Abstract (en)
[origin: EP1887214A2] The injector for a fuel injection system of an internal combustion engine comprises a nozzle needle (16) which is stroke-adjustable in an injector body (2) for controlling injection of fuel through at least one spray orifice (3). A piezoactuator (10) is arranged in the injector body for producing an actuator stroke, and a coupling device (21) is arranged in the body for stroke transmission between piezoactuator and nozzle needle. The nozzle needle is stroke-adjustable relative to the coupling device. An electromagnetic linear actuator (22) drives the nozzle needle in its stroke direction. An independent claim is included for a method for operating an injector in which for opening the nozzle needle the piezoactuator is deenergized and the linear actuator energized, and/or for closing the nozzle needle the piezoactuator is energized and the linear actuator deenergized.
