ABSTRACT:
A fuel injector for an internal combustion engine including a body, a stator member, an armature, an electromagnetic coil, and a diamagnetic member. The body includes a passage extending along a longitudinal axis between inlet and outlet ends. The armature member is movable with respect to the stator member between a first configuration and a second configuration, and includes a closure member proximate the outlet end and contiguous to a seat in the first configuration, and spaced from the seat in the second configuration. The electromagnetic coil surrounds the passage, is disposed in a housing, and is energizable to provide magnetic flux that moves the armature between the first and second configuration to permit fuel flow through the passage. The diamagnetic member is proximate the electromagnetic coil so that when the electromagnetic coil is energized the magnetic flux flows around the diamagnetic member.
