The 3rd generation of Common Rail makes diesel engines even cleaner, more economic, more
powerful and quieter.
The key is the innovative injection system: it works with rapid switch, compact
piezo-inline injectors.
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
asolenoid-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.
Diesel Fuel Injector Nozzles Introduction
Design of the diesel fuel injector nozzle is critical to the performance and emissions of
modern diesel engines. Some of the important injector nozzle design parameters include details
of the injector seat, the injector sac and nozzle hole size and shape. These features not only
affect the combustion characteristics of the diesel engine, they can also affect the stability of the
emissions and performance over the lifetime of the engine and the mechanical durability of the
injector.
All nozzles must produce a fuel spray that meets the requirements of the performance and
