Abstract
A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle situated in a nozzle body, the valve needle being actuable by an actuator and acted upon by a restoring spring in such a manner that a valve-closure member which is in operative connection to the valve needle and faces the combustion chamber is kept in sealing contact with a valve-seat surface in the non-actuated state of the actuator. A first jet-opening angle αis assigned to a first lift state of the valve needle and a second jet-opening angle αto a second lift state of the valve needle.
