Common Rail Injector Shims kit for Repairing Bosch injectors

 

Common rail injection has been in existence for a long time but has become more popular in diesel engines over the past decade. By far the greatest advancement over the past 10 years in engine design has been the development of the High Pressure Common Rail (HPCR) fuel injector. These remarkable devices have been the cornerstone for advances in combustion efficiency and allow an engine to achieve the stringent new emissions levels proposed by the engine Tier ratings.


Modern HPCR fuel injection systems are practically simple in their overall designing, however, they comprise a number of highly complex interacting key components in order to function reliably and efficiently. The main HPCR components are listed and illustrated in the image below. Unlike older Electronic Unit Injector (EUI) designs, the HPCR fuel injector does not develop its own pressure during engine operation.
