CPN type of electronic controlled high pressure pump tester core driving module using ST ( st ) current modular control chip, fully equivalent to the Bosch EDC7 electronic control system for high-pressure pump control, built-in current protection system users can rest assured that the use of. Rail pressure, and the drive current digital display can directly observe the rail pressure and current change, contribute to the repair of common rail pump fault diagnosis.

Function introduction:

For the detection of electronically controlled high pressure pump pressure build up and seal performance testing, judging whether there is fault of high pressure pump.

For the detection of rotor type electronically controlled high pressure pump flow stability.

Straight type electronic controlled high pressure pump cylinder bit flow uniformity testing.

Rail pressure sensor can test whether the failure, and linearity.

Detection of common rail pressure limiting valve leaks and high pressure bearing capability.

Fuel metering method can detect the presence of clamping stagnation and coil is burned.

In the running state of engine starting, idling, on-line detection speed, high speed rail pressure to help repair personnel to judge the fault.

In the different engine speed control the rail pressure, such as start condition, idle speed, medium speed operating condition, high speed mode.

In the engine forced control high pressure pump for repair of rail pressure, common rail pressure relief valve jamming caused by failure, such as engine speed can only be maintained at 1500 or 1700, available CPN electronically controlled pump tester of coercive control rail pressure, to detect and judge the fault.

Can be used in homemade common rail test bench, or in old test refitting common rail test bench, electronically controlled high pressure pump by CPN tester control the rail pressure, common rail injector by the fuel injector tester control of injection quantity and frequency, the injector sprays out of the oil through the oil collector is introduced into the glass tube through the contrast test, parameters of injector is qualified. A simple and practical common rail test bench, for small and medium sized pump adjusting shop master provide economic and affordable to everyone, small investment return.

Through the use of CPN type high pressure pump tester for high pressure pump, can help the user good correct judgment of diesel common rail engine speed, engine development process, speed fluctuated, insufficient power, black smoke, fuel consumption, difficult starting, whether the fault is caused by high pressure pump. Is the repair of electronically controlled high pressure pump necessary testing instrument.
