Bosch Injector Nozzle Catalog DLLA155P1493/0 433 171 921 for MERCEDES-BENZ 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 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.
