Abstract
A fuel injector nozzle assembly includes an injector body including a valve seat with a supply passage through which fuel flows generally along a supply axis. A nozzle plate is mounted onto the valve seat and includes a plurality of orifice holes therein through which fuel flows. A turbulence cavity is defined by the nozzle plate and the valve seat wherein fuel flows into the turbulence cavity through the supply passage and out from the turbulence cavity through the plurality of orifice holes. A plurality of obstructions are located within the turbulence cavity directly in front of the orifice holes and are adapted to create turbulence eddies within the flow entering the orifice holes.
