Dual-coil electromagnetic injection valve

The present invention provides a fuel injector with an armature and a means for biasing the armature toward a first position. A primary coil is wound in a first direction such that, when energized, it develops a magnetic force that opposes the biasing means and causes the armature to move from the first position to a second position. A secondary coil is positioned coaxially with the primary coil. The secondary coil has an at least partially reverse wound portion wound in a second direction opposite the first direction, such that the magnetic field generated by the at least partially reverse wound portion at least partially cancels the magnetic field of the primary coil.
