An injection nozzle for an internal combustion engine, having a nozzle body with a first nozzle needle for controlling at least one first injection opening and a second nozzle needle for controlling at least one second injection opening. A first drive piston is coupled to the first nozzle needle and is equipped with a first booster surface hydraulically coupled to a control surface of a control piston by a first hydraulic pressure transmission path, a second drive piston coupled to the second nozzle needle has a second booster surface that an activatable and deactivatable second hydraulic pressure transmission path is able to hydraulically couple to a control surface of the control piston; the activation and deactivation of the second hydraulic pressure transmission path is controlled as a function of the control piston stroke.
