he fuel nozzle sprays fuel into the engine cylinder in the form of atomization through
electromagnetic control or mechanical control.
2. Good atomization can make fuel and air mix more fully and improve the combustion quality.
3. It determines the injection speed and range of fuel and has an important influence on the
combustion process.
4. Accurately control the fuel flow according to the working condition and load of the engine.
5. Optimizing fuel injection can reduce harmful gas emission and meet environmental protection
standards.
★Features and Benefits:
All Injectors are completely end of line tested using the exact OE test equipment and
specifications.
Manufactured with the latest engineering updates so often times it is superior to the dealer
channel product.
Manufactured using all OE tools and process to provide guaranteed factory performance.

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
emissions goals of the market for which the engine is produced regardless of details of the fuel
system design (i.e., regardless if the?fuel system?is of the common rail, unit injector, unit pump
or pump-line-nozzle type). Additionally, specific requirements for injection nozzles can also
depend on the fuel system type :
Common rail-nozzle?operates under more demanding tribological conditions and must be better
designed to prevent leakage.
Unit injector/unit pump-pressure pulsing conditions create more demanding fatigue strength
requirements.
Pump-line-nozzle-hydraulic dead volume must be minimized.
