Abstract

The present patent application refers to a double layer fuel injector atomizer for automotive mixture preparation systems, in which the fuel injector can generate a spray pattern, which may be shaped in a desired form to create an appropriate spray momentum without the use of any auxiliary mechanical adaptor on the downstream side of the atomizer.
