1.Product introduction

EPS208 Type high pressure common rail test bench is a common rail test product using all-in-one control system, real-time control and measurement. At the same time, it provides the control signal of Bosch, Denso, Delphi and Siemens to drive the high-voltage common rail injector for work. The system is equipped with standard drive signal parameters, and users can also adjust the parameters according to their actual situation and save them. Such as pressure, time, speed and other parameters, all LCD screen display, reliable work, high control accuracy. It is the ideal equipment for diesel automobile, internal locomotive maintenance, production and testing.

2.Main functions

High-pressure common rail test bench imitates diesel engine ECU (Engine Control Unit), 

and provides common rail system control signals (CP1/ CP2/ CP3/ HP3/ HP4/ DELPHI), 

such as Bosch, Denso, Delphi, and Siemens, to drive high-pressure common rail.
The oil pump and the high-pressure common rail injector are working, 

and the driving signal parameters can be set by the user according to their actual conditions, and can be grouped and saved, 

which is convenient for maintenance personnel to judge and repair the working state of the high-pressure common rail system.

The power of the EPS208 high-pressure common rail test bench is 2.6KW.
