ABSTRACT:
A fuel injector has a shroud surrounding its valve orifice. The shroud carries a porous element spaced from the orifice to define a chamber. Air passages are provided through the shroud for injecting air under pressure into the chamber. The fuel sprayed onto the porous element from the orifice enters the pores of the element and increases the wetted surface area such that the air under pressure passing through the porous element shreds the fuel films and finely atomizes the fuel for egress from the porous element into the internal combustion engine.
