Abstract
A fuel injector for an engine includes a fuel volume having an air inlet port having a porous membrane. The membrane is permeable to air and impermeable to fuel whereby air inlet to the fuel volume forms a two-phase air bubble/fuel dispersion within the fuel volume. Upon actuation of the needle valve of the injector, this two-phase air bubble/fuel dispersion flows through the orifice into the engine whereby improved atomization, burn and fuel economy with resultant reduction in emissions are provided.
