Guided tests April

18/04/19

As part of our continuous upgrade process, we are pleased to announce updates to our common rail diesel rail pressure control guided tests. The test guidance describes how to connect and obtain waveforms so you can diagnose system faults that might be causing unexpectedly low or high fuel rail pressures.

CRD (Bosch) pressure regulator valve – voltage
The purpose of this test is to evaluate the correct operation of the Bosch Common Rail Diesel (CRD) Pressure Regulator Valve (PRV) based on the voltage and duty control under engine run conditions.
 

CRD (Bosch) quantity control valve – voltage
The purpose of this test is to evaluate the correct operation of the Bosch Common Rail Diesel (CRD) Quantity Control Valve (QCV) based on the voltage and duty control under engine run conditions.
 

CRD (Bosch) fuel rail pressure sensor – voltage
The purpose of this test is to check the fuel system pressure characteristics on a common rail diesel engine by using the fuel rail pressure sensor.
