FUEL INJECTION NOZZLE WITH CONTROLLABLE FUEL JET CHARACTERISTIC

摘要

An injection nozzle has a bore (13) and a needle (11) and a drive (91) with electric input parameters as well as a drive device (96) for an alternating lifting movement of the nozzle part (12), said lifting movement being overriden by the open state of the injection nozzle. The drive device (96) can be activated by electrical input parameters and is constructed so that at least one small time-interval which is many times smaller than the predetermined minimum opening time of the injection nozzle is available for the reversal of the lifting movement.
