Some advanced common rail fuel systems perform as many as five injections per stroke.
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.
