Common Rail Injectors

Common rail injectors are high variant of direct fuel injection system for diesel engines. These injectors connect to a common rail fuel system, found in most modern diesel engines, injecting fuel into the cylinders at high pressure.

Within a diesel engine common rail injectors are feed by a high-pressure fuel rail that is controlled by the individual solenoid valves. As common rail valves operate at very high pressures so care must be taken when diagnosing the system. They are are an essential part of a modern diesel engine, similar to fuel injectors in petrol engines. The solenoid injector regulates the amount of fuel delivered into the combustion chamber.

The precise closing and opening of the common rail injectors is electronically controlled. Delphi Common Rail Injectors part numbers are normally on the outside of the body and format as follows: R***** or 28******.

Bosch Injector part number format as follows: 0 445 *** *** or 09** *** *** and can be found normally stamped on the top of the Injector.

Common symptoms of common rail injector failure are high fuel consumption, black smoke, rough running and poor starting.

Fault codes often related with common rail injector failure are: P2336, P2337, and P2338.
