CR-A Rail Pressure Tester A simple measurement accuracy, the lifting of the conventional mechanical pressure gauge to be connected to the pressure tube to bring the complex operation, disassembly pressure tube caused by foreign matter into the damaged injector disassembly tubing caused pipeline damage, oil spills, and so causeThe series negative impact. Using the instrument and greatly improving the work efficiency. The most important is based on the standard data to find inadequate engine starting difficulties and power engine failure alarm.
Using the standard conditions of the handheld instrument supporting rail pressure data, and the other with detailed instructions, quick guide maintenance personnel to find and repair the fault. Truly become an indispensable diagnostic instrument for testing and repairing common rail engine.

ON: Turn on the instrument
OFF: Turn off the meter
Usage:
1,Online testing methods
Engine rail pressure sensor unplug series tester picture-line.
Open instrument of power, running the engine observation instrument digital display rail pressure value changes.
Please note that the direction of the locating pin docking plug, otherwise it will cause the sensor is damaged or the plug is damaged.
2,Directly test
The engine stops running, unplug the original car rail pressure sensor plug, plug in the instrument wiring harness plug, observe rail holding pressure.
Bosch common rail system rail pressure data:
| Shows rail pressure | Status |
Idle | 250-350BAR | System rail pressure normal |
>550bar 480-540bar | System failure 1, the fuel metering valve sticking 2 injector valve assembly leaking oil return excessive 3, the rail pressure pressure limiting valve leak 4,Low oil clogging | |
Unstable rail pressure fluctuated | System failure 1, Low oil into the air, or the high-pressure pump damage 2, the fuel metering valve catching or harness poor contact 3, built-in injector Inlet spear leak | |
Accelerate | 350-15000BAR vary | With the fuel door and change the rail pressure |
600-800BAR | System failure 1, rail tube pressure limiting valve failure or open 2, the fuel metering valve control failure 3, the fuel metering valve wear | |
Reduce speed at high speed | Reduced to 250-350BAR | System rail pressure normal |
490BAR-510BAR Range of slow | The Injector back to oil excessive The high pressure pump cavity pressure instability |
Maintenance and Notes
1, in order to ensure the instrument life, the instrument should not be placed in direct sunlight to use location should be relatively flat, non-wrestling, hitting
Do not use strong solvents (such as: benzene, nitro-class oil) to clean cabinet
3 meter external interface to strictly use the instructions in the labeling method used, are not allowed to change the join. If any damage caused by incorrect insertion manufacturer takes no responsibility!
