Abstract: A method of controlling motion of a spool in a fuel injector is provided. A first current is provided on a close coil of the injector. A second current is initiated on an open coil of the injector while providing the first current. The first current is reversed after the second current reaches a saturation point. The first current is discontinued. The spool moves to the open position. The second current is discontinued with the spool in the open position. A third current is initiated on the close coil. A fourth current is provided on the open coil after initiating the third current. The fourth current on the open coil of the injector is reversed after the third current on the close coil reaches a saturation point. The fourth current is discontinued. The third current is discontinued with the spool in the closed position.
