoid on pump, fuel rail pressure control valve / solenoid on rail and the fuel rail pressure sensor.


Therefore, the CRT 7000 is nothing but an ECU / ECM simulator - it simulates the working of an ECU / ECM in vehicles to provide precise driving signals to the various components of the common rail system, i.e., the CR pump, Fuel rail and the CR injectors. Also like the ECU it receives feedback from the pressure sensor on the rail and displays the rail pressure digitally.
