Common Rail is now the most common fuel system in diesel vehicles. Deeper knowledge of how common rail fuel system technology works across vehicle makers and system manufacturers is a big advantage when it comes to troubleshooting.


This training module starts by covering the basics of operation and requirements for fuel ignition in the combustion chamber. It then examines the whole fuel system from tank to injector, covering the key components and how they operate. Special focus is given to adjusting the injection pressure. The module also delivers clear explanations for high-pressure and flow control, and how they work in combination.

The final part of the training module covers troubleshooting. Problems are often indicated by fault codes or symptoms, but this module will teach you how to build up a full picture by checking mechanical operation and fuel flow first. Simple tips and methods are provided to help you reach correct conclusions and carry out your work in a logical sequence.


To reach all learning outcomes you need to have a basic knowledge of diesel engine mechanical structure and operation. Troubleshooting experience will also help you to understand how to apply the learning in practice.
