Abstract
A micro-pump for fuel injection includes a housing, a pressure regulator, a combustible liquid inlet conduit in fluid communication with the pressure regulator, and a drop ejector on the housing and in fluid communication with the pressure regulator. The drop ejector contains a nozzle capable of ejecting a combustible liquid in a drop-by-drop fashion from the drop ejector. Further, an apparatus for generating a combustible vapor for a combustible fuel device such as an internal combustion engine. The apparatus includes a micro-pump for ejecting a combustible liquid drop-by-drop therefrom and means, connected to the micro-pump, for channeling a stream of air through the drops ejected by the micro-pump thereby generating a combustible vapor for the combustible fuel device.
