Common Rail Injector, Pump and Fuel Rail Test Bench

Model - CRDI 786 C

Introduction and Features:-

    -  The CRDI 786 C test bench is a 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  (Injectors of both Solenoid and Piezo technology can be tested). User can test up to 2 injectors at a time / simultaneously. This model can also be setup to test 4 CR injectors at a time at some extra cost.   

    -  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 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. Common Rail Pumps that can be tested include Bosch CP1 / CP2 / CP3, Delphi CRSP, Denso HP0 / HP3 / HP 4 and the Siemens DCP pumps. User can also measure pump fuel return flow with the flowmeter mounted on the test bench.  

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

    - Test bench comes complete with computer hardware, bench software and all CR injector and pump test plans for Bosch, Delphi, Denso and Siemens. All common rail testing parameters can be controlled from and monitored on the computer software screen. 

    -  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 also set the injector Pulse width, W (Which controls the volume of delivery per spray) and Frequency of spray (Which is the number of sprays per second) of the CR injector to simulate different testing conditions. The pressure in the system is read from the pressure sensor on the fuel rail constantly and is displayed digitally on the CRT 7000 LCD screen (See image 3 above). (For complete details on the CRT 7000 system please refer to the listing of the same on eBay, item number: 320746771024).

Test Bench Specifications:-

·        Main Motor (Make – ABB Motors): 5 HP, Single Phase – 220 V OR Three Phase 415 V, 50 / 60 HZ or as per customers requirement. 

·        Drive (Make – Schneider Electric): The CRDI 786 is fitted with a Schneider AC Frequency / Electronic drive.

·        Test Bench RPM: The user can set the desired RPM of the test bench anywhere from 0 – 6000 RPM. With electric push buttons to increase / decrease speed of the bench. 

·        Injector Output Delivery & Return Measurement: Injector output delivery and return / back leak is measured in test tubes fitted on to the bench. The bench is also fitted with a digital tachometer, through which the user can control the number of strokes and time for which the reading of Back flow / return vs. output delivery of the CR injector is recorded by the bench. The test then automatically stops once the set number of stroked are reached. The tubes can then be electrically drained via a push button on the bench.

·        CR Pump return measurement: A dedicated Rota meter (Flow meter) is installed on the CRDI 786 to measure the return delivery of all common rail pumps.

·        Pump return, Injector Output delivery / Return pipes and adapters are provided with the bench which connect the CR injector output and return to the measurement test tubes and the CR pump return to the Rota meter.  

·        The test bench comes fitted with a Bosch CP1 common rail pump complete with its coupling and a foundation which is suitable for all kinds of common rail pumps. The test bench is also fitted with a Bosch fuel rail fitted with a rail pressure sensor and fuel rail pressure control valve / solenoid. One can control the pressure in the system from 0 – 2000 BAR by controlling the percentage opening of this solenoid / control valve through the CRT 7000 system / test bench software. Also the pressure in the system is read and monitored through the pressure sensor fitted on the fuel rail and is displayed digitally on the LCD screen of the CRT 7000 and on the computer software screen.    

·        The test bench comes complete and fitted with all high pressure pipes, electrical couplers for all kinds of common rail injectors, pumps and fuel rails, and all other necessary accessories to enable trouble free and speedy CR testing.

·        The Common rail testing area is well shielded with an unbreakable transparent acrylic shielding box, which can be lifted up when desired. This is for the safety and protection of the operators when observing spray pattern / performing other injector and pump tests etc. as the pressures involved in CR testing are very high. 

·        The bench is fitted with a digital tachometer with stroke counter; to take delivery readings the user can enter the desired number of strokes for which the reading has to be taken.

·        Diesel Fuel Tank Capacity: 35 Liters

·        Dimensions: L X W X H - 150 X 58 X 160 (In centimeters / cm)

·        Net Weight: 380 KG 

·        Gross Weight (With Wooden packaging): 500 KG

·        Power Supply: Customizable as per customer’s requirement.

·        Comes complete with all Operation manuals, CR Injector and pump test data and a CD containing an excellent presentation and other useful information on Common rail technology.  

Note: Customization's are possible to the test bench if you desire, kindly feel free to discuss in case you want any.
