Abstract

A device is provided which allows exact apportioning and controllable atomization of fuel as necessary for various operating conditions of an internal combustion engine. The apportioning ensues with an apportioning aperture that can be closed via a valve needle. Separately therefrom, the atomization ensues with a piezoelectrically driven nozzle having an atomizer orifice placed into vibration. The shape of the atomizer aperture can be round, triangular, quadrangular or cross-like.
