ABSTRACT:
An electronic high frequency induction heater driver, for a variable spray fuel injection system, uses a zero-voltage switching oscillator that is impedance coupled to an imbedded multiple function signal separator and integrated with a conventionally implemented electronic fuel injector driver. The induction heater driver, upon receipt of a turn-on signal, multiplies a supply voltage through a self-oscillating series resonance, and couples the high frequency energy to a high pass filter such that the useful energy is utilized in an appropriate loss component so that fuel inside a fuel component is heated to a desired temperature.
