Common Rail injectors make possible fine electronic control over
the fuel injection time and quantity, and the higher pressure that
the common rail technology makes available provides better fuel
atomization. In order to lower engine noise, the engine's
electronic control unit can inject a small amount of diesel just
before the main injection event ("pilot" injection), thus reducing
its explosiveness and vibration, as well as optimizing injection
timing and quantity for variations in fuel quality, cold starting
and so on.
common rail engine parts
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.
common rail injector repair kits
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.
China-Lutong Nozzles are designed to withstand the heavy demands of
todays diesel engines. On average, a diesel nozzle fires 1,000
times per minute, so precision and durability are important
features. Each China-Lutong Nozzle is engineered for exacting
precision and durability, to deliver a long, reliable service life
for consistently superior diesel engine performance.
China-Lutong Nozzles are 100% factory tested and calibrated to
specifications using the same test equipment to insure the highest
level of performance and cleanliness compliance. As a result,
customers receive high quality products - not only the first time,
but every time

Common Rail is now the most common fuel system in diesel vehicles.
Diesel engine performance and emissions are closely related to fuel
atomization and spray processes, which in turn are strongly
influenced by nozzle geometry.
Injection nozzles for diesel engines inject the fuel into the combustion chamber,
atomize it and seal the combustion chamber by means of the nozzle
needle. In the Common Rail System, the injection nozzle is part of
The injection nozzle consists of the nozzle body the cone of which
protrudes into the combustion chamber. The injection orifices
through which the fuel is injected are bored in the nozzle cone.
The number, configuration, length and diameter of these injection
orifices permit the shape of the injection spray to be formed in a
way that is ideally matched to the engine cylinder.
Inside the nozzle body is the nozzle needle which, when closed,
blocks the injection orifices. For fuel injection, the nozzle
needle is raised by the hydraulic servo system of the injector so
that the injection orifices are opened. The faster the nozzle
needle can be opened and re-closed, the more precisely the
injection rate can be controlled.
The injection rate and the shape of the injection spray have a
decisive influence on fuel consumption and raw emissions from the
