Patent attributes
A fuel injector for an internal combustion engine includes a valve body 14. A valve seat 18 is associated with the valve body. The valve seat defines an outlet opening 24 through which fuel may flow. An armature 38 is associated with the valve body and is movable with respect to the valve body between a first position and a second position. The armature is associated with a closure member 24 proximate the outlet opening and contiguous to the valve seat when in the first position, and spaced from the valve seat when in the second position. An electromagnetic coil 44 is energizable to provide magnetic flux that moves the armature between the first and second positions to control liquid fuel flow through the outlet opening. A heating coil 50 is energizable to provide heat and thereby vaporize liquid fuel as it exits the outlet opening.
