Abstract

See full text

A method and apparatus for producing laminar flow through a fuel injection nozzle are provided. The method may comprise the steps of: providing a housing defining a cavity; providing a nozzle assembly having a first portion and a second portion extending from the first portion, the nozzle assembly being disposed within the cavity; placing the nozzle assembly in a closed position wherein the nozzle assembly is engaged with a valve seat defined by the housing; displacing the nozzle assembly and moving the nozzle assembly in an open position; expelling fuel through a gap defined between the second portion of the nozzle assembly and the housing, wherein the gap is sized to restrict fuel flow and create a laminar flow output stream having a Reynolds Number of equal to or less than 2000. The method may further include the step of returning the nozzle assembly to the closed position.
