The movement of the nozzle needle in the injector is generated no longer by a
solenoid coil but rather by a
piezo-element.
A piezo-element is an electromechanical converter, i.e. it consists of a ceramic
material which converts electrical energy directly into mechanical energy
(force/travel).
Special tools required:
