The injector of the Common Rail System contains the injection nozzle, an actuator in the case of piezo injectors or a solenoid valve in the case of solenoid injectors plus the hydraulic and electrical connections to trigger the nozzle module. An injector connected to the rail via a short high-pressure line is installed in each engine cylinder.
The electrical, hydraulic servo system in the injector receives control impulses from the EDC (Electronic Diesel Control) to open and close the nozzle module. It is triggered either by a solenoid-valve or a piezo actuator. Injectors with a piezo actuator can have a slimmer design and achieve reduced switching noise. Both technologies achieve similarly short switching times and permit pilot, main and secondary injections. In this way, fuel combustion can be designed to be efficient and clean at all operating points.
