This is a one day technical course covering fault finding and diagnosis of common rail diesel fuel systems. Course content includes the following subjects:

.

• Common rail main features and functions.
• Overview common rail system variants.
• Low and high pressure fuel supply.
  
• High pressure fuel pumps and pump diagnosis.
  
• Fuel metering regulation.
• Fuel high pressure control.
• Fuel pressure sensor circuit.
  
• Injectors: operation, testing and diagnosis (including piezo injectors and coding).
  
• Engine management control functions.
• EOBD.
  
• Fault finding and diagnostic techniques.
  

Course aims are to explain the operation of common rail diesel fuel systems and how to diagnose system faults.

During the course, delegates learn how to test the common rail diesel fuel system using diagnostic equipment and oscilloscope in conjunction with wiring diagrams and available technical information systems. Workshop sessions are carried out on live vehicles and working engine rigs.

By the end of the course, delegates will have gained knowledge and skills that should be useful to them when diagnosing common rail diesel fuel systems.
