Abstract: A fuel delivery system for a vehicle includes a fuel injector that dispenses heated fuel flow and controls the temperature of the heated fuel within a desired temperature range. Fuel flowing through the example fuel injector is inductively heated by a valve element sealed with the fuel flow. A driver controller detects changes in temperature by monitoring changes in parameters that vary responsive to temperature in the material of the heated element. Changes in the material responsive to temperature are utilized to tailor input into the heated element to maintain a desired temperature of the heated element and thereby the temperature of the fuel.

Abstract: A fuel delivery system for a vehicle includes a fuel injector that meters fuel flow and provides for pre-heating fuel to aid combustion. A control circuit including a synthetic inductor drives a heated element within the fuel flow.

Abstract: An ignition assembly includes a power converter receiving an alternating current input, including a first capacitor and a second capacitor. The first capacitor and the second capacitor are charged in parallel to a first DC voltage and at a first polarity to discharge in series to an output at a second DC voltage that is greater than the first DC voltage. The second DC voltage is coupled to an ignition gap, and causes the ignition gap to ionize and form a spark. A switch is coupled to the first capacitor and is operable to control the discharge of the first capacitor and the second capacitor. An AC input switch is coupled to the AC input and is operable to control a flow of current from the AC input through the first capacitor and the second capacitor to the output. The flow of AC to the output sustains the ionization of the ignition gap.

Abstract: A method and apparatus for a power converter assembly charges a first capacitor and a second capacitor in parallel to a first voltage and at a first polarity, and then discharges the first capacitor and second capacitor in series at an output voltage that is greater than the input voltage and at a second polarity that is opposite the first polarity. This “charge pump” process is repeated and filtered to produce a continuous output.

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.

Abstract: Sensing magnetic flux in an electromechanical actuator having dual axially opposed stators and dual springs, a control system modifies the rise of flux in such a manner to produce a substantially zero velocity landing of an armature against the stators. The flux is sensing by means of a sensor such as a hall effect sensor that is mounted each stator. The control system controls the flux rise when the armature is within the landing zone of the armature against the stator to match the spring rate of axially opposed springs in the actuator.
