Fuel Injector Control Using PWM Boosted Voltage

The patent applies periodic pulsed power signals to the fuel injector instead of continuous power. The controller delivers short duration power pulses that open the injector for the required injection period, then removes power to allow complete closure. This periodic action pattern enables the injector to both remain open during injection and close completely between injections, resolving the contradiction between open duration and closure completeness.

The patent applies partial power action by delivering power pulses of precisely controlled duration and magnitude. Instead of applying excessive continuous power, the controller provides just enough power for the required time period to achieve complete fuel injection. This partial action approach ensures the injector opens fully and injects all required fuel while minimizing power consumption by stopping power delivery once injection is complete.

The controller implements periodic power delivery with precise timing control. Power is applied in pulses that duration is calculated to achieve complete fuel injection, then power is removed for a controlled period allowing the injector to close completely before the next injection event. This periodic action with optimized pulse duration reduces power consumption while ensuring sufficient closure time through proper pulse spacing.
