Abstract

Systems and methods are provided for a direct-injection engine having at least one cylinder head comprising at least one cylinder, in which each cylinder is assigned an injection nozzle which: is at least connectable to a fuel reservoir which serves for storing fuel, is secured in a nozzle holder, and is fitted with a nozzle needle which is displaceable in the direction of a longitudinal axis in a nozzle needle guide and, opens up at least one nozzle hole in order to introduce fuel. A control piston may be mounted movably on the injection nozzle, is displaceable in a translatory manner along the longitudinal axis of the injection nozzle between an inoperative position and a working position, and closes at least one fluid connection in the inoperative position and opens up same in the working position in order to introduce water into the associated cylinder.
