mon Rail is now the mon 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 bustion chamber, atomize it and seal bustion chamber by means of the nozzle needle. In mon Rail System, the injection nozzle is part of the injector.

The injection nozzle consists of the nozzle body the cone of which des into bustion 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.
