Diesel engine performance br br and emissions are closely related to fuel atomization and spray processes, which in turn are br br strongly influenced by nozzle geometry. br br Injection nozzles for diesel engines inject the fuel into the combustion chamber, atomize it br br and seal the combustion chamber by means of the nozzle needle. In the Common Rail System, the br br injection nozzle is part of the injector.
