Model: CRDI Mini 786

The Mini CRDI 786 test bench is a dedicated common rail injector testing bench designed for quickly testing all kinds of common rail injectors of Bosch, Delphi, Denso and Siemens make (Both of Solenoid and Piezo technology). 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. The user can vary the pressure developed in the system from 0 - 1800 BAR by controlling the percentage opening of the Pressure control valve / solenoid mounted on the fuel rail fitted on this bench. The bench comes fitted with the Common rail injector and pump simulator (CRT 5000) 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. (For complete details on the CRT 7000 system please refer below to the section - CRT 7000 simulator details.

Test Bench Specifications and Features :

• Main Motor : 3 HP, Single Phase - 220 V OR 110 V (According to customer requirement)
• Delivery 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 timer, to take readings the user can enter the desired time for which the reading has to be taken and then push a green push button provided on top of the timer to start delivery and back leak measurement from injector. The test then automatically stops once the set time expires. The tubes can then be electrically drained via a push button on the bench.
• Injector Output delivery and Return pipes and adapters are provided with the bench which connect the CR injector output and return to the measurement test tubes.
• The test bench comes fitted with a Bosch CP1 common rail pump which is coupled to the motor and is responsible for fuel supply. 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 - 1800 BAR by controlling the percentage opening of this solenoid / control valve through the CRT 5000 system. 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.
• The test bench comes complete and fitted with all high pressure pipes, electrical couplers for all kinds of common rail injectors, and all necessary accessories to enable trouble free and speedy CR injector testing.
• 180 Degree rotating and swiveling injector console; the CR injector can be mounted and fixed in any user desired position (from 0 to 180 degree).
• The injector test 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 tests etc. as the pressures involved in CR testing are very high.
• The bench is fitted with a digital timer; to take delivery readings the user can enter the desired time for which the reading has to be taken and then push a green push button provided on top of the timer to start delivery and back leak measurement from the CR injector. The test then automatically stops once the set time expires.
• Diesel Fuel Tank Capacity on the bench is 5 liters. The fuel tank can be filled from outside without opening the bench.
• Dimensions : L X W X H - 76 X 62 X 68 (In centimeters / cm)
• Net Weight : 80 KG 

Model: CRDI 786 C

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 flow meter 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. 

User can save and print CR test results by attaching a USB printer to the test 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.
